The most important part of a computer case is its power supply. Unfortunately, it's also the part that has most of the problems for a case. There are two situations when a new power supply may appear dead on arrival (DOA) when they are actually working as described below:

Most cases and power supplies these days are made and tested in China and other Asian countries where 220V electricity is used. Desktop computer power supplies do not switch the power voltage automatically. (Most notebook computers do!) If the factory forgets to turn the manual switch back to 110V for the North American market after testing, the power supply would appear DEAD if you use on a 110V-outlet. Therefore, always check the voltage setting on the back of a new power supply FIRST if it appears dead.

Do not expect an ATX power supply to work by simply plugging the power and turning on the switch. ATX power supplies are soft-switched on and off by the motherboard and BIOS. Therefore, you must plug it to a working motherboard with a working microprocessor, memory and video card to work. If your computer does not turn on after you turn on the power switch, it may not necessarily mean a dead power supply. The problem might be with the motherboard, microprocessor, memory or video card instead. You must examine all these components to isolate the problem.

The most effective technique to tell if a power supply is causing any problem is to use a different one to see if it solves the problem. If everything works with a different power supply, then the new power supply is most likely the troublemaker. Alternatively, you can plug the new power supply to an existing, working computer to see if it works there.

Computer cases are highly modular. If your computer case is still under warranty, you don't have to send the entire case back if only one part of it is defective. For instance, send only the power supply back for exchange if only power supply is dead. The same is true for the face panel and cover. This would save you quite a bit of shipping and sometimes downtime.

More than 70% of all computer problems are related to cabling and connections. Ensure that you all the power plugs are connected firmly, including power connections to your motherboard and all the drives.

Make sure the cooling fan inside the power supply is working all the time. Reach out to feel the fan behind your case often. Clean the fan if necessary. If your case feels warmer than room temperature, check the power supply fan first. Most power supply fans are difficult to replace. You are better off to replace the entire power supply since the new one comes with a brand-new warranty.

Before ATX form factor became popular, the compatibility between a power supply and a specific motherboard could be problematic. However, this problem nowadays does not happen very often any more.

The rest of a case is mostly mechanical. You should be able to find a way to get around most of the problems if you are mechanically inclined.

The following troubleshooting tips may help if you experience problems.

Check that the card is seated properly in its expansion slot. Some AGP cards have design flaws and are "well-known" to "pop out" during transportation. For PCI cards, if the problem still exists, try a difference PCI expansion slot.

Ensure the display cable is securely fastened to the card's display connector.

Make sure that the display and computer are plugged in and receiving power.

If necessary, disable any built-in graphics capabilities on your motherboard. For more information, see your computer's manual.

Make sure you selected the appropriate display device and graphics card when you installed your enhanced driver.

If you have problems during start-up, start your computer in Safe Mode. In Windows 98, press the F8 key when "Starting Windows 98" appears; or, in Windows 98, press and hold the CTRL key until the Windows 98 Startup Menu appears on the screen. Then select the number for Safe Mode, and press Enter

• If you use your computer more than a few hours per day, we suggest you not to turn off your computer at the end of the day. Instead turn off only the monitor to save electricity. Daily power up and down makes the components exposed to high and low temperature cycles that are not good for the life-time of the components, particularly the critical ones such as hard drives, CPU, and memory. The temperature cycle would result in expansion-shrinking cycle for the components. The life-time of electronic components would be increased if they are run at constant temperature with adequate ventilation.
  
  
• If your area experiences a few times of power outage per year, it is necessary to use a UPS. Sudden power downs while the system is running may cause severe damage to hard drives.
  
  
• A tape backup and a lock to make systems hard to move are worthy investment for critical data.
  
  
• Use your hand to touch and feel the cover of your computer at least once a week. The cover should be at room temperature. If it feels warm there may be a problem! Check to make sure that the cooling fans on the power supply and CPU are working properly. Clean the air pathway on the back of the power supply on a regular basis.

Hard drives are one of the most failure prone components in a computer, but luckily, most carry a good warranty. Directron provides a one-year warranty from the purchase date on all hard drives they sell; other retailers have similar policies. The drive manufacturer's warranty often extends for quite a bit longer than the retailer's warranty. Some manufacturers offer warranties of up to five years after the date of purchase.

If your drive fails, you should first check to see if you can return it to the retailer you purchased it from. You can do this by visiting the retailer's website and finding their warranty policy. Directron's warranty policy can be found here. The warranty policy should tell you how long the warranty on your drive lasts, and how you can go about returning your drive. If your drive is no longer under warranty by the retailer, you can attempt to return it to the manufacturer. This guide will help you do so.

Returning hard drives to the manufacturer is actually a fairly easy task. Most manufacturers have helpful websites that allow you to easily request a return merchandise authorization (RMA). Before you RMA your drive, you should back up your data if the drive is still accessible. Some methods for temporarily reviving a failed hard drive to recover data can be found here. If still inaccessible, the only way to recover your data is to let a data-recovery service do so for you. The manufacturer will not attempt recover your data.

Below are instructions for returning drives to the common manufacturers. Click on a name to jump to the instructions for that manufacturer:

Additionally, this article contains links to resources that can help you troubleshoot if problems occur.

INTRODUCTION

This step-by-step article describes how to partition and format a hard disk with Windows XP.

Before you can install an operating system, you must first create a primary partition on the first physical hard disk (Disk 0) on your computer, and then format a file system on that partition. This partition is named the System partition. Alternatively, you can create a separate partition for the operating system on any physical hard disk. This is named the startup partition. The System partition on Disk 0 can also be used as a startup partition

MORE INFORMATION

Options for partitioning and formatting your hard disk

You can use the Microsoft Windows XP Setup program or the Fdisk and Format tools to partition and format System and startup partitions.

For additional information about how to use Fdisk and Format to partition and format your hard disk, click the following article number to view the article in the Microsoft Knowledge Base:

Important things to consider before you partition and format your hard disk

Consider the following questions before you partition and format your hard disk:

• Have you prepared the hard disk by following the manufacturer's instructions?
  
  Set the jumpers and the cabling according to the role of the hard disk (for example, master or subordinate) and make any required BIOS (or CMOS) changes. See the documentation that came with your hard disk and motherboard, or contact the manufacturers.
  
  
• What type of file system do you want to use?
  
  You can use either the FAT or NTFS file systems.
  
  For additional information about the differences between the FAT and NTFS file systems, click the following article numbers to view the articles in the Microsoft Knowledge Base:
  
  Overview of FAT, HPFS, and NTFS file systems Description of the FAT32 file system in Windows XP
  
  
• Does the hard disk already contain data? If yes, have you backed up all your important data?
  
  If not, back up your data before you continue. When you partition and format a hard disk, all the data on that partition is permanently deleted. You can view current partition information without deleting your data.
  
  For additional information about how to use the backup utility or the Files and Settings Transfer Wizard, click the following article numbers to view the articles in the Microsoft Knowledge Base:
  
  How to use the Backup utility to back up files and folders in Windows XP Home Edition

  How to use the Files and Settings Transfer Wizard
  
  How to use the Files and Settings Transfer Wizard from CD-ROM
  
  How to use the Files and Settings Transfer Wizard Disk in Windows XP
  
  
• Does the hard disk have a drive overlay or a disk management program?
  
  If your computer uses drive overlay software for large hard disk support, do not use the Windows XP Setup program to partition or to format the drive until you have verified Windows XP compatibility with the software manufacturer. If you do not know whether you have drive overlay software installed, contact the software manufacturer before you continue.
• Do you have the floppy disks or the CD-ROMs that you need to reinstall your software?
  
  Make sure that you have the software so that you can reinstall your programs after you partition and format your drive. If you purchased an upgrade for a program, make sure that you have the full version of the original program. Many upgrades for programs require a compliance check before you can install the upgraded product. If you cannot find the original floppy disks or CD-ROMs, contact the software manufacturer before you continue.
• Do you have updated device drivers backed up on storage other than the drive that you want to format and partition?
  
  If you have installed an updated device driver for your peripheral devices (for example, modems and printers), make sure that you back up the new driver for the device to a location other than the drive that you want to format and partition. Therefore, you can reinstall it after you install your operating system.
• Can you start your computer from the CD-ROM drive?

How to partition and format your hard disk by using the Windows XP Setup program

Important If you follow these steps on a hard disk that is not empty, all the data on that hard disk is permanently deleted. We recommend that you back up your hard disk before you follow these steps.

To partition and format your hard disk by using the Windows XP Setup program:

1. Insert the Windows XP CD-ROM into your CD-ROM drive or DVD-ROM drive, or insert the first Windows XP Setup disk into the floppy disk drive, and then restart the computer.

Note To start your computer from the Windows XP CD-ROM (or from the startup disk), your computer must be configured to start from the CD-ROM drive, the DVD-ROM drive, or the floppy disk drive. In some cases, you may have to modify your computer's BIOS settings to set this configuration. For information about how to configure your computer to start from the CD-ROM drive, the DVD-ROM drive, or the floppy disk drive, see the documentation that is included with your computer, or contact the computer manufacturer.

2. If you are starting the computer from the Windows XP CD-ROM, select any options that are required to start the computer from the CD-ROM drive if you are prompted to do this.

Note If your hard disk controller requires a third-party original equipment manufacturer (OEM) driver, press F6 to specify the driver.

For additional information about how to use F6 to supply a third-party OEM device driver while the Windows Setup program is running, click the following article number to view the article in the Microsoft Knowledge Base:

314859 Limited OEM driver support is available with F6 during Windows XP Setup If you are starting from the Windows XP Setup disks, insert each of the additional disks when you are prompted, and then press ENTER to continue after you insert each disk.

3. At the Welcome to Setup page, press ENTER.

4. Press F8 to accept the Windows XP Licensing Agreement.

5. If an existing Windows XP installation is detected, you are prompted to repair it. To bypass the repair, press ESC.

6. All the existing partitions and the unpartitioned spaces are listed for each physical hard disk. Use the ARROW keys to select the partition or the unpartitioned space where you want to create a new partition. Press D to delete an existing partition, or press C to create a new partition by using unpartitioned space. If you press D to delete an existing partition, you must then press L (or press ENTER, and then press L if it is the System partition) to confirm that you want to delete the partition. Repeat this step for each of the existing partitions that you want to use for the new partition. When all the partitions are deleted, select the remaining unpartitioned space, and then press C to create the new partition.

Note If you want to create a partition where one or more partitions already exist, you must first delete the existing partition or partitions, and then create the new partition.

7. Type the size in megabytes (MB) that you want to use for the new partition, and then press ENTER, or just press ENTER to create the partition with the maximum size.

8. Repeat Steps 4 and 5 to create additional partitions if you want them.

9. If you want to install Windows XP, use the ARROW keys to select the partition where you want to install Windows XP, and then press ENTER. If you do not want to format the partition and install Windows XP, press F3 two times to quit the Windows Setup program, and then do not follow the remaining steps. In this case, you must use a different utility to format the partition.

10. Select the format option that you want to use for the partition, and then press ENTER. You have the following options:

• Format the partition by using the NTFS file system (Quick)
• Format the partition by using the FAT file system (Quick)
• Format the partition by using the NTFS file system
• Format the partition by using the FAT file system
• Leave the current file system intact (no changes)

The option to leave the current file system intact is not available if the selected partition is a new partition. The FAT file system option is not available if the selected partition is more than 32 gigabytes (GB). If the partition is larger than 2 GB, the Windows Setup program uses the FAT32 file system (you must press ENTER to confirm). If the partition is smaller than 2 GB, the Windows Setup program uses the FAT16 file system.

Note If you deleted and created a new System partition, but you are installing Windows XP on a different partition, you will be prompted to select a file system for both the System and startup partitions. 11. After the Windows Setup program formats the partition, follow the instructions that appear on the screen to continue. After the Windows Setup program is completed, you can use the Disk Management tools in Windows XP to create or format more partitions.

Fax/Modem Troubleshooting Tips

You are encouraged to make links to this article from your website and tell your friends

The following general-purpose advises are provided as a free service to our customers and visitors. Actual procedure may vary among brands. Read your product user manual carefully before any work. Directron.com is not responsible for any damage as a result of following any of these advises. You are welcome to distribute these tips free to your friends and associates as long as it's not for commercial purposes.

My modem is a 56K, but I can connect to the Internet only at slower speed.
The current copper wired telephone lines are limited only to about 53K. If you are connected only to 33.6 or 28.8K, check the following first:

• Is your modem compatible with the modem used at your ISP?
• Is your modem set up to run at full speed?
• What's the maximum speed your ISP allows?
• How far away are you from your ISP?
• Some modems need special initiation strings to get full speed.
• Some conditions are out of your control, such as weather and conditions of the telephone lines in your community.
• Problems may occur when you are dialing through a phone system such as one in a hotel.

Modem answers incoming calls and then returns to the on-hook condition, disconnecting the caller:
This occurs most often when connecting to a UNIX system. In most case, the host does not prefer to see any result or command echo codes. If this is the case, the codes can be disabled by adding E0 Q1 to the modem configuration string.

The modem dials and appears to complete the connection, but the communications software does not enter the correct mode. (The screen remains blank)
This is normally caused by an I/O address or IRQ conflict. Verify that the COM port is not in use by any other serial device and if necessary use another COM port or I/O address settting. Refer to your computer manual on how to determine what serial ports are installed.

The modem dials and appears to complete the connection, but the communications software does not enter the correct mode. (The screen remains blank)

• There may be an I/O conflict (see the solution for the previous problem).
• The Result Codes may have been disabled by the software configuration set up. Check if Q1 is in the configuration or initialization string. If so, change it to Q0.
• Your software may require numeric result codes rather than verbal result codes. Use either V0 for numeric result codes or V1 for verbal result codes in your initiazation or configuration string.
• Some software require full extended result codes (i.e., CONNECT 33600 instead of CONNECT). This can be controlled by the Xn command. X0 sends a summarized code (CONNECT) and X4 sends a full extended code (CONNECT 33600)

The modem does not auto answer
The auto answer mode is determined by the S0 register. If S0 has been set to 0, the modem will not answer. Asign another value to S0 by entering the following command: S0=n, where n = the number of rings to occur before the call is answered (ATS0=2, the modem answers after two rings)

The modem always answers the phone.
Set the S0 register to 0. ATS0=0.

The communications software displays, "No Dialtone."
Make sure that your phone cable is working properly and that it is firmly seated to the phone socket at your phone jack and in the real panel of the modem.

A high pitched squeal is emitted from the external speakers
This phenomenon is "feedback" and occurs when the microphone is pointed at the external speaker or is close enough to pick up the speaker output. This may be remedied by using a unidirectional microphone, making sure that it is pointed away and as far from the speaker as functionally possible. Another option is to use a headset with an attached microphone.

| Choose Motherboard | Motherboard Installation Guide |

More than 70% of all computer problems are related to cabling and connections. Ensure all cables are connected and connected firmly. IDE and floppy ribbon cables and power cables can often go loose. Ensure microprocessor, memory modules, and adapters such as video card are inserted correctly and didn't "pop-up" due to vibration.

System has no power at all. Power light does not illuminate, fan inside the power supply does not turn on, and indicator light on keyboard does not turn on.

PROBABLE CAUSE	DIAGNOSIS	SOLUTION
Power cable is unplugged.	Visually inspect power cable.	Make sure power cable is securely plugged in.
Defective power cable.	Visual inspection, try another cable.	Replace cable.
Power supply failure.	Power cable and wall socket are OK, but system is still dead.	Contact technical support
Faulty wall outlet;circuit breaker or fuse blown.	Plug device into socket know to work and test.	Use different socket, repair outlet, reset circuit breaker or replace fuse.

System inoperative. Keyboard lights are on, power indicator lights are lit, and hard drive is spinning.

PROBABLE CAUSE	DIAGNOSIS	SOLUTION
Expansion card is partially dislodged from expansion slot on the motherboard.	Turn off computer. Take cover off system unit. Check all expansion cards to ensure they are securely seated in slots.	Using even pressure on both ends of the expansion card, press down firmly on expansion card.
Defective floppy disk drive or tape drive.	Turn system off. Disconnect the cables from one of the floppy drives. Turn on the system, check to see if the keyboard operates normally. Repeat until you have located defective unit.	Contact Technical Support.
Defective expansion card.	Turn computer off. Remove an expansion card.	Make sure expansion card is secure in expansion socket.

System does not boot from hard disk drive, can be booted from floppy disk drive.

PROBABLE CAUSE	DIAGNOSIS	SOLUTION
Connector between hard drive and system board unplugged.	When attempting to run the FDISK utility described in the HARD DISK section of the manual you get a message, INVALID DRIVE SPECIFICATION.	Check cable running form disk to disk controller on the board. Make sure both ends are securely plugged in; check the drive type in the Standard CMOS Setup (in your motherboard manual).
Damaged Hard Disk or Disk Controller.	Format hard disk; if unable to do so, the hard disk may be defective.	Contact Technical Support.
Hard Disk directory or FAT is scrambled.	Run the FDISK program, format the hard drive(See HARD DRIVE section of manual). Copy your backup data back onto hard drive.	Backing up the hard drive is extremely important. All Hard Disks are capable of breaking down at any time.

System only boots from Floppy Disk. Hard Disk can be read and applications can be used, but booting from Hard Disk is impossible.

PROBABLE CAUSE	DIAGNOSIS	SOLUTION
Hard Disk boot program has been destroyed.	A number of causes could be behind this.	Back up data and applications files. Reformat the Hard Drive as described in the Hard Drive section of the manual. Re-install applications and data using backup disks.

Error message reading "SECTOR NOT FOUND" or other error messages indication certain data is not allowed to be retrieved.

PROBABLE CAUSE	DIAGNOSIS	SOLUTION
A number of causes could be behind this.	Use a file by file backup instead of an image backup to backup the Hard Disk.	Back up any salvageable data. Then do a low level format, partition, and high level format of the hard drive( see Hard Disk section of your manual for instructions). Re-install all saved data when completed.

Disk formatted on IBM PS/2 will not operate with this system.

PROBABLE CAUSE	DIAGNOSIS	SOLUTION
The IBM PS/2 uses a different format than other computers.	IBM PS/2 disk format will not work in an AT type computer.	Format disk in the AT type computer insert disk into the IBM PS/2 and copy the files you wish.

After install an expansion card (network card, tape drive card, etc.) the system no longer works properly.

PROBABLE CAUSE	DIAGNOSIS	SOLUTION
No power to monitor.	All or part of the system may be inoperable. The new card may work but a mouse or COM port may not work.	Change the interrupt or RAM address on the new expansion card. See the documentation that came with the new card in order to change pin settings. many expansion devices come with proprietary software that will assist you in doing this.

Screen message says "Invalid Configuration" or "CMOS Failure."

PROBABLE CAUSE	DIAGNOSIS	SOLUTION
Incorrect information entered into the configuration (setup) program.	Check the configuration program. Replace any incorrect information.	Review system's equipment. Make sure correct information is in setup.

Screen is blank.

PROBABLE CAUSE	DIAGNOSIS	SOLUTION
No power to monitor.	Power connectors may be loose or not plugged in.	Check the power connectors to monitor and to system. Make sure monitor is connected to display card, change I/O address on network card if applicable.
Monitor not connected to computer.		See instructions above.
