It's possible you are using a USB keyboard and it is not being detected. You should be able to turn the caps lock light on and off if it is working. Try a ps2 keyboard.

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your "((MOTHERBOARD TO YOUR HARD DRIVE))" make sure they have a secure connection and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error even something as small as a faulty electrical extension or fan lead can cause this problem follow the troubleshooting procedure a computer needs all of the data and electrical current to travel through every device and to have an end to be able work properly

a motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail check all electrical extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working hope this helps also it could be a dirty computer clean all of the dust from your computer you could use a vacuum cleaner but whatever you use make absolutely sure there is no moisture gets to anything in your computer

also check the Cmos battery and computer ram make sure they are securely seated

hope this helps

Does not boot up, fans start, internet plugs light, clicks on and off.....seems this is a common problem for these machines, what is the fix?


Instructions
  1. When you press the Power button to start the boot process, the LED lights glow while the computer verifies that there is sufficient electrical power to activate the hardware.

    Effect & Solution: When you press the power button, the LED lights on the computer do not glow or the LEDs blink briefly and then stop. There is no sound of the fan or hard drive spinning, and the screen remains blank. The computer will not start if there is insufficient battery or AC adapter power.
  2. The BIOS queries various hardware components used for the startup boot process.

    Effect & Solution: When you press the power button, the LEDs glow but there is no fan or hard drive sound. The LEDs may glow briefly and then go out.

    Or

    The LED lights blink, stop, and then blink a second or third time, but there is no sound from the computer and the screen remains blank. The sequence of the blinking lights indicates a specific error code.

    Or

    A series of beeping tones is heard. The sequence of beeping tones indicate a specific error code.

    If a hardware component has recently been replaced, or if the PC has been jarred or shaken, there may be a loose connection to the memory chips or hard drive which prevents the computer from starting.
  3. The BIOS loads the basic input (keyboard) and output (advanced LEDs / display screen / boot drives) devices into memory.

    Effect & Solution: When you press the power button, the LEDs glow, the fan or hard drive sounds, are heard, but then the boot process stops and a black screen - with an error message - displays.

    The boot check has detected a communication error or conflict with a hardware component that must be corrected.
  4. The BIOS loads the Windows operating system and starts the services that allow low-level control of all of the background operations.

    Effect & Solution: When you press the power button, the LEDs glow, the fan or hard drive sounds, are heard, the HP or Compaq Logo displays on a black screen, but then the boot process stops and a blue screen - with an error message - displays.

    The boot check has detected a hardware driver error or a software conflict that must be corrected.
  5. Control is transferred to the Windows loader to initiate the display of the advanced settings in the Windows environment.

    The Windows logo displays during this step.

    Effect & Solution: When you press the power button, the computer performs all the steps in the boot process, but after the Windows Logo displays, the moving Windows progress bar or the rotating cursor stops moving and the boot process stops.

    An error message may display on a screen with the Windows logo. In some instances, there is no specific error message.

    Or

    A black screen appears and the computer attempts to restart.

    The Windows self-check has detected a software conflict that must be corrected.

You may be able to purchase a system disk from Compaq, otherwise, try any generic XP disk. It won't have any Compaq drivers, but at least you can reformat the C: drive and get XP on it.

Boot failure Asus P5Q-EM


Disk boot failure. Issue:Disk boot failure.
Cause: This issue could be caused by any of the below possibilities.
  1. Boot options are not set properly in CMOS
  2. Non bootable disc or USB in computer
  3. Remove added hardware /check connections
  4. Hard disk drive is bad
Solution:Boot options are not set properly in CMOS
Verify that the boot options within CMOS are set properly. Below is an example of how we recommend the boot options be set. Additional information about how to enter CMOS can be found on document CH00192.
  1. Floppy drive
  2. CD-ROM drive
  3. Hard Drive
  4. Other / Network
Non-bootable floppy diskette or disc or USB in computer
Verify that there is no floppy diskette or disc in the computer. If the boot options are set improperly the computer could be trying to boot from the disc drive instead of the hard drive.
In addition to verifying there is no disc in the computer make sure that no USB jump drive, external hard disk drive, or memory stick is inside any memory card reader.
If you're wanting to boot from a floppy diskette, CD, DVD, or USB drive and are getting this error message and have verified that your CMOS settings are in the proper order as explained in the above paragraph the diskette or disc you're using is either bad or does not have the proper files on it to make it bootable.
  • Additional information about how to make a boot disk can be found on our boot disk help page.
  • See document CH000669 for information about creating a bootable disc.
Remove added hardware / check connections
If you've recently installed any new hardware it's suggested that it be removed to verify it's not causing this issue. If after the device has been removed the computer works and it was another IDE / EIDE device ensure that the jumpers are properly set on the hard disk drive.
In addition to removing any new hardware it's also suggested if you've recently moved the computer or installed anything inside the computer that the connections for the drive be checked. Usually it's best to simply disconnect the cables from the back of the drive and reconnect them to make sure they're connected properly. While inside also disconnect and reconnect the cable connected to the motherboard as well. While inside your computer make sure you're aware of ESD.
Bad hard disk drive
If you have followed the above steps and you continue to experience the same issue, unfortunately it is likely that the hard disk drive is bad or the controller is bad.
If available, you may want to connect another known good hard disk drive to the computer to determine if it can be detected. If it is able to be detected then replace your hard disk drive. If it is not detected, unfortunately you will need to replace the motherboard or controller as it is bad.
If no additional hard disk drive is available it is recommended that the hard disk drive be replaced first or that the computer be serviced / repaired.

My hard disk would not open


is the hard disk detectable in the cmos setup? to know how to enter the cmos setup look for the press "DEL / F2 / F10 to enter setup when you power up the pc. check for the boot option under cmos and check the hdd if cmos can detect it. otherwise hard drive has a problem. if hard drive is detectable, try reinstalling windows xp. other means is to check boot sequence by pressing F11 during start up. this will display the option on which you would like to boot from.

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.

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.
