    I haven't got another video card. However I will try re-seating the ram. As for the monitor it is completely blank. The led on the front stayed red and there aren't any beeps.

  • user6name Oct 24, 2008

    I tried changing the video card for the one in my other computer which was also a AGP card. It didn't work. The monitor works on my other computer but not on the Compaq. Like I said, on my the computer which I am using now, the led changed from red to green but on the Compaq it stays red and it doesn't beep. The only sound is from the fans and the disc drives.

    I tried to find the CMOS jumper and saw that the battery on the motherboard has been leaking. Could it be that?

No Beeps?

Could be several things - Re-seat the ram
Could be the power supply, could be the video adapter.
Could be the monitor. Is there any more info you could give. Does the monitor say out of frequency, by chance?

I would assume the video adapter is on-board. Could u try another video adapter in a PCI slot?
Sorry, I will just need some more info to be able to help.

    Hmm - I would remove all the ram, and boot it up, see if it gives any beeps. If not, you have a bad motherboard and thats that. If it does beep, try 1 stick of ram at a time. Also locate the clear cmos jumper and see if you can use it. You would either move the jump over one or move the jumper to a closed loop position. Boot the PC up with the clear cmos jumper enabled, give it 10 secs and then turn the PC back off. Put the jumper back to the original position (not clearing the cmos) and boot back up. I hope this helps.

    G'luck

    Yeah - Battery acid is corrosive. I would not bother with that motherboard any longer.

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.

If a PC suddenly fails to boot properly, you should perform a hard reset as the first action. Performing the hard reset will correct many problems. If the computer still does not start properly, select your symptom from the list below to guide you to the recommended corrective actions.
  1. Disconnect all peripheral devices and remove all USB devices and SD media cards. You want to test the computer not the accessories!
  2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds to drain all residual power and restore default startup settings.
  3. Reconnect the AC power adapter (but do not insert the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a fan or other moving parts turning.
  4. If the computer does not start, the LED lights do not glow, and the display is black, you can perform one or more of the following actions to resolve the no power issue.
    • Verify the computer is receiving power from the AC adapter . Verify that the AC adapter is not damaged and is connected correctly to a working wall outlet plug. Verify AC power is connected to the system board by examining the AC adapter, wiring, and pin connection for damage. The keyboard LEDs will glow when AC power is connected to the system board. Damaged components, like the AC adapter or the pin in the power connector, may require an HP-certified repair.
    • Use a different AC power adapter . If you have access to a different AC adapter or power pack that is designed for the computer, connect it to the notebook and try to start the computer. If you own or have access to more than one notebook, verify that you are using the adapter which belongs to the notebook. CAUTION: Using a power adapter that does not meet the power requirements or has the wrong type of connector may damage the computer. On newer notebook models, connecting the wrong adapter to the notebook may cause the power LED lights to blink but not power the computer.
    • Remove the battery and boot on AC power only . A discharged or defective battery may prevent the AC adapter from supplying enough power to start the computer. To verify that power from the AC adapter is available for PC; remove the battery, connect AC power adapter, and press power button. If available, try using a different AC adapter, that is rated for the PC, and repeat this test.
    • Remove the AC adapter and boot on battery power only . A defective AC adapter may not charge the battery and prevent the computer from booting on battery power only. To verify battery power available for the PC; connect AC power adapter, allow battery to charge for 30 minutes or more, disconnect the power adapter and press power button. If available, try using a fully charged battery, of the same type, from another computer and repeat this test.
      • If LEDS do not glow and the fan or hard drive do not spin, battery may need to be replaced.
      • If tests of both the battery and the AC adapter fail, there may be a problem with system board requiring service by HP.
      • If LEDs glow and PC boots, the AC adapter may need to be replaced.
      • If LEDs glow, but PC does not boot go to LEDs glow, fan is heard, but display is black or blank section.

In this case it is an windows problem you need to reformat your notebook. So that the windows have fresh copy. If the same things happen the problem is the RAM you need to replace the RAM.

Hi:
Since you swapped the power supply already, and have disconnected the DVD, CD, and floppy, that leaves the hard drive and motherboard!

Look the motherboard over, and see if there are any capacitors that are bulging or leaking out on the tops.
Is the inside of the computer very dusty? Check and make sure when you power up the tower, that the cpu fan is spinning up.

Your CPU could be overheating, so removing the Heatsink fan and re applying thermal paste is an option too
If it is, try resetting the CMOS on the motherboard, or pulling the CMOS battery for a minite.
Do you get anything to display on the screen?
If you have more than one stick of memory, take out one of the sticks if possibleif possible.

No video output


Do you get a single beep from the POST at start-up? That signifies that the internal check is OK.

Hey Mike

Go back and check the fine cabling that connects LED indicaters to motherborad. There's got to be a small cable you forgot to plug into the board to feed back poer state. Take your time and check everything twice.
