    Computer repair guy tested, but I'm not sure how as far as a testbed. He said it had to be either cpu or mobo. I figured I'd start by replacing the cpu. As far as drives being strapped properly, everything appeared to good as far as I could tell.

    It's been down for so long I can't remember if any new programs were installed but I don't think there were. I can't get it to boot in safe mode because it won't go past the compaq splash screen. Pressing any of the keyboard key gets no response. There also are no bios beeps, but on this comp I don't remember ever hearing any on startup.

    Thanks for your response. I disconnected all drives, ram, and cards then powered on. I did get one long beep followed by a pause, and a long beep again. Now that you mention the fan, I did notice something different. As part of trouble shooting I reset the bois by switching the jumpers on the mobo (per compaq website). After doing this I noticed the fan was a lot quieter and seemed to be spinning at normal speed. So I guess you could say it did sound like a small jet before resetting the bios. What next...?

    are all your drives strapped properly? maybe the board is no good. have someone put it on a testbed and see if it will boot that way.

    Can you get it to boot to Safe Mode?

    Have there been any new programs installed just before this happened?

    Have you tried booting to "Last known good configuration"?

If it won't go past the splash screen, and you have replaced the CPU, I agree that it is probably the motherboard.
One other test you can do is, remove the memory chips, and any cards that are plugged it, and see if it beeps on start up.
If it does, count the beeps. If it doesn't it is the motherboard.
If you get beeps, plug the memory back in, and try again. Listen for beeps. Let us know what you find.

And I don't know if Compaq's do this (Dells do) when you turn it on, do the fans spin up normally? Or does it sound like a small jet? Speaking of which, do you see the fans spin up at all?

When I try to boot up, I just get a screen full of aaaaaa

It's sounds like you have a defective keyboard or a corrupt keyboard driver. If you have another keyboard try swapping them out. If not you can try booting the computer with the keyboard disconnected to determine if it's the keyboard. If it's not the keyboard you'll need to boot using a bootable CD and then replace the keyboard driver.

Turn the computer on no matter which button i push

You may have a defective keyboard. A defective keyboard will stop the boot up process. Try another keyboard and see if that fixes your problem.

The system won't boot up and I keep getting a keyboard error that says I need to replace my keyboard

1)chect to make sure a keyboard is in the PS2 port or usb, whichever you are used to. 2)if your computer gets past this screen but does not boot, you will need to reinstall your OS, but this will delete all your data. if your keyboard problem persists, get a different keyboard with the connector you usually use.

Frozen during boot-up, keyboard still works

Sounds like the PC is running into a hardware failure and the Compaq splash screen is probably hiding some additional information. It?s been a long time since I've owned a Compaq, however, what you need to do first is eliminate the Compaq screen to show us whatever boot details it may be hiding. I seem to recall on my old Compaq (and most Dells) I had to disable the Compaq screen in the BIOS settings. Hitting the F10 key as soon as the Compaq screen appears I believe will get you into the BIOS program, however, be warned if you change anything in there by accident you will be causing yourself a world of trouble. After you get into there you want to look for the Boot selection of the menu. In there somewhere will be a setting referring to something similar to ?reveal boot details? or hide splash or Compaq screen?. If it isn?t obvious let me know, I?ll have access to an older Compaq with a similar BIOS and can give you more details. If you are able to disable the splash screen reboot the PC and watch for errors. Based on the age of the machine and past history I suspect you?ll find a boot disk or read error.
