My computer has developed a problem, it will not boot up, nothing happens the screen stays blank like its not even connected. Sometimes if I try to switch it on it will make one long beep followed by four short beeps and shut down. However, if remove the motheboard battery for a minute or two it will boot up just fine.


I have tried unplugging all devices, video cards, and trying different RAM sticks... same problem.

Any ideas?

what pc do you have, some specs? coz one short and four long beeps is a specific error from the mobo.

Its a system I built. Abit AN8 32X MB. Problem is all AMD 939 processors and MBs have pretty much been discontinued. I can find some socket 939 MBs but none that are SLI.

Sucks.

Looks as if something is messing up the cmos settings. By taking the battery out you force the computer to boot on default values.

1: Use a voltmeter to check the battery voltage. It should be above 3.0 volt.

2: Are there any devices near the computer that can create electromagnetic interference (electric motors, heavy load electrical switches, flashing neon lights etc.). If yes, try to remove the computer away from them (if possible).

3: Another source of problem could be an unstable power supply unit. Try to replace it.
