A strange beep sound when starting up the PC

[essdeepee]

Hi,

I have a P-IV (1.5 Ghz) system with intel original motherboard and 768 MB(512mb+256mb) RAM.

My PC is been malfunctioning for over a year.
When I hit the power on button, I hear a serious of beeps (not the usual beep that we hear at the system boot). The led indicators on the system, cd, floppy etc are responding as the system communicates with them. However the monitor doesn't display anything. The led indicators on the monitor keeps blinking. I face this problem occasionaly but regularly...meaning..it happens occasionaly but once it is begun, it happens very regularly from then on. I couldn't really observe when and what makes the system to behave like this. I intially thought that the problem could be with RAM. So I tried changing the RAM but then it didn't help. Sometimes, a slight shake of the system by accident causes this problem and it is getting fixed in the same way :)

What could be the problem? Can anyone help?

Any thoughts or advise would be greatly appreciated. This is been bothering me for a long time.


Thanks,

Prakash

If bumping the case causes it, it sounds like a loose connection somewhere.
Power down, disconnect mains, press the power button and with your wrists (or wrist strap ground lead) resting on the case with it open, re-seat your RAM, video card, power cables, basically anything that can be unplugged and plugged back in.

Also you may be able to narrow down the culprit if you provide us some information about your system and the sequence of beeps so we may be able to look up the beep codes according to your motherboard's BIOS codes.

Also it could be heat related so a good cleaning may help as well.
