Boot problems

[randomisedwhite]

Hi

Bit of an unfortunate problem. I was browsing web pages on my pc one day, and the screen suddenly lost video signal, as in the screen went blank.

I rebooted the machine, but the machine now refuses to post. On a rare occasion it will make it past the post screen but will freeze before loading anything associated with the os.

I have swapped out the cpu and video card with older componants that are known to be working and they havent changed the situation. I havent yet changed out the ram.

The system has had a new processor (opty 170) added within the last week but, using an older working processor (64 , 3200+) doesnt help out the problem. Te error codes present on the motherboards vary, but tend towards "C0" which as far as I can tell implicates a motherboard error.

Specs are : Opty 170, @ 2.5 , stable tested prime 95
2gb ram
x800pro @ 560 core
Motherboard: Abit Av8


The overclocks are well stress tested over 48 hours and stable.

So far I can only guess that the motherboard is the culprit.

Any ideas and opinions would be appreciatiated.

Thanks in advance!

Have you got any 'bits' you can swap around from other computers?

Firstly, clear cmos.
Secondly, try disconnecting ALL non essential hw.
What psu?
