Odd problem with bios.

AndyRST · 21 Aug 2008 at 22:18

I have a "old skool" P4 2.8ghz on a Abit ic7-G. All has been working fine for years now until the other day for no reason while im using it the screen goes blank and it starts to reboot itself. It does the 1st check which is the graphics card version and then stops and gives me a message of

"Bios Checksum error"

"insert system disc into A: and press enter"

So far tried new bios battery and reset the cmos jumper but no luck.

Tried a bios disc in A: and it starts to load and gets halfway, then the screen goes mad with coloured blocks and symbols all over and stops loading the bios disc.

Any ideas or is it a dead motherboard?

Cheers for any help

Could be more than 1 fault. Based on the wierd colours I would try it with a different video card before starting with the BIOS.

Ok but i dont have another gfx card to try in there. The screen only goes mad once its started to load the bios.

what to do with an old system like this. Dont really want to upgrade to a new spec as bought most of the bits from ocuk and system runs really well dispite its age but where do you get bits like m/b's for old P4's with agp gfx card.

Corruption on the BIOS screen sounds like broken video RAM. I had an old Nvidia card do that to me when I was moving it into a different PC. It was corrupting the display under Windows as well although it still worked just about well enough to use. I think I gave it a static shock when moving it.
