Blue Screen Crashing Comp

Everynight when i turn off the computer screen and go to bed, i wake up to a blue screen on the computer that says crap about my bios and it failing. Just wondering if anyone ever gets the error and what they did for it? It crashes my computer and makes me loose everything I am doing.

I was told I need to flash the bios but i am not sure how to do that, I am on a soltek mobo, windows xp, amd proc.

Thanks
