Yesterday just turned on my PC and the system won't post, diagnostic leds show 4 lights on. I tried doing CMOS clear for 10-15sec, 15 min and 8 hours just now, the system still won't post. I had this happened before and I was able to fix it by clear cmos for 15 min.
I am now using a spare Abit mobo and have moved all the components on it and everything works fine. I read in the forum it's possibly bios corruption. I am wondering what to do in this case, I don't even know how it happened, it just stopped posting all of a sudden. Any advise would be helpful, thanks.
Before it stopped posting my system was OCed
AMD Athlon 64 FX-55 @ 2.9GHz (223 x 13)
2 x 1GB Patriot PC-3200 RAM @ 223MHz(1:1)
