Occasional Bad Bios Error

[nekomastermax]

Alright so lately my motherboard has started spitting out a Bad Bios/Checksum error when I overclock and it keeps like that until I remove the battery to reset the CMOS.
I have a 4 year old ASUS M3A78-EM motherboard (Supports AM2, AM2+ and AM3 with the latest BIOS), with a AMD Athlon II x2 270 CPU inside (with 6GB DDR2 ram). I never had this problem before but I'm guessing it's due to aging or maybe I touched something I shouldn't have? (I always ground my self on the case when Im working inside the computer)

I'm currently running the latest bios (r2701) which I got from the Asus website for my motherboard.

Any thoughts on this problem? I don't have the money to replace my motherboard if it really is starting to fail >_>

Anythoughts people? It may be a month or two before I can afford a new motherboard if this one is failing

Does it get the same error without overclock?

Does it get the same error without overclock?

Not really, I havent seen it complain when I return to stock speed (3.4GHz (200x17))

Also now windows 7 isnt recognizing my overclocking, even when I set it up for 3.8 or 4GHz (225 or 235 x17)
