I have my E6300 overclocked to 3.22 ghz and its been stable for about 3 months (passed 12 hours of prime95, as well as Memtest86+). However, on two occasions in the past week, my computer has failed to post, and I had to reset my cmos. After a reset, I get a message that says something about an invalid cmos checksum. Could this be a psu problem? The only hardware changes I have made is connecting another case fan to the mobo header.
