Maximum PC

Hiya, folks! I just upgraded to a band new OEM Biostar G31-M7 TE motherboard. After the first day or so, the time and date began messing up, such that I've had to manually enter them at boot-up time every time after I turn off the power. I've already swapped out the battery twice, and it STILL gives me this problem! Does this mean that the CMOS is fried, or what? The mobo runs fine otherwise (except possibly for the SATA ports, a problem I've documented separately in another forum). Any suggestions? Thanks in advance!

Sure sounds like CMOS/BIOS corruption to me, especially if the problem isn't fixed after battery replacement.
I'm very much against flashing a BIOS update if the board is under warranty. I'd RMA it.

Unfortunately, the board is both out of warranty and out of production, so it looks like I'll have to try re-flashing the CMOS--either that, or replace the CMOS chip, which on this mobo is surprisingly easy to do! Thanks again for the prompt response!
