So recently the power supply on my system died, and I just installed a new one. It appears to be working fine, except now I need to reset the cmos on every restart or I get a black screen. This presents many problems, as I have to continually change the date and time in windows, and I cannot save bios settings. I put in a new motherboard battery, and flashed the bios to the latest version (2902) using the bios flash utility. Broken board or something else?

specs:585w psu, p5w dh, qx6850, 2gb ram, 7950gt, etc.
