I usually power down my power supply switch when I am not using my PC. Been having problems with bios resetting the time and date clock. I find it odd and assume my battery was about to die. I am using the latest bios which is 0903 and I went to Micro Center and purchased a Duracell CR2032 battery and it works fine the other night. I resetted the CMOS and hit the 2 pins to reset the RTC. So After that the date is fine. Now I am on the PC and it seems to be resetting again? Anyone knows if I need to RMA my motherboard?
