Hey there, been visiting AnandTech a long time but only now signed up to the forums. Basically half the time I reboot I hey this CMOS checksum bad error and sometimes it also says overclocking failed (the pc is no longer overclocked). Now it gives me 2 options: F1 to run SETUP or F2 to load defaults and continue. If i hit F2 it will either tell me I have a disk read error and prompt me to ctrl+alt+del to reboot (my hard drives are perfectly fine) or it will fail to see my boot drive entirely and ask me to select a boot device and reboot.
When I hit F1 and went to setup i tried loading defaults but that didnt help, if i load defaults and select the proper boot device then save and exit it just gives me the CMOS error again after it reboots. Basically I have no idea whats causing this error and booting my pc is now purely a luck based affair of trial and error until it just boots without error. I forgot to mention that sometimes it wont POST at all and ill simply see a black screen while all my fans are still running as if the pc is on.
I have to mention i tried the obvious fix to this error which was replacing the CMOS battery which did nothing. I did a full virus scan since I read a virus or trojan could have messed with the CMOS data but came up empty. The motherboard by the way is an ASUS P5B Deluxe (its a fairly old computer but im waiting for sandy bridge) at this point im thinking my BIOS is just crapping out and ill have to replace the mobo which im really hoping to avoid at this point so any help regarding the matter would be greatly appriciated.
