|Are you saying that your CMOS is corrupted? You description of the problem is not very clear.|
If it is a BIOS corruption problem, then try this:
Go into the BIOS (Del key or F2 key normally) and try an load "Fail-Safe defaults" or load "Optimised defaults" that may clear the problems.
If that is not the problem try and provide a clearer explanation of your problem.
☺ When everything else fails, read the instructions.
