Bad check sum cmos


This error is not the same as a CMOS Checksum Error, which refers to corrupted values of the CMOS settings, the ones you set through the BIOS setup program. This error means the contents of the BIOS code itself are damaged.

Reset BIOS on HP Pavilion a750w


Fastest way to reset BIOS is to remove the CMOS battery (looks like a large watch battery on Motherboard) for 30 minutes. After you replace the battery, the BIOS should reset to default. If further problems arise involving the BIOS, it's possible the CMOS battery is bad.
