NVRAM and CMOS Checksum Bad

I had a electrical breaker thrown in my house today which knocked out my PC.

Upon reboot, the system recognized memory and HD and hung on checking NVRAM. After waiting several minutes, I rebooted and only got as far as a blank screen with a blinking cursor.

I powered off and cleared the cmos on the back of the motherboard (MSI P7N Platinum). After powering up, I received a "CMOS Checksum Bad" error.

Any suggestions?

CMOS Checksum errors are totally normal when the BIOS is reset. Simply enter the BIOS, reset all the settings as needed for the system, then Save and Exit. When the system reboots, that particular error should disappear. I'm not certain, but the NVRAM hang-up may still occur if in fact the flashable BIOS chip was damaged by the power disruption.

If the NVRAM hang-up does reoccur, you should try removing all components and reinstalling them one by one and attempting to successfully POST. After POST, enter the BIOS and Save & Exit. When the system reboots, see if it will get to the the point where it's looking for a bootable device, then power down and add another component. Use the CPU, RAM, Floppy or Optical Drive, and Graphics Card only for the first attempt, then add other devices one by one, with the hard disk(s) added last.

A camera? Anyone else scratching their head and thinking "WTF?" at the same time? LOL

Just glad ya got it working.

A camera?!! At least it wasn't the headphone plugged into the front panel audio jack. NOW that would be a FIRST!!
