Solved: CMOS Checksun Error-Defaults Loaded
I am having trouble correcting this error. A friend of mine asked me to look at his computer for him. He was using it one day and it just shut off out of know where. It would not start again. I discovered shortly after looking at it, that the PSU had to be replaced. I proceeded to buy a new PSU and I installed it. Everything started just fine. However, when I get a CMOS Checksum error. I can press F1 to continue or DEL for setup. I hit F! and it proceeds to detect array under "NVIDIA RAID IDE ROM BIOS".
It does nothing after this. I tried reinserting the CMOS battery, I loaded factory settings on the BIOS ( RAID is OFF), but still it does nothing. Any help would be appreciated. I have to get this computer back to him soon.

Have you put in a new CMOS battery? Is the date/time correct in BIOS?

The cmos battery is probably a 2032 battery available just about anywhere; even walmart carries them. Go buy one and install it; pw ON and enter the bios. Load defaults, set time, date, boot order, and sata mode. Save settings and restart. See if you still have the problem.

Hey it worked, everything is back to normal, thank you. Also, the DVD player stopped working mysteriously. It will not even power on. I checked the connections from the power supply to the DVD player, and I tried different ones, but still no life. Do you think when the PSU died it took the DVD player with it?

Very possible. DVD drives are very cheap; $20 at the egg. If you have tried a different pw connector and data cable, then most likely the drive has failed. Here is a link to a $20 drive.
