I have an ASUS P5N32-SLI Premium/WiFi-AP motherboard and 2 160GB WD Caviar SE SATA II drives in a RAID 0 using the motherboard's built in RAID controller. I've had this system up and running since 12/06.
This week it started losing the CMOS settings. Sometimes when cold started it goes past the BIOS screen and then stops with an error reading the disk. When I go into the BIOS settings, I see that it has forgotten about the RAID. I can start the system up successfully by re-enabling the RAID.
This has happened 3 times in the last 5 days.
The vendor (AVADirect.com) says I should solve this problem by removing the surge protector and plugging the computer directly in to the wall outlet. They claim that they have had compatibility problems caused by surge protectors.
To me, that sounds insane. It is not plugged in to a UPS, and there's no USB connection, it's just providing power. I don't see how that could cause the CMOS settings, especially since that did not happen until after the system was running for 15 months using the same surge protector. Oh, and the surge protector's "protection good" light is still on, so it does not appear to have been blown.
I would think the problem would more likely be the battery on the motherboard, but I'm a software guy. If it matters, this system is used every day for 6-18 hours, and is shutdown the rest of the time. And also in case it matters, these are the specs, just copied off the invoice.
