It all started sometime earlier today, when my RAID 1 array failed, and I noticed a few hours ago that all the directories on the RAID partition were blank, except for the root directory itself and My Documents. None of the files were readable. I rebooted, and indeed, the "Intel Matrix Storage Manager" BIOS screen stated that both disks had errors.
I rebooted it again, but all of a sudden it wouldn't boot, no POST beep and no monitor image (on this particular motherboard, the monitor image never appears until after POST though - I don't know if that's common behavior)
The normal fan behavior when I turn on the PC is that the fans go on for less than half a second, go silent for a few seconds, and then I get the POST beep - but now, they just keep spinning at full speed. I had to hold the power button for 5 seconds to turn it off.
The RAID 1 array was working this morning, and some time later an app (that happened to reside on the RAID partition) crashed with a weird error message. I didn't think much of it then, but that was most likely at the time the RAID array failed, since I've never seen that error message before. If so, the PC had been running for several hours with the failed RAID array (before the PC failed completely when I decided to reboot)
Since I'm using the onboard ICH10R hardware RAID, the 2 issues are most likely related. Does anyone have an idea of which component is most likely to be faulty? If I can isolate which part is faulty, I can send it in for repair. Is it likely to be the RAM at all? Could faulty RAM affect the RAID controller in such a way?
Update: The PC now turns off during POST. The fans spin up, the DVD drive spins up, and a few seconds later it turns off.
