I've been running my system fine without any problems, including up to last night. Now, this morning, I turned it on, and it got as far as the screen showing the IRQ settings and the other misc. hardware info, and then it was ready to go to the Windows load screen, but instead, the screen went blank. Now, the monitor's LED is blue which for my monitor means it's getting a video signal, but there is nothing else happening.
I suspect there is something wrong with the motherboard's RAID chip. I have the MSI KT333 Ultra ARU model. I'm running 2x80GB Western Digital P-ATA hard drives. There is no LED activity from the hard drives during boot up, but the utility that runs when booting that checks the raid states that the array is functional. I unplugged one of the drives and it correctly told me that the array was offline, and then told me it was functional when I plugged it in again. I've tried booting off my Windows CD, but the screen freezes when it gets to the "Checking hardware configuration info".
As you can imagine, I'm really quite confused. The system is extremely stable, and I've had no problems. One thing I haven't done is connect the 4 diagnostic LED's that came with the motherboard, but I'm not sure how much that will help since it seems clear that the hard drives aren't running (or not being asked to run).
Any help you can offer would be greatly appreciated!
