Not yet. Don't want to turn it off till I've done the stuff I need to do! I'll report back when I do...

maybe a faulty BIOS chip?

Possible mate but my vote is with the PSU supply. If not that then I think rebuilding the Raid would help totally rebuild it from scratch even as far as new leads and checking the hardware connections on mobo about 3times..

Where abouts is your operating system? Is it on your RAID drive? If so your PC will not boot if your BIOS settings are set to default. I've got one of these boards from ASUS and occasionaly for no reason at all it just resets the boot settings to default. Might be some sort of fail safe but seriously annoying if your OS is on your RAID drive. Just need to nip into the BIOS and do this:

1. Select BOOT menu,
2. Highlight Other Boot Device
3. Press enter and select SCSI/Onboard ATA Boot Device
4. Use the + key to move it to the top of the boot list
5. F10 to save changes and exit

HTH :)
