This computer would blue screen and the tests showed that one of the disks was bad (three disks - two stripped in RAID - one with data). This disk was HD 0 with the operating system. I replaced it with a different SATA HD that was not RAID. It worked fine for several days. I attached the (non-member) SATA that had separate data on it that wasn't on the RAID drives - and the computer blue screened. I disconnected it and now the computer blue screens, anyways - with the new SATA. Is there anything with the BIOS that I should be doing to take a computer that used to be RAID (stripped) and not isn't? Every time I start the computer it says "strike the F1 key...).
