The problem's onset is sudden, happening after the system was idle several hours. First I noticed I had no video. I hit the Reset button, and after that there was never a POST beep and the video never turned on. Next I tried switching off the power supply. After starting back up, the hard drives spin up, but there was still no beep and no video. The POST LED first displays EA, then 01, then 68, then 02. I looked up each number in the manual but can't tell what the failure is (especially when two of them only say "Reserved"). Is there any hope for this board?
