Even ran for about 35 minutes.
I left it to work out, or else I'd have been there for four hours, came back, changed the resolution, Windows said it needed to be restarted to save some changes, so meh, why not?
Oh...I'm back to not being able to find any bootable media.
Now I have a theory. I think it may be the CPU has an issue with being even remotely warm. I put it in the freezer, will pull it out after about 20 minutes, and see if it boots. If it does, I'll reboot, and see if it's okay. If so, I'll let it get warm, then reboot one more time. I suspect it'll do nothing and then I have my answer.
I'll be back when I determine a pattern. This AMD Phenom II x6 has never gotten above about 42C, I don't know what the problem could be with it. It's a 3.2g, so I don't bother OC'ing it. Though, for the past few months, my monitor...don't remember which one...shows it going from 3.2 -> 0.8 -> something else -> back to 3.2, eventually, but never staying in one place for more than a couple of seconds, at most, even when the machine is idle.
edit: That changed nothing. After resetting the mobo, putting it back together, upon initial boot, it went right through the Gigabyte splash screen and froze at the steady cursor indicating no boot devices. No prompting about it being reset, nothing.
A quick jab at the reset button, and, oh, here's that prompt. Yeah, load defaults and reboot. I go into the BIOS after rebooting, 'cause this is exactly what I did, before, and change it to IDE, save and restart...back to a steady cursor.
That's it for me. I give up. Ten days is long enough to work on this. Working one time out of a couple of hundred is not acceptable.
