Sunday night–Sunday the 5th–I found that my desktop had died. Sunday night is a bad time to start poking at machines, so I left it until Monday. There was some tentative poking and attempts to get it to boot, and it was up and running for a while, but not for more than an hour and a half.
It went into the shop, and came home Friday with a diagnosis of “could not reproduce problem, very dusty, should be fine now that the heat sink’s cleaned.” And it worked! Ran perfectly. (I took this opportunity to get a backup of everything I was worried about–I had one anyway, but “fresh full backup” is to my mind more useful, or at least less hassle, than “old full backup plus many many many incremental changes”.)
And then last night I was reorganizing my office, and I turned off the computer so that I could unplug and rearrange the cords and the UPS[1] and everything connected one way or another to the wall sockets, and it wouldn’t turn back on. (It’s not the UPS or the socket, either. Tried different power cords, different sockets known to work, everything.)
It’s not the power supply, which would be an easy fix, and given that the computer in question is six years old, a replacement is not unreasonable. In the meantime, everything will be fine, it’s just a bit odd to be dealing with everything online and not using my desktop.
(Plus I really miss my Fallout: New Vegas games, dammit.)
