Damnit Not Again

My computer is broken.

Again.

It's the same thing that happened last time, total blackout, only a sharp wailing when I try to boot it. It would make sense if something actively bad had happened, but all I did recently was open it up and clean out the CPU fan, so only getting the overheating alarm makes no sense. I'm going to open it again and try to figure it out, but I really don't know.

Last time it fixed itself though, so I'm not too worried.

Yet.
