The last thing I did yesterday was install Power Point. Suddenly the computer started getting all kinds of weird problems and when I tried to reboot everything came to an end. For a while it didn't look like even the system restore disks were going to bring it back.
I have backups this time, but I lost about 30 mp3 albums that I hadn't backed up yet. Other than that, it's just the major pain that this kind of thing always is.
