Windows apocalypse

As a follow-up to my hard drive terror I guess I'm now in a full-blown Windows apocalypse. I was fairly sure it was the power supply crapping out on me and it was only crashing during the night, so I was waiting till this week to get a new one. Then yesterday it rebooted in the middle of doing something. Then would only give me an "lsass.exe - System Error Object Name not found" error and reboot when I hit OK. Much research and fiddling hasn't righted things so I think my Windows is just toast.

Anyway if I'm extra slow to answer your emails that is why.
