Vista Died!!???

Vista upped and died on me yesterday. The symptom was, a screen from Dell Direct Media splashed onscreen, then Windows boot shut down to "protect your system". Gosh... Denial of service really does protect my system all right.

I ran the diagnostic tools and everything passed, so I tried to reinstall Windows from OEM dvd's, and failing that, I installed Ubuntu. Still have 90% of a working computer, I guess.

Very disappointed.
