I recently Installed Windows Vista Ultimate 32-bit with SP1. Everytihng works fine except when i try to turn off PC, before it's turned off, i get Blue screen that doesn't say anything and then after 3-4 seconds PC restart's. I can only use Power button to turn it off (that will damage hard disk). When i turn it back on, i get this massage from windows:
"Windows has recovered from unexpected shutdown"

When i click details i get this:
Problem signature:

When i go to Minidump i get some wierd letter's that don't mean anything, and i can't copy that here because it's too long and my PC freeze's.
And when i go to "C:\Users\Srdjan\AppData\Local\Temp\WER9E62.tmp.version.txt"
i get this:

Windows NT Version 6.0 Build: 6001 Service Pack 1

BuildString: 6001.18000.x86fre.longhorn_rtm.080118-1840

And when i go to "C:\Users\Srdjan\AppData\Local\Temp\WER9E62.tmp.version.txt"
there i get some very very long text that i don't know what it means.

Im not sure but i think i didnt get this before i installed sp1 for Windows Vista.

Question: When you shut down do you have USB devices attached? If so, unplug your USB devices just prior to shut-down and tell us if your issues persist..

I don't have any USB devices attached, and problem still continues.
