Vista Crashes coming out of sleep when UAC is enabled.

[tuckers]

I have had this bug for six months and looked everywhere for a solution to, but to no avail.

I have a Vista Ultimate 32 system. I have rebuilt it from scratch several times, and have used three different graphics cards (though all were nvidia), I have searched far and wide for a solution. So far nothing. This problem shows up even on a freshly formatted and installed system with no added software and minimal driver installs.

If I have User Account Control enabled, about 50% of the time when my system comes out of sleep, my screen and system will freeze after it is on for about 15 to 20 seconds. Sometimes I will get a UAC authorization pop-up for a driver or system tray item, and when I click the allow, it freezes. Sometimes it just freezes when coming out of sleep. There is nothing in the Event logs except a something stating that the system unexpectedly shut down.

If I disable UAC my system runs fine.

But since I use a lot of P2P programs, I need to use UAC, and I believe that UAC does really increase security of Vista.

Any ideas of how to fix this?
