Brand new rig I just built, AMD X2 6000+ water cooled, ASUS Crosshair, Mushkin 2X2GB DDR2-800 4-3-3-10 2T, EVGA 8800 Ultra Superclocked, Thermaltake ToughPower 1200W PSU.

Vista will just randomly lock up, completely freezing. Reinstalled Vista twice already, making sure to only install Vista security updates and hiding drivers for the rest of my system and dl'ing them through nvidia/ASUS.

Ran Memtest (windows version) for a few hours yesterday without a hitch. Then closed both instances of that and ran Orthos blend stress test which ran for a few hours fine so I left it on and went to bed. Got up and my monitor was in sleep mode and my pc was still running but nobody was home, locked up again. Wondering if I should disable the nvidia RAID drivers from startup (it's hardware RAID, do I really need software?).

The other issue I have is ASUS Probe2 reporting a lot of my voltages at 4.08v, but I just think the program is FUBAR. My motherboard temps report an average of 49c which is hot (my cpu reaches 35c max after hours of stress testing) and I have my memory and cpu settings/voltages set manually in my BIOS (which is most recent BIOS for my motherboard). Been running DOS memtest86 without a hitch for over 3 hours now. Also turned off indexing of my hdd's.

That about covers it! Any help would be greatly appreciated!

Almost 10 hours of Memtest86 DOS stable now....

Still no ideas? Ran driver cleaner and installed all new drivers, nVidia beta 169.04 is the best display driver yet but still get freezes. Beginning to wonder if I possibly have a dying HDD because my pc locks up halfway through HD Tune error check. My memory(Geil Esoteria 2GB) tests fine through DOS Memtest even clocked up to DDR2 950 4-4-4-12 @2.2v.

You are not the only one. I also have random hangs (no BS) even with(out!) all recent OR old drivers (of every hardware!) in EVEN 32 or 64 bits version. Take a look in de admin tools for the logfiles and you'll find 2 main problems (I don't have the details with me now, somthing about Http and something about a security pack kerberos that is NOT needed in Vista).

Clicking on those redirects you to a knowledge base of MS wit all sorts of comments of user having exact the same experiences driving everyone crazy. Before that all my NEW hardware had been exchanged and still it exists.

MS seems to ignore all those uses and even tells to ignore these logfiles / error ("LOL", ignoring an error!) but most of those users even have the newest hardware!
