::*I have a dual booting system with Vista Ultimate x64 and
Windows XP x64.

In XPx64 I can have multiple games running at the same time in windowed
mode and much much more.

For this example I have two WoW clients open in windowed mode full
detail @ 1680x1050 and ventrilo and multiple firefox's open along with
music playing and a file being coverted to mp4 format. This will work
flawlessly nothing crashes nothing locks up nothing does anything wrong.

Soon as I go into VUx64 and do the same exact thing the computer will
work for a bit. Then I will notice the mouse twitch and it is as if my
computer is a locomotive on the railroad going 60mph and suddenly
slamming on the breaks and slowly grinds to a halt. When it does stop
responding the sound that was playing keeps playing and does not repeat
or seem to not work correctly it is like only the GUI stops responding
completely but the subsystems of windows keep working. Though I cannot
recover from this as I have to hardboot the system to have any
functionality besides listening to music.

I have the most up to date nvidia drivers for the mobo and the release
drivers from the nvidia site for my video cards. 169.25 (or something
close to that they're currently at Nvidia.com)

Everything is up to date and what not.

I have everest running most of the time and I did notice that the
second video card in the setup. That is the card in the SLi setup that
does not have the monitor hooked to it. Is 20c hotter than the first
card the one that actually outputs the video to the monitor.

In XPx64 I have everest running as well and the second card never EVER
exceeds the first cards temp.... even in games... Crysis, CoD4, TF2,
HL2, WoW etc etc etc

Here is the setup

Q6600 @ 2.4GHz (default)
4GBs G.Skill ddr2 5 5 5 15 2t @ 1000-1100 mhz. Though I run this at
800
Evga 680i SLi
Evga 8800gtx SC x2 in SLi
X-Fi Xtrememusic (PCi)
DRU-800a (dvd)
raid 0 (stripe) Western Digital Caviar SE16 WD3200AAKS 320GB (OEM)
ABS 1300W PSU (I should have bought a freaking Ultra)

I have ran memtest for hours and prime95 in XPx64 & VUx64 for about 8
hours a piece.

I am thinking that the lockups in Vista are totally related to drivers.
Most likely a combination of SLi and current vista drivers? I have
installed all of the critical updates from nvidia.com and anything I
could find from windowsupdate.

I can run Crysis in XPx64 without crashing for hours on end. The funny
thing is as soon as I start Crysis up and load a level it is only a
minute or more before it does the same thing as with two WoW clients
running in VUx64. This is very frustrating as I have purchased this to
use it not to be held back by it =)

I am sure this is long winded and may even be covered in another thread
and or this could be the wrong area to post this. If so please tell me
as I am at work and didn't have but a moment to write this and skim over
the rest of the threads.

Thank you in advance.
