Issues Running Games, Help Please....

[Bleedblue12345]

Hi everyone, I am having several issues running a few games.

Mainly these games are:
Race driver GRID demo
UT3 Full version
Colin Mcrae DIRT Demo
a few others...

Specs:
Q6600
Vista Ultimate 64-bit (fully patched, SP1, etc.)
8800gt (700/1000) with latest beta drivers
4gb ddr2 800 ram
ASUS p5k Deluxe with latest BIOS and firmware.
X-fi XtremeMusic with latest drivers.

I run all my games in ADMIN mode, and I tried compatiblity mode for all my games, nothing works.

RACE DRIVER GRID: Start it up, get to the splah screen, and it sits there forever.
UT3: starts up splash screen and sits
DIRT: Starts up splash screen, goes to black screen, sits...


This is really frustrating.

Edit: I have tried disabling all anti-virus and other processes, nothing helps.

Thanks

you're sure your system is stable?
what benchmarks/torture tests have you run?
have you tried stock settings?

System is 100% stable through prime 95 for 18 hours......

Memtest runs fine...

all other games run fine for hours (crysis, halo, SupCom, etc.)

I had that problem with a few games when I first built my computer.. I turned off UAC then ran each one fine. Enabled UAC again, then restarted and everything kept working... If you haven't tried it without UAC, you might as well?
