BSOD, cannot reboot xp or load vista

[-Sn1PeR-]

I'm having serious issues with my new computer. I have successfully installed windows xp, and downloaded all of the updates... when I reboot I get a BSOD with a IRQ_NOT_LESS_OR_EQUAL_TO error 0x000001A8 0x00000006, 0x0000001, 0xF748F18B
and something about nvgts.sys. I can reinstall over the current install and reboot for a while, but eventually it crashes (normally BSOD after first restart). Additionally, this BSOD occurs if I boot Half-Life2 (when I am in windows long enough to install it and try to run it) . I have formatted/installed about 7 times now, and cannot get passed this BSOD. At one point I was able to get Win XP x64 to install and play In the Company of Heros just fine for a while (but no Wifi drivers for my Linksys WMG54 card).

So I try to install Vista x64 Ultimate, and get the same BSOD when the installer reboots, but it doesn't stay up long enough to copy down the numbers.

So basically I cannot get any version of windows OS to install and stay up.

Any help would be great... I'm thinking it's a hardware issue, so am trying to get a hold of some friends w/ compatible hardware to swap stuff out one at a time.

MSI P7N Platinum
XFX 8800GT
Q6600 g0
2x2GB GSkill DDR2 800
250GB Maxtor SATA drive

What a waste of 14 hours...

My friends recommended:

a) removing 2GB of ram for a total of 2GB, tried that and it didn't work
b) upping the RAM voltage. The sticker on the side says 1.8-1.9V, and BIOS states that they are running at 1.9V, but I cannot figure out how to change this.

I'm starting to get worried that I won't be able to find the faulty hardware before my RMA time is up from Newegg/clubit.

It's the RAM, either the timings or bad sticks. I borrowed some OCZ RAM and it works like a charm!
