Infuriating issues with my new system, please help!

I have been sitting in front of this piece of **** for 12 hours straight trying to figure out why my new system keeps blue screen and getting graphic corruptions. The driver "nvlddmkm.sys" will either crash and recover, or crash and blue screen. This will happen randomly. It could happen while its just sitting idle. It happens quicker if there is a load on the video card (watching videos or playing games).

Here are my system specs:
EVGA Nforce 780i SLI motherboard
EVGA Geforce 9600gt 512mb
BFG 650watt power supply
OCZ Reaper DDR2 800 ram 4GB (2x 2GB)
Sound Blaster X-Fi Pro
Antec NineHundred Case
500GB Western Digital SATA HDD
Lite-On cd/dvd combo drive


From what I've read, the following would be the problem....and at this rate, I might as well just buy another ******* system.

1) power supply not providing enough voltage to run system
2) bad ram
3) bad video card
4) bad motherboard
5) nvidia just sucks and their video drivers are made by monkeys


I really don't have the kind of money to blow on trouble shooting this **** thing so can someone please give me some advice on this?

Thanks.

btw...this is the first (and last) time I have gone with a full nvidia system. I've always been an ATI fan....and now I know why.

If you swap out the video card does it stop?

I found out that one of my friends has a computer that has PCI-E slots. (Not may of my friends are into computers so I was freaking out last night).

We tested my card in his system and it artifacted on his system like it did on mine. I also tried his card in my system and it started up just fine.

I will be ordering the 8800GT as a replacement for the 9600GT as well a bigger PSU (850 watts).

I'll post back when the parts come in.
