What could I be doing wrong? Hang and crash at heavy game load.

Hey, Neb here.

Here are my specs:
CM 690 II Advanced case with FULL fan system, in good directional array and airflow.
MSI MS-7522 mobo
Socket 1366 Intel i7 920 CPU
Radeon HD 5770 (I have a Gigabyte SOC, and I have tried single card and 2 way crossfire [with a sapphire 5770], no difference at all)
Corsair 3x2GB High Performance RAM
500g WD standard HDD
Apevia 680w Standard Non-Modular PSU
(Addons below)
Corsair H100i Liquid CPU cooler
Full set of Cooler Master Blue series varied-size fans.

I've been building up this specific rig with upgrades one-by-one for a while. Just yesterday, i bought a GTX 760 GPU and had no issues hooking up, getting drivers and stress testing. I am a very happy guy with this card.

As soon as I opened Crysis 2 and started up the gameplay, though, i got a hang and crash. The computer turned on and off a couple times, then started and ran like normal. My question is - what in this system could be interfering with the card, or causing the PSU troubles?

I did a calculation of PSU power at full 100% load on everything, and I ran well at 545w on a simulator, over 100 below what my PSU supports, so i doubt it would be my psu. Though I am open to ideas.

Otherwise, the only odd thing I could think of is that my PSU only had two 6-pin male ports, so I had to do some heavy adaption to get the correct ports for a 6-pin 8-pin GPU. I don't think this could be the issue though because to prevent maxing, i adapted the two 6's to an 8 and two hard drive connections into a 6.

If anyone has any input, it would be much appreciated. Thanks and cheers!

-EDIT-
I checked around at several pages in Event Viewer and nothing came up to be conclusive.

How does it run on other games? Is it OK or is it just Crysis 2 that causes you problems?

Did you clean all your AMD drivers? They could be conflicting big time as you've changed from AMD to Nvidia. Try using a program called Driver Fusion and clean all your graphics drivers, reboot, reinstall the Nvidia ones (and do a clean install of these too to make sure! select "advanced" or "custom" install, can't remember which one and you can select through there to do a clean install) and give it a try.

I kept the AMD drivers on in case I needed to quickly swap back, then forgot about them. Thank you for the input on that!

Also, i'm going to be trying out some new games, but first I just wanted to confirm that these hangs won't damage my system.

Be right back.

Okay, I've done a bunch of resetting and clearing drivers, and the problem persists. I also tried Borderlands 2 and BF3 and I still get an error with both.
