Computer freezes up during gaming

Hey what's up, just built a new system about a week ago and all seemed well until I started using it for its intended purpose....gaming.

Turned on Bad Company and everything ran pretty good for about an hour or so when the screen froze up and the last sound heard kept repeating. Figured it was a game glitch so I restarted my PC and gave it another go only this time I had RealTemp, SIW and the MSI Afterburner (with logging enabled) running thinking that maybe my GPU was overheating. Again, it ran great for about 30 minutes this time before freezing up. I restarted and pulled up the log and saw that the temps for the GPU never went past 69c and the average GPU usage was around 80% give or take. Also, I've ran Prime95 several times on my PC and the temps never went above 55c so I know it isn't the CPU overheating. I can have my PC on for hours doing normal every day tasks and it's fine, no freeze ups, glitches or whatever. My thoughts are that my PSU isn't able to handle wattage needs and that it's shutting down. I have no way to prove this which is why I'm posting on here in the hopes that someone can help me fix the problem so I can play BF3 for hours on in when it comes out lol.

System specs are

Win7 Ultimate 64x
Cooler Master HAF X Tower
x2 4Gb G.Skill 1600Mhz RAM
Corsair 750w PSU
Intel I7 2600K
64Gb Kingston SSD
XSPC CPU water cooling

Any advice/help would be greatly appreciated.

Just realized I didn't put the video card in the system specs lol. I have a 2Gb MSI R6970 Lighting

For those that might look at this and say "hey, i have the same problem", i've figured out what was the problem.

I bought 1866Mhz RAM rather than the 1600mhz as I mentioned above. When i looked at my RAM closer I noticed this. Well in my BIOS it said 1600mhz at 1.65v. Looked up the specs for my RAM and the voltage should be at 1.5v. Switched over to the AI tweak i believe and changed the memory speed from auto to XMP which made my memory go from 1600 to 1866 and from 1.65v to 1.5. Played BF for two hours straight without any issues so this has resolved the issue thus far. Thought I'd post this up in case anyone has the same issues.

Glad you sorted it out! That can be kind of frustrating when a program pushes your RAM where its voltages are unstable. The 1.65v to 1.5v is very common.
