Could use some help troubleshooting!

Ok well about 2 weeks ago my MSI HD6950 Twin Frozr III unlocked to a 6970 fired electricity out of the side of my HAF 922 I got my RMA number from MSI but have not mailed it out yet. Needless to say I was not amused at all. Since it is almost tax time the wifey said I could use her video card which is the exact same card except it did not unlock.

I plan to order a new 7950 or 7970 and a new power supply & SSD but if it screwed up something else in the PC I wish i had a way to find out so I can forgo getting the SSD and replace whatever is screwed up.

I of course was scared that it may have screwed up something else but to my delight it booted back up with the wifey's card first try with no problems. Now to the problem at hand, I have been experiencing random shut downs with no real way to pinpoint the problem. It is like the computer loses power unexpectedly, no BSOD or .dmp file or anything. I was leaning towards it being the power supply thinking maybe it actually took the video card out or something but just before posting this I ran the CPU Linpac for 1 hour and the power supply test for 1 hour on O.C.C.T. Without it shutting down. So far the computer has shutdown once during a game, Kerbal Space Program, 2 times while on Youtube, and once like 4 seconds after starting a video on PotPlayer. Note that I have watched 20 other vids on Youtube and played Far Cry 3, Assassin's Creed 3, Fallout 3, and watched multiple vids on PotPlayer without it shutting down. It seems so random I am just not sure what to do. I can say the +12 on the Power Supply drops down to 11.73 during the O.C.C.T. power supply test. If you guys are fairly sure that it is the power supply then any idea why it don't just shut down instantly when I apply so much load to it?

I have had this PC and built it myself the beginning of February 2012 and have never ever had a problem with it til the video card went crispy on me. One other thing I almost forgot is the last couple days I have had the mouse pointer 2 or 3 times just freeze, it will seem like the whole PC locked up because nothing responds but then 15 - 20 seconds later it just comes back like nothing happened and I also get no event log for that either. I am going to be beyond mad if it did something to my Crosshair V but I guess this is the best time of year for that to happen when you are on as tight of a budget as I am. If you guys think the power supply might take out some other component or something let me know and I guess I will just turn the damn thing off til I get new stuff.

FX-6100 OCed to 4.515 Ghz

Crosshair V Mobo

COOLER MASTER eXtreme Power Plus 700 Watt

8GB Gskill 1866 4GB x 2 @ 9-10-9-28

2 x Seagate Barracuda ST500DM002 500GB in Raid 0

Corsair M60 Mouse

Sidewinder 4 Keyboard

I also ran Malwarebytes and an online scanner and MSE and found nothing on the PC. All temperatures are exactly the same as they have been since February except my wife's gpu runs cooler than my fried one did.

Sorry so long was hoping not to miss any relevant info and thanks so much in advance!

Try a different powersupply for like a week, that is what I would do.

I did think about it but the only other one in the house that has enough power is modular and the wires are way way too short to reach anything in my HAF 922. PC gaming in this town is rather rare so no buddies I can borrow from either. I of course can order a new one when I get my taxes back and was going to anyway but I would like it if there was a way to narrow down the problem before so I don't buy something that I did not have to have right now and wind up with another part that needs replaced instead. Also those voltages on the PSU have been like that since I bought the PC, in Windows it shows 11.73 on the +12 but in the bios the motherboard monitor shows it well over 12.
