Computer reboots while gaming

Hey guys,

I've been having this problem for over 8 months now, and yes, I've been lazy about fixing it, which is probably a horrible thing to admit.

My computer tends to shutdown and reboot itself while I'm playing games (and only during games,) whether it be a first person shooter, MMORPG, MOBA, or flight combat sims. It'll happen about an hour to two hours into gameplay (give or take.) My rig is 3 years old, but this problem didn't start until about 8-10 months ago. First, I suspected my video card, but it's seated properly, the fan's running, and it seems to be working properly. I disconnected all the power supply cables from the components and redistributed them so my hard drives and such weren't feeding off the same line. But still, nada. At the beginning of the year, I bought a second GPU (same as my first) so I can utilize SLI. I didn't expect this to alleviate my situation, but it hasn't made it worse.

Last month, I had a hunch that it might the wall socket. When I removed the face plate and took out the socket, I found that the previous tenant installed a 3-prong outlet to a wall socket without a ground wire. Geez! So I got a heavy duty extension cord and plugged my surge protector to an outlet that I confirmed was grounded. Hoping this would resolve my problem, I started playing some Wolfenstein. Unfortunately, I suck at that game and about 40 minutes in, I got tired of dying and quit. I didn't have time to play games since then until this weekend when I downloaded Archeage Beta. About 45 minutes into it, I noticed that my rig was blowing out really warm air, but I figured it'd be okay. About two hours in, *blank*... my computer shut itself down without notice and rebooted itself. It did that again an hour later while I continued to play Archeage. Today, I left my temperature monitoring software up on my second monitor while playing Archeage. About 2 hours into it, my main GPU was at around 68C, secondary was at 63-64C, and the CPU at around 64C. Then, in the middle of a fight, *blank*.

I'm going to go disconnect everything and check my power supply unit (not that I'd know what I'm looking for,) but if you guys have any suggestions on how I could narrow down the cause of this problem, I'd appreciate it.

System Specs:
Intel i7-2700K (at stock speed, 3.4GHz)
8GB RAM
SSD (O/S drive)
1TB HDD (7200RPM? Main storage/software drive)
500GB HDD (7200RPM, Secondary storage drive)
MSI N560GTX-TI Twin Frozr II/OC Fermi x2 (SLI)
Corsair TX Series 750W 80 Plus Bronze Certified
Window 7 SP1 64-bit

(Let me know if you need any further information.)

Also... is there a way to ground the socket at my computer desk so I don't have to run power over an extension cord?

Thank you all in advance!

Uh... I might have to test it further, but I think I found the cause of the problem. ... It's embarrassing.

So, the PSU... I installed it upside down and the fan was facing the bottom of the chassis. I guess it was overheating and shorting out? Luckily, I don't think there's been any hardware damage. I've played a couple of games and my computer hasn't had any instant shutdown/reboot.

Not sure how I missed that to begin with... guess it's one of those "so obvious, you don't notice it" kind of things. I caught it while looking for the model number for the PSU. Huh.

Anyway. For now, I'll say this is solved.

Thanks for your response, Scout!

Have you gotten any BSOD at all lately?
If you haven't you might need to replace your PSU. Its not the actual wattage, its the PSU itself. Replacing it would most likely help. If you have any other system, you can always test each part(CPU, GPU, RAM) in a different system and see if you get the same problem.
But again its most likely your PSU if your not getting any Blue Screens Of Death.

EDIT; Remembered something that happens with my laptop. Has your system ever started beeping on startup? If so what is the motherboard model?
