Computer Randomly Restarts

The issues started after my PSU blew out and I replace it with a new one, the computer will restart or shutdown without turning on again by itself when I play games such as: World at War, MW2 or CS:GO, but not when I play Garry's Mod or CS:S. Now, I was told in a post on the steam community that the problem lied with the BIOS not being compatible with the applications, so I updated it to the latest version but the problems continue.

I've checked the CPU temps when games are not running and when they are, all under 40 degrees.

My thoughts were that I may have not correctly installed my PSU, but then again it should restart without a game.

As you can guess this is very frustrating and I need to get this solved as its been about 2 months now with the problem without any solution.

PC Specs:
- AMD FX-4170 Quad-Core 4.2 GHz
- 8GB DDR3 RAM
- Windows 8 64 Bit
- GTX 660 EVGA
- GA-78LMT-USB3 - F4

I thank you before hand, Chris.

My simplest advice would be to double check the PSU connection, and that the PSU is both pushing enough wattage for your setup, and is not faulty in some way.

I've had the restarting problem several times before, and it was always either due to CPU overheating problems, or PSU issues. Especially under load (ergo while playing demanding games).

I've unplugged the reset button, will that be the cause?
Also, the PSU makes some weird vibration and noises.

Well yes and no. It doesn't work like that though. When you're buying a PSU, it has to cover the maximum amount of wattage your setup requires. Say your PC needs 400W or so you get a 450-500W+ just to be safe, and so on. So IF the PSU is really failing to push enough juice with more demanding games, then it is possible that it simply doesn't have the power you need. But that's not the only possibility, because it could also be that the PSU is faulty and therefore causing issues regardless.

There are a lot of tutorials/threads/calculators on the web that can give you a near accurate range of the wattage you need, based on your hardware, if you're not entirely sure that is.

The PSU I had before was a 550w also and worked fine until the summer when it overheated and poped, as I suspect.
Im going to get a 550W XFX .

UPDATE:
Question: I have a 6-Pin coming out of my PSU into my graphics card and a 4-Pin going into my 12v atx. So I though, if a 4-Pin is outputting 8v wouldn't 6-pin output 12v? So I unplugged the 4-Pin and the 6-Pin and plugged it into the 12v and left the 4-Pin connected to nothing and used a spare molex to power the graphics card, however this didnt even turn the computer on, why is this?
