Hi,
my PC's specs are:
-ASUS GeForce GTX 680 2GB PhysX CUDA
-Intel Core i7-3930K Processor
-16 Gb RAM DDR3 Corsair XMS3 2000MHz
-1200W Silent Pro Gold Cooler Master
-ASUS RAMPAGE IV EXTREME, Socket-2011

My drivers are all up to date.
I have had this problem for some time now (mabye 2-3 months) and I can't find out what the problem is.
When i did bye it there where no problems at all, I could play all from minecraft too Battlefield 3.
Sometimes I can play for hours and other times just some min and then it completely shuts down.

Some one that know's what is up with this??

How old is your PSU?
What has changed in the last 2 to 3 months?

The PSU should have enough power to run your system, unless it's an old one so that the capacitors went.
Do you have a killameter that measure power draw from the wall?

My PSU are 1 year old.
The change is, it did not turn it self off before 2-3 months.
No I don't have a killameter.

The most likely cause in random shutdown cases is PSU-related issues.

The CoolerMaster 1200 has issues with ripple on the 12V rail under some circumstances. Maybe you are running into that. The only way to know for sure (without guessing and doing parts-swapping) would be to hook it up to an oscilloscope and look at what shows up when it randomly restarts.
