Ok so I just built a new pc about 2 weeks ago.
Until today I was able to play any game without any problem but now games keep closing on me.
First it happened with Left 4 Dead and I thought that maybe was something wrong with the installation.
After I played Company of Heroes and after a few minutes of playing I got BSOD.
Tried again and same result and now Lord of the Rings Online keeps closing after a few minutes.
I really don't know what to do.
Any help would be appreciated.


Here are my specs:

- Western Digital Caviar Black 1TB (7200RPM / 64MB Cache / Sata 6Gb/s)
- Corsair PowerSupply CX V2 600W
- Gigabyte GA Z77X UD3H
- Intel i5 3570k
- Asus Geforce GTX 550 ti top
- Corsair XMS3 Vengeance 8GB DDR3 PC3-12800 1600MHz (2x4GB)
- Windows 7 64-bit

I've got no overclocking on so that's not the problem.
And heat is not the problem either. I cheked and it was normal.
If it would've been heat then it would've crashed 1 week ago too.
It's quite strange that I was able to play FIFA for about 2 hours but when I tried to start another game I got a blue screen and the pc restarted.
I'll run the tests tomorrow and post the results.

I download HwMonitor and installed it and the temperatures are okay except the processor's.
It ranges from 27 degrees to 40 when not doing anything on the pc.
Would adding some more cooling paste solve the problem? Or should I add another fan on the CPU cooler?

I've reinstalled the gpu drivers but that didn't solve the problem so I ran a memtest.
At 42% it already found like 840 000 errors and it's still running at the moment.
Guess that means new RAM right?

one more question though
would these ones be a good replacement? Corsair XMS3 Vengeance 8GB DDR3 PC3-15000 1866MHz (CMZ8GX3M2A1866C9B) (2x4GB)
the mobo has no support for 1866MHz altough there a few 1866MHz models named on the memory support list
