Hi guys! I am having a problem with my new pc.
Spec's are:
MOBO: GA-970A-DS3P
CPU: AMD FX 6300
GPU: ASUS R7 260X OC EDITION 1 Gb DDR5
RAM:2x MUSHKIN 992029 DIMM 2GB DDR3-1600 ESSENTIALS SERIES
PSU:Inter Tech 550W

The problem is that when pc is running and uses much of its RAM, for example during a game or during multitasking, the screen will turn to black and thats it, there's nothing I can do after that other than restart.
It happened many time during alt+tab when I was playing a game, and screen went black.
It also happened when I opened a program (and permition message should pop up) and then black again.
I thought that it could be due to low RAM, I dont know I just make an assumption.
I also copied the events around the time when the problem occured.
Thanks you in advance!!

Yes I buidled the PC by myself, but I believe that it's not that since I had "pushed" the power consumption by overclocking the GPU pretty much without any problem.

P.S. The PC isn't shutting down, only the screen goes black and that is happening only during alt+tab during game (on fullscreen mode) or when it's going to open an other program and going to ask permission and all theese times RAM was pretty much Loaded 65+%
