Hello! I have a kinda weird problem with my PC.

Everything started couple of days ago when I was playing games ( Dota 2 to be accurate. its pretty much all i play), and suddenly my both screens went black (Never bluescreen). PC stays on but all activity dies. Cant hear anyone in Skype / teamspeak, nor can they hear me. All i can do is to force shutdown from the power button. Since that it happens whenever i go play Dota and it only takes 5mins-15mins to crash my PC. I have checked my Temps, and CPU is around 40'c while GPU is running around 55-60'c. I couldn't make my PC crash with 3DMark firestrike, which i find kinda weird. Unfortunately "Whocrashed" doesn't tell me anything.

Here is my specs:
Crosshair III Formula, AM3, 790FX
Phenom II X6 1090T Black Edition, AM3, 3.2GHz
XFX Radeon 280X DD Black
HyperX 4x2GB, DDR3 1333MHz
PSU i cant tell anything about because I got it from my friend for free and it has no labels on it. Prolly some bad old PSU around 400W. Have been playing with this PSU for 13months now without problem.

Also, heres an imgur from my HWMonitor http://i.imgur.com/YsdypTt.jpg

I hope you could help me out so I would have a clue which hardware to replace first.

Thanking you guys already!

Edit1: Heres a very quick video I filmed to show how it happens, if it matters

And smack your friend in the head for letting you use this mystery power supply even for free. Friends don't let friends use bad power supplies.
Going by what you have posted, replace the power supply, you are risking your whole system running an unknown power supply if you don't know the brand, model or ever wattage on it.

If that does not fix things, test the video card in another computer that can run it.
