Hi everone,

I hope you can help me with that.

My PC
I7 3820
Asus P9X79
G-Skill Ares 1600 CL-9-9-9-24 1.5v 4*4 GB
Asus GTX 670 Direct CU II (Stock frequency)
Antec 850 True Power Quarto (Bronze)
Crucial 240 GB M550
WD 2TB Green

As you can see all specs are on ideal frequencies and I never did overclock, nut suddenly the PC going nuts.

games not run or crash then windows itself crashed and BSODs with no reason.

I tried
Swap Vga with GTS 450
Swap Rams with Corsair Vengeance 8GB 1333 and Kingston 2 GB 1333
Swap PSU with Corsair TX650W
Remove SSD and then HDD and SSD together.

even install my Ram and VGA on another AMD system (and worked fine with Prime95 and Furmark but ram runs on 1333mhz)

Furmark works fine alone or with Memetest 86 but when run Prime95 with it then BSOD.

Can you help me with suggestions or what is the source of the problem because I am afraid to buy new PSU or CPU or Board and boun the problem was with another hardware.

Waiting for your replies and many thanks in advance for your help.
