Hello everyone!

I made a totally new PC:
Hardware/software:
SSD: Samsung Pro 840 120GB (Win7 64 bit - without updates)
VGA: Sapphire HD7850 2GB OC (Catalyst: 12.10)
MB: Asus M5A99X EVO R2.0 (BIOS 1201)
CPU: AMD FX-6300
PSU: Corsair GS600W 2013 Edition
RAM: Corsair DDR 1600Mhz
I use HDMI cable, i have stock options nearly everywhere.

When i play (Team Fortress2; CS:GO; FarCry3) i get frozen after 3-30min. Sound stucks, monitor don't receive signal. PC tries to auto-restart, but can't. My Mobo shows that there is some problem with the VGA (i get red led).
After I manually restart the system, everything is fine.
I tried to plug/unplug everything, latest drivers, other PCI-e cable, BIOS settings about voltages. Nothing changed it. I tried the card about an hour in my other PC there was no error.

Please help me find the source of the problem, and get rid of it!

Did you overclock anythig yourself?

Did you try prime95 to see if your system is stable?

Did you try momitoring your system temperatres during your gaming? Or stress?
