Hi everyone! I have built new PC recently with following configuration:
- CPU - Intel core i5 4670
- MOBO - gigabyte ga-h87-d3h
- RAM - g.skill sniper series 8gb (2x4gb)
- GPU - gigabyte geforce gtx 760 oc 2gb rev.2.0
- PSU- xfx pro series 650w
- Case - cooler master had 912 advanced

OK, so problem starts when I bought videocard , before that was using CPU integrated. Sometimes PC just freezes and only hard reset can help. This happens very randomly: sometimes just after system start, sometimes after few hours of working. It may happen on random circumstances: whether I play game or just working in text editor.

Also my system is Windows 7 64bit service pack 1. I have launched windows memory diagnostic tool which is provided by default on windows, it said that there are no errors.

May it be connected with video card? All components are brand new, only 2 weeks since I've bought them and I'm still testing my configuration on some games and all of them are pretty fine except one - far cry 3 where I experienced some artifacts.

Would be appreciated to hear some advises from you, folks, and thank you for your time☺:)
