Hello! A few days ago I posted on few other forums about my problem with new GTX 960. http://www.tomshardware.co.uk/answers/id-2581724/gtx-960-driver-error.html
Many people suggested to RMA the card. I did that yesterday ant today they told me that they tested everything and it works just perfectly for them with no issues. So they gave me the same card back. Now I'm completely lost and have no idea what is wrong. The same problem continues... While doing nothing, everything works fine, some games also run fine. But when it comes to high load (demanding games or stress tests) the screen just turns black and comes back to life with the same error:
No such problems with my old GTX 560...
Something's wrong with my hardware? Does anybody have any ideas? Thank you in advance!
My specs:
Gigabyte GeForce GTX 960 OC
AMD FX-4350 QUAD 4.20GHz
DDR3 Kingston HyperX Beast 8GB (2x4GB) 1600MHz CL9 1.65V
ASUS M5A97 LE R2.0 Motherboard
1TB HDD
Corsair CX600 600W PSU
Windows 8.1 64-bit
