Ok community listen up. I got hold of a gtx 660 which I just installed (gigabyte windforce oc edition) in one of my two pcs. I get driver crashes after 10-20 minutes of gaming or after a few minutes of stress-testing. The crash is of the type: 'The NVIDIA OpenGL driver lost connection....error 7). After trying quite a few things (drivers clean install with driver sweeper etc) I decided to perform a fresh windows 7 install. Now here is the weird part:
After windows 7 installation was completed I installed only the necessary drivers to be able run MSI afterburner in conjunction with Kombastor burn-in mode in order to stress test the gpu. My two computers are next to each other. So, I started stress testing the the new gpu on pc1 while I was writing an email on pc2 (which has a gtx 580). All of a sudden, after 5 minutes or so, both pcs driver-crashed AT THE SAME TIME!. The pc2 (with the old gpu, gtx 580) crashed saying drivers stopped responding.
PC1:
Asus extreme-z z68
i7 2600k @4.5ghz
4gb corsair xms3
samsung 840 ssd
a couple of sata storage disks
xh1000 corsair psu
PC2:
Asus p8z77 deluxe
i3 2100
4gb crucial generic ram
samsung 840 ssd
HX750 corsair psu
I think that 2 pcs crashing at the same time might suggest some power instability in the electrical wiring of my house.
On the other hand I tested the gtx 660 on another new build with a 450w power supply (xfx pro) and an i3 2100 for 30min++ with afterburner/kombustor burn-in and it didn't crash.
I am not a pc noob, in fact I am a pc builder and I have never encountered such a problem before. I've built 20 pcs++
Please any idea is welcome!
Regards
