Hello Gafs.
I have recently built a new rig and only migrated the GTX670 from the old six yeas old rig. The card was purchased last year and it worked fine on my old rig, but it started to fail in about two weeks after I put it in my new rig. It's totally fine only if I just use it without running any software requiring 3D acceleration including all the modern browsers, windows 8 explorer.exe, video player, and you know, games.
It's probably not driver's fault since I clean installed at least 6 different versions of drivers including the good olde 314.22, and they all crashed when hardware acceleration kicks in. I can reproducing this 100% by booting -> login windows -> doubleclick a 1080p video on my desktop and then 10 sec later I'll have a wall of nvlddmkm errors, system slow down, shutters, and then black screen, sometimes reboot itself. I mean, this IS a video card error, right? Since the memtest came back clean, all versions of driver not helping, flashing bios doesn't seem to increase stability also...
Please share the wisdom
I haven't built pc for a very long time....
