I'm coming here to Tom's Hardware to solve a problem that I'm stuggling with for over half a year, since I've built this computer. I went for Gigabyte GTX760 rev 2.0, it's running all the games that I need quite smoothly but problem is that it keeps crashing on my Windows desktop. I mean that I quite frequently get the several second freeze and then a "Display driver has stopped responding and recovered successfully" message. Sometimes I spend 3 days without a single of these things, sometimes I come home and need to keep restarting my computer for like half a hour because it just keeps happening. It sometimes freezes my computer completely, that my audio player's music suddenly slows down and I need to hard-restart. It also causes green pixels to flicker on several dark gray surfaces and purple pixels to blink on a lighter gray surface, such as the shadow on the right of this page's body, there's a nice stripey horizontal line of those appearing. They usually start appearing after the graphics crashes, not right from the booting.
So that's the problem that I get and cannot find any solution to. I've tried completely reinstalling my NVIDIA drivers through safe boot, even the older ones or the newest beta ones, and since the last fall or so, no driver wiped the problem for me, so it's probably not the source of it. From the recent observations through MSI Afterburner I've spotted that the pixels start flickering once the Core clock goes to 135 MHz. That explains why it never appears it games, because it goes up to like 1200 MHz usually. I haven't checked if it's clock is still 135 MHz even before it crashes for the first time and causes the pixels to appear and stay like that all day.
So what I found that could be a useful solution was to wipe the dust out of my graphics. No, that's certainly not the problem, as it's not overheating at all and it was happening right as I bought it. Another solution was to fiddle with the DVI cable, no help since I've already switched my monitor to ASUS VE247H and even have a dual screen now, both connected to the GPU, as I was told it raises the idle clock- nope it doesn't for me, or at least not enough. And what I think could finally solve my problem is to raise the default 2D / idle clock frequency, as I can clearly observe that the clock, right after overclocking, won't cause the pixels to flicker until it gets to the 135 MHz.
So my question is, how can I raise idle clock on a NVIDIA graphics card? The MSI Afterburner's 2D profile selector doesn't work for me. It might does, but it certainly doesn't affect the minimum clock. And all the other answers that I found were pointing to some profile changer on CCC which I also don't have since I'm not on ATi. So is there any other, reliable solution to that? I even planned to change my detault OS into Linux because of this, but that would make me unable to play many Windows-only games.
