Ever since replacing a GTX 570 with a GTX 660 Ti, my system has become unreliable. Is there anything I can do to determine if it's a hardware or software problem?
System reliability (after installing new GPU)
The evens in the Windows failures row are the Video Hardware errors. The ones in the Application events row are mostly Google Chrome and Mail (see below), and SimCity.
System reliability (before installing new GPU)
Hard to see on the graph, but this was a reliable system. I accidentally knocked out the power once, and the Application failures are mainly an MPC-HC bug that I know how to reproduce, but never submitted.
- Video hardware error. Happens almost daily, multiple times a day. If I see it happen, the screen might blink and I'll get a Taskbar bubble saying "Display driver has stopped responding and has recovered".
- Same error happens some time between sleeping and waking (apparent in Error Log). When this happens and Google Chrome is open, it will be a black window and not responding. When there are toast notifications from Mail waiting for me after logging in, they will also be black, and non-responding.
- Screen corruption in Google Chrome (this just happened after posting this question). Doesn't crash, but looks like this:
Things I've tried:
- Using a couple of different beta drivers, as well as the latest WHQL version. All have this same issue, except the beta ones cause artifacting in Valley Benchmark 1.0, and can't even finish the test.
- Switching the PCI-e connectors from rail 3 to rail 4.
The GTX 570 required more power, so I doubt it's a problem with my PSU. The PSU experts at JohnnyGuru have a lot of praise for my 750 W unit, but do say that there is some "12V ripple and noise close to ATX specs." However they also say that "while 12V3 and 12V4 are 1mV out of spec at 121mV. Now, we can ignore that 1mV number - your hardware won't care if it's that close to spec," but maybe this GPU is finicky.
