So, I'll try to be as succinct as possible.
PSU: Corsair CX 600, which I have since 2011.
GPU: GTX 660 Ti SC, I have since nov. / dec. 2012.
Since last year, in some rare occasions, the video signal of my GPU did not reached the monitor. Sometimes I took it to clean, in others I just rebooted and waited, and that's it, the signal came back.
But then, the biggest problem has happened recently. I was running The Elder Scrolls Online in full spec as I had done for 20 hours. However, as soon as the game started, the PC started to freeze with a "robotic sound", drastically reducing the FPS until it crashed. When I rebooted, the video signal was gone.
I took the GPU off, cleaned it, rebooted it several times and the signal came back. It works fine with normal using, but when I try to run a game, the PC crashes soon after it starts.
I did a stress test in the processor, it's ok. I did in the HDD, in RAM, I believe it's ok with them too. But when I did with the GPU with 2 softwares (FurMark and Unigine's Valley), it crashed like in the games, right after the start of the test. It is important to say that the temperature does not even have to be high for the crashing.
I tested the onboard video and it's OK. I tested with an old GPU, a GTX 550 Ti (it has no HDMI input, I used DVI-VGA adapter) and it's also OK. Oh, I did a stress test with the 550 Ti too, and it was OK, no crashing (though it needs much less power than the 660 Ti).
With this same GTX 550 Ti, I was able to play Dark Souls 2: Scholar of the First Sin in 1080p with everything maxed out, 60 fps. I also played The Elder Scrolls Online with high specs, around 35 fps. No crashes. But emphasizing once again that it requires much less power than the 660 Ti.
What do you think? The video card (GTX 660 Ti SC) works in normal use of Windows, crashes when it is required for games. And there are these sporadic signal drops when Windows starts. But I had no problem with the 550 Ti so far.
