Crashes and artifacts on NVIDIA GeForce GTX 660 Ti

by Herocool11 / December 31, 2015 4:59 AM PST

Hi guys! I am having serious problems with my PC and I think it has to do with my graphics card.
My PC keeps crashing, with no warning. the sound that was playing at the moment of the crash keeps repeating itself. some times I just get a black screen and then a pop-up saying that my graphics card drivers have crashed and successfully recovered. I am underclocking my graphics card with ASUS GPU tweak. These are my settings just after a blackscreen: http://tinypic.com/r/20aumaa/9 (If you can't see the picture just refresh the page and it will work).
As you can see, the GPU usage spikes after the crash of the drivers. The underclocking worked temporary, but now the crashes ar getting more frequent. I have reinstalled my drivers and my widows 3 times and the problem was just delayed. The crashes occur when I enter almost any game and sometimes I get artifacts when it crashes. If i underclock my GPU more than I am doing now, I get random flickering purple/green screens followed by the pop-up about the recovered drivers.

These are my pc specs:

That i5 has onboard video

So pull the GPU for now and keep testing.

The 660 was no power saver. That is, you continue to find PCs with sub-par power supplies. I either find it's the PSU or GPU.

20A rails. Picture.

In reply to: Thanks!

OK, let's find out the 660 Watts. From http://www.tomshardware.com/reviews/geforce-gtx-660-ti-benchmark-review,3279-16.html

So 325 - 117 = 208 Watts. One rail is only 20A or 240 Watts. That's way over my choice of 50% of a PSU load. And you can't be sure which rail you are using so this PSU wasn't a good choice.

Now if that was a single 40A rail then I would not be calling it out.

Wow! Thanks!

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
