Monitor turns off - GPU fan hits 100%

Hey guys.

I'm not sure if gaming is causing the issue but it seems to be. Whenever I play games I have problems.
Sometimes my computer's monitor will display the message "no signal" and my GPU will go up to 100% RPM, even when it was only running at 40% RPM before the monitor cut out.
If I turn my computer back on everything will work correctly unless I turn on a game and play for a while.

There's a second behavior that my computer may exhibit if I game: the screen will cut off but my GPU fan won't speed up - and when I turn my computer back on the CPU fan will not spin.
The motherboard is still supplying power to everything but the CPU fan refuses to turn on and the computer will not boot. If this happens I usually have to re-seat the RAM to turn the computer back on and have it work correctly.

My GPU and CPU temperatures seem to be reasonable. My CPU will, at most, reach about 50 degrees Celcius while my GPU will reach about 70 degrees Celcius.

I ran memtest86+ for about 3 hours and no errors came up; RAM doesn't seem to be the issue.

Any help would be appreciated!

CPU: i5-2500k
GPU: 560 Ti 448 Core - EVGA FTW Overclock

Im pretty sure its your graphic card drivers, or the settings. check if you have set it to automatic or manual. usually that's the problem. or overheat on cpu, motherboard or graphics card.

Thanks for all the suggestions everyone.

I looked at the nVidia control panel and though I was not able to find the "automatic" or "manual" selection I believe it's on automatic; I see the fan speed change in EVGA Precision.

I looked up my GPU bios number (70.10.61.00.62 (P1263-0010)) and it appears to be the latest update.

I don't think heat is the problem.

I need more suggestions! :pt1cable:

Thanks again.
 
on another forum a guy has an evga 570 and he claims he is getting the same symptoms as you.. it turned out that his gpu wasn't getting enough voltage when swapping between 2d and 3d then vice-versa he would get a voltage drop when the switch over happened and would cause the screen to go off. if this is the case for you, you will have to get in touch with evga and get an rma number if they cant supply you with a fix (give you the correct base voltage to stop this).
 
From the symptoms that you describe I'd say your problem is between your PSU and GPU. Hexit raised a valid suggestion, contact EVGA and see if they can help you out.

Also, depending on which PSU you got, I'd recommend to try a known good PSU instead of yours.

as suggested earlier , try using evga precision for monitoring fan vs temp graph according to your convenience..
And pls give the details of your PSU. Maybe it's the culprit.
If your gpu wont get enough amperes on the several voltage rails, then this is bound to happen....
