Hello. Sorry if i'm on the wrong section.
I'm having a issue with my gpu, last week the nvidia drivers started to crash, making my screen black and showing a message that the drivers crashed, and sometimes my computer would permanently lose signal, only coming back if i hit the power button. I decided to format my computer. After formatting and installing 334.89 the problems returned. I uninstalled 334.89 on safe mode and installed 320.18. My computer worked normally for a few hours, but after that the same problem returned. After that, all nvidia drivers, when installed to my computer, started to lose signal after windows logo shows up, or works for a few minutes and loses signal, making the computer unusable unless i'm on safe mode. I'm clueless and i would appreciate any help i could get on fixing that problem. Thanks!

Specs:
Windows 7 ultimate 64bit
Intel i5 3450
EVGA Geforce Gtx 560 Ti
Mobo P8H61-M le/br
2x 4gb kingston ddr3
Corsair CX600

The gtx 560 ti was released in 2011 so your card is 3 years old, the recommended upgrade from nvidia is about every 5 years. Since your card is 3 years old you aren't quite there yet. If you have the tools available try swapping out the power supply for another that has enough watts to run your card, then if that doesn't work try running your system without the video card and see if the problem persists. I remember helping someone on the forum a while ago and figuring out it was just the dust in their system that was causing these weird crashes and errors. Another post on a forum from another person I helped we figured out that it was their power supply causing all of their problems. I'm 99.9% sure it is your power supply though

1-Yeah, power supply seems to be the problem, but does it explain that my computer won't work only with drivers installed?
2-Temp 41ºIdle, GPU Clock 50Mhz, Mem clock 135Mhz
I downloaded the software, would this stress test be the benchmark option?
Thanks

Well with the drives think of it like a fast car, when the fast car is going down the road at the speed limit (without the drivers installed) it doesn't need to stress its self out because it isn't working all that hard. Now when you put the fast car on a speed track where there is no speed limit it can push its self to the max(drivers install) So without the drivers your card is pretty much just at idle, but when you install the drivers you are giving your video card the ability to go as fast as it wants for what ever reason so it draws more power. one time when I was watching just a 480p video I noticed my system at the start wanted to use like 400 watts for no apparent reason just for a second. after that it went back down to its idle wattage pretty much. but this can become even more problematic with bad power supplies they can be delivering the wrong amount of amps to your video card and making it freak out blue screening and crashing.

One thing that is good to know is being able to self diagnose your problem by reading stuff like http://everydaylife.globalpost.com/signs-symptoms-failing-computer-gpu-29747.html for video cards. http://smallbusiness.chron.com/symptoms-bad-power-supply-69724.html for power supplies. both of those will give you questions to ask yourself while looking into the problem for yourself, there is only so much that a forum can do for you, but having a better understanding of self diagnosing your issues can help pin point your problem for further advice even more.
