GTX 780 crashing

[mastarnaab]

Hi. My gpu has been crashing lately. Few times it displays the "Display driver stopped responding and has recovered" Windows notification, but once it blue screened and before that, the screen just went black and I had to restart the computer. Few times it has also booted itself when Windows froze.
I tried updating the driver after the first time it crashed, didn't help. Neither did updating back to an older driver. I also used DDU to do a clean install. Heat shouldn't be the problem, gpu is under 30 C without load and like 31 C on load (I tested on Pid, not the most demanding game, but full graphics and stuff).
Sometimes the gpu crashed while just browsing, but the weirdest thing I noticed was that it ran Simple Planes at 60 fps on high and didn't crash, but when I pressed Alt+Tab, it crashed. Pid ran fine for as long as I played it, but when I quit the game, the gpu crashed few minutes later.

Here's my setup:
Windows 7 Home Premium 64-bit
MB: Asus Maximus Ranger VII
CPU: i7-4790K
GPU: msi GTX 780 This one
Ram: 16GB Kingston HyperX Fury DDR3 1866 mHz (if I remember right)
2x Kingston HyperX Fury SSD (1x 128GB and 1x 256GB)
PSU: Corsair 600M I think it's this one

I still have warranty left on my gpu, so should I return it? Or is this an easy fix? Thanks in advance!

but once it blue screened

faulty RAM can also caused BSOD. run memtest86 just in case to see if your RAM is faulty or not.

Few times it has also booted itself when Windows froze.

sounds like power supply related issue. even if the PSU not faulty total system freeze would point to power supply cannot provide enough power to the system. what kind of restart did you have? did it crash and reboot your system or simply restart your system out of nowhere?

PSU: Corsair 600M I think it's this one

600w should be enough for 780....if the said unit is a reliable one. but those corsair CX series is more for their budget build. quality wise they were not that good.

RAM wasn't faulty.

what kind of restart did you have? did it crash and reboot your system or simply restart your system out of nowhere?

Windows froze for a few seconds and then restarted.

I think I may have solved the problem, because earlier I opened my PC again to triple check everything and I had forgotten to check the GPU power cords. They weren't loose or anything, but I pushed them in just in case they were. Afterwards I booted up and I haven't got any problems after. So, umm... maybe the cords were loose the tiniest bit for some reason and couldn't provide power consistently for that reason? Haven't touched those since I built my PC 2 years ago, so don't know how they could be loose. But thanks for the answer anyways, hopefully it may help someone else/me if I spoke too soon.

Well, I spoke too soon (damn it). My computer went to sleep mode and when I turned it on again the screen was all black, but otherwise the computer seemed to be working. So the PSU could be the problem?
Edit: I haven't got the driver has stopped working message and system seems to be working fine, so the gtx hasn't crashed now I guess, so it just ain't getting (enough) power?

probably power issue. GTX780 is quite power hungry. and Corsair CX series is not that good either. if you got better quality 600w unit it might not be a problem.

Cheers, I'll look for a new better psu then. Thanks for the help!

Try underclocking it by 50-100mhz.

I doubt its the PSU to be honest.
