Recently replace a GPU in my computer and the computer seems to restart after awhile in windows. I don't know why, it just seems to happen randomly. Regardless of being in idle or underload. The card it had was a gtx580 the card that is now in there is a gtx780. I used a corsair 750PSU, both GPU needed a 6 pin and 8 pin connector. I tried removing drivers and such and downloading them again just to see if there was any conflict. Temp for each wasn't going above 90 degrees either. I used the GPU in a seperate computer as well and it seem to work perfectly fine. I am at a lost at what to do.

Hello... use the small app GPU-Z will give your fan speed and other important data... https://www.techpowerup.com/downloads/2627/techpowerup-gpu-z-v0-8-7

7) Since it's New... won't be a worn out fan, dried out thermal paste, or OC/MOD flash problem?
8) running LOW 80's is best for the GPU's... have you tried the a OLDER or original driver for the Card?
9) Try cleaning the Video card connector with rubbing alcohol and re-inserting the card a couple times for good electrical contact.
10) LOOk here to see if the reason for the crashes is really from the GPU hardware and/or driver...

Hello... 1) As a "simple temperature test" remove the cover from your case, to increase cooling air available to your Components.
2) What is the idle temp of the GPU... in your OS Desktop?
3) What is your idle fan speed of the GPU... in your OS Desktop?
4) Did you buy the GPU Used/New/re-conditioned?
 
Try running the rig with the case side-panel removed (open). See if this helps. The cards might have a different cooling solution: one might have a blower fan which exhausts hot air outside of the case, while the other might have a regular one which keeps the heat inside. Removing the side panel will make this irrelevant so we will know better what to do next.

I'll give it a try, but right now I can tell you the temperature for the CPU is 42 degrees, Motherboard 34 degrees GPU 41 degrees harddrives 27 degrees (All in C) I have a HAF 932 coolmaster case as well so I feel I am gettin gthe proper airflow in and out.

5) What are GPU and Mem clock settings programmed/flashed?
6) what make/model/prt # is the GTX780?

The GPU were both new, had them for a few years, I only replace the gtx580 with a 780 because my other system got a new GPU. Both running on windows 10 64 bit. The current idle temp is 36 degrees I don't know how to tell the idle fan speed of the GPU.
