GPU PSU combination reboots pc

[victoroos]

Hi all
My hardware to start with
MSI Z97 GAMING 5 - Socket 1150 - ATX
I4790 K
Crucial 8GB DDR3 PC3-12800
Gigabyte 1070 gaming 8gb
Cooler Master G750M

This si my first post ever, but yeah, let's see

I recently bought a 1070 as an upgrade from my good old 760 MSI. It did it's job, but I wanted to play games better, render beter, and especially run P3D (a flight sim) better . And wow it worked.

However. I had a random reboot, I noticed my cpu was getting hot, also with the old gpu, so invested in a cooler, and that was fixed.

Still it sometimes rebooted, mostly/only (it is too random to tell) when running p3d.

I swapped the 1070 with my old GPU, and for now, it works fine.
Can my GPU be that faulty that it works with normal usage, but crashes when running certain software?

When did you last load a device driver ? New drivers fix problems (or sometimes introduce them). Try different driver versions. Driver comes from www. nvidia.com.

Is it only certain games that crash? Check the game for patches. check the games forum.

UNDERCLOCK your video card about 10%. If all the crashes go away likely its a marginal video card.

Drivers have been tested, to no avail unfortunately.
Game has no patches 🙁
I will try that, what is best way of going into it?

I just did a lot of tests with my old 760, and no problems at all.
Could ir be my psu? EVen though it powers the 760 fine.?

edit: re PSU, anything is possible, but your 760 TDP was 170 watts, the 1070 uses only 150 watts.

Ehm, how would I underclock my card.
Also,w hen running different software, ti works fine.

Overclocking software like MSI afterburner, EVGA precision and Gigabyte EasyTune allows you to change the clocks on your video card. They are free and work on all makes of cards.

Usually people use these tools to bump up card frequency. You can use the same tool to drop frequency down about 25%. Do both GPU clocks and memory clocks.

If the problems go away then slowly increase back towards stock clocks. If you get 98% of the way there you might choose to keep the card. If the card is stable at 85% of clocks, but fails at stock then RMA the video card.

Good Luck.
