Hi, I got a 4k monitor and my GTX970 causes an instant hard-reboot if any 3D load is on the GPU in 4K. Non GPU intensive, non 3D apps never crash. However the same system running in 1080p will run fine video games and video benchmarks all day and night. It is not a temperature issue, I tried many video drivers, tried different cables, PSU, different GTX970. The reboot issue has something to do with the GTX970 GPU running in 4k and having any load put on it via a game or OCCT, even a 1% GPU load test. I suspect there is a setting or driver change that can fix this. I appreciate any help. Thank you.

Hello,
Graphics card works fine with 1080p monitor, and works fine on a 4k monitor running 1080p resolution. But running in 4k on a 4k monitor the card reboots machine on any GPU 3D load. I'd like to run native 4k resolution if possible and not have to drop the monitor resolution down to play a game if possible.
OS: Win 10 home, build 19041
Board: pegatron corporation, 2AD5, v1.03
BIOS: AMI 8.21
VGA: MSI Geforce GTX 970 4G
PSU: Corsair RM650 - (always less than 300w total peak usage)
CPU: Intel i7-3770 @3.4ghz 4 core
MEM: DDR3 2x4Gb
HDD/SSD: Samsung Evo 500gb
Please let me know if you need any more info.
Thank you.

Can you test the GPU in another PC?

I replaced the Corsair RM650 powersupply with a cheap Thermalake 700W and no more issues.

Super, the PSU was also suspected, but trough it would be more easy to test the card in another PC

I think bad PSUs account for the majority of video card-like problems. As the video card suddenly demands more power, if the PSU is damaged in any way, especially it's power monitor tech, it shuts-off power.
