Hello, so I've got a somewhat odd situation. I was playing overwatch on my PC and it randomly turned off. When I tried to turn it back on, the PC powered on for 20 seconds and then turned back off and this cycle kept on repeating. (There was no display and no power received by peripherals when the PC was on). When I removed my GPU and connected the HDMI to the motherboard, the problem persisted. I removed my ram and replugged it in after which the whole system (without the GPU) worked fine. I reinstalled my gpu and started the system and it took a little longer to boot but it eventually ended up outputting video. However, now it outputs a few seconds of video and goes black for a few seconds. This cycle repeats itself. I am able to use the PC normally (haven't tried gaming yet) but this problem is still persisting. I tried updating to the latest gpu driver and now the screen has gone completely black. Please help as this has not happened with me for the two years I've had this PC. Any help would be highly appreciated.
My specs: i7 6700k, 2x8GB Ddr4 2133, MSI Aero GTX 1070 8g oc, ga z170 hd3p motherboard
PS: I'm fairly certain it's not the display (MG278Q) as its working fine with the PS4 and the PC when it doesn't have the GPU in it
 
Everything points to GPU failure. I'm assuming you have been using same video cable with motherboard and GPU to rule out bad cable here. Check some older version of GPU drivers first. If no change, try the card at another x16 slot to rule out motherboard slot failure. If that changes nothing, try the GPU at another machine to confirm it's the culprit.

It stopped displaying after I updated the GPU drivers. When I restart, I get a fuzzy red overlay for a few seconds (when the bios screen and windows loading screen displays) and then the display goes black again. So I can't really operate the system, let alone run a stress test or revert to old drivers :/ . Also my PSU is Corsair rm850x
And yes I've been using the same HDMI for both my PC and PS4 over the past couple of years and never had any issue. Unfortunately my Mobo only has one x16 pcie slot so can't really check the GPU with another slot.
Sorry for the difficult circumstances but any suggestions on what I should do next?
 
First step is to get rid of NVidia drivers. Remove GPU, used motherboard to boot to Win, and uninstall NVidia drivers. Then shutdown, put GPU back and try again with different version of drivers. Yep, that's a lot of work but it's necessary.
