PC Blackscreening

[CrowCrow]

First time using the forums, but can't figure the issue out myself and thought others might be able to help me see what I might have missed. PC started to black screen after 15-45 minutes of gaming then will display "No signal". When not gaming PC is fine but has now started to black screen as well when just doing other task like watching streams etc. and shut my whole PC down then wouldn't boot for 15 minutes a few days ago. I've re-seated the GPU, tried to adjust the underclocking settings, swapped out PCI cables and have 2 PCI cables going to my GPU to the PSU. My temps never go over 65C when monitoring them and when I've done stress test PC acts fine. My GPU is a 3070 with a 850 watt PSU gold. Monitors are a 24 inch and 34 inch ultrawide monitor. Thanks for any help! Edit: OS is windows 10 and Bios is American Megatrends

You can try the following-

 

1) Blow your pc parts using an air blower to remove dust. 

 

2) Download 'Advanced System Care Free', run a scan and repair. 

 

2) Go to Windows Updates and click 'check for updates'. Install if any. 

 

3) If problem still not solved, DDU install a stable driver for your GPU from official Nvidia website.

 

To me it seems a PSU problem because it seems like the GPU is not able to take enough current under heavy loads during gaming. Try to test your GPU in some other pc if possible. 

 

Went through and tried the steps but problem still persisted. Think you are correct and it might be the PSU. I swapped out the 3070 with my old 1060 and it ran fine for a bit but after 30-45 minutes black screened again.

Tried to clear but the problem still persisted. Think it might be the PSU. I swapped out the 3070 with my old 1060 and it ran fine for a bit but after 30-45 minutes black screened again.

It probably is the power supply at this point
