Hello everyone!

Last 3 days i am trying to solve my problem which suddenly appeared after 2 years of Palit RTX 2080 Super Jetstream GPU ownership. While playing CS:GO or benchmark with 3dMark at different intervals a black screen appears and the fans of the video card spin to maximum, i still can hear audio and pc interface sounds, but only hard reset helps.

I tried many things as reinstalling drivers with DDU, replacing vga cables etc etc, nothing fixed my issue. Finally i tried my GPU on friend's pc with 1000W psu and faced the same problem.

What i already did:
  • Tried DDU uninstall and install different GPU drivers
  • Updated MB BIOS
  • Changing GPU clock offset to -200 Mhz, Power target to 70%
  • Maximum performance option in Nvidia control panel
  • Switching to the GPU BIOS without factory OC (there physical switch between 2 kins of BIOS on the GPU) - Replacing 2x8pin VGA cables PSU -> GPU

Right now i logged sensors while crashing in 3dMark benchmark with HWiNFO64 and here it is (The exact time of crash is between 23:38:20 and 23:38:30, 816-820 rows in csv document):

Also getting the warning in the event viewer: "Display driver nvlddmkm stopped responding and has successfully recovered"

I am grateful to everyone who could help in solving my problem

I just noticed that, judging by the logs, right before the crash, GPU D3D Usage [%] and GPU Video Decode 0 Usage [%] increased from 11.7 to 95.5 and from 2.5 to 100.0 respectively, and then dropped to 0 and did not rise until the computer was restarted. Also GPU Memory Usage [%] dropped from 28.0 to 3.9.
