Nvidia 2060 Super - GPU Has fallen off the bus

Hi,

Not sure if this is the right section, but here goes. I have been having infrequent intermittent hard crashes, apparently related and/or caused by GPU issues. In general, crashes tend to happen while playing World Of Warcraft and simultaneously watching netflix on a second monitor. Usually the screens will freeze while audio from the browser will continue for a few seconds until eventual total freeze. I am unable to change TTY during this time and a PC reset is required to restart.

Looking through journalctl today when I experienced 2 back to back crashes, the following was logged:

Feb 05 15:37:16 Minas-tirith kernel: NVRM: GPU at PCI:0000:26:00: GPU-2d809996-f440-6cd0-8042-b1f3c039047e

                                     NVRM: the NVIDIA kernel module is unloaded.

Looking around the forum, there seems to be several mentions of similar errors related to suspend/waking up from sleep, particularly in laptops; or issues related to low power supply output. I will be checking hardware, but my 600W psu should be able to handle the load on my pc according to:

Overtemperature or undercurrent is plausible - did you forget to attach the dedicated 6/8-pin power connector to the GPU?
Is it fittet into the PEG slot?
Otherwise the journal *before* the XID 79 might provide insight into the cause.
