RTX 2070 not recognized - no GPU shown

[Jan]

Did you do anything specifically apart from the restart?

@HaloJones: Wouldnt recommend the try if I hadnt made certain experiences myself...

No, did nothing special, just created the log and saw that GPU had appeared in the system description...

But now I have another issue: when using the GPU to fold the whole PC crashes from time to time....

...when using the GPU to fold the whole PC crashes from time to time....

That might be cause by any of these issues:
1) Corrupted installation of drivers
2) Faulty hardware of the GPU
3) High temperature of the GPU
4) Unstable PSU
5) Unstable Overclock of the CPU/GPU

Download and install MSI Afterburner. You can try reducing the power limit to 90%, and/or increase the fan speed from Auto to 90%, downclock by reducing the core speed.

When it crashes what exactly happens? Blue Screen of Death? FAH fails? The desktop locks?

Will try MSI Afterburner - crash results in black screen and restart of PC; no blue screen or anything

sounds like a hardware fault then. software faults will usually give either a BSOD or a reset to desktop.

I would be looking at things like temperatures (give the system a good clean, get all the dust out with a can of compressed air and a vacuum) or the PSU (a 2700X and a 2070 will draw a chunk of power).
