I'm going to try that next. I've just disabled the GPU sensors (by pressing Del) and I'm going to give it a go! Hopefully, we'll find the root of the problem soon!Thanks for your feedback.
The GPU was my suspect as well and you both guys have the Navi21 (RX 6800 XT). HWiNFO version 6.40 added enhanced support of these GPUs, so maybe it has something to do with that.
Would be interesting to see if the problem happens with the GPU sensor monitoring disabled in HWiNFO.
Thank you eveyone for your feedback.
