RC hard crashing entire machine during calculation

Hi,
Since couple of months I have a problem with machine randomly crashing during aligning/calculation phase. I’ve recently sent my PC to “repair” so they can find a cause of this problem. But I thought I will ask here if it’s possible that RC can randomly crash entire machine? I don’t have that issue with rendering in Maya or Blender.
I’ve done many tests and RC is doing it randomly when stitching for example 200-500photos, entire machine is crashing, fans are going crazy and I have to switch PSU off to reset PC.
I’ve read suggestions here about PSU, but my PSU is pretty powerful for this config.
Service technician is trying to tell me that it is RC problem as all of my parts are working perfectly in benchmarks.

My specs are:
Asus ROG ZENITH EXTREME
ASUS ROG Thor 1200w PSU
Geforce AORUS RTX 2080 Ti XTREME WATRFORCE
AMD ThreadRipper 2990WX
Corsair 128GB ram

Cheers,

Jacek

Hi Jacek,

             I’m afraid it is still very likely to be a hardware problem as your entire machine is crashing and not just the application.  We can test one of your datasets if you contact us at support@capturingreality.com, but it is extremely unlikely that we will be able to reproduce the problem.
