Computer crashing with few error messages

Hello All,

I am struggling to understand where things are going wrong. I have purchased a computer and have installed all/ most of the latest software to run cryoSPARC and have successfully read in the images, run the motion correction and CTF estimations on the movies and am trying to run blob picking. I’ve tried this several times with the same or slightly different parameters and each time it crashes the whole computer at a random point (a random movie/image). And when I say ‘crash’ I mean a hard crash- the only thing left going is the power light, everything else is dead.
I’ve got cryoSPARC 3.3.2, cuda release 11.7, NVIDIA driver 515.65.01.
The new machine has:
An AMD Ryzen 9 5900X cpu
Zotac GeForce RTX 3090 24 Gb gpu
64 Gb of RAM
Gigabyte X570S Aorus motherboard with liquid cooling.
One of the weird or interesting things from my viewpoint is that I’m barely using the cpu/gpu when the blob picking is going on, so it isn’t a question of the gpu or cpu running hot. We’ve done diagnostics on the hardware running the cpu/gpu at 100% overnight without issues (as I suspected that it was a hardware issue initially).
Any help would be very much appreciated!
Best regards, tom
