I say semi-randomly, because it usually this happens if I’m streaming something, typically youtube videos, but occasionally audio if I’m running a lot of other qubes. It seems to stream video more smoothly if it’s not having to play the video at fullscreen, but nothing is certain.
It also seems to have an issue with running a full anti-virus scan within a Windows 10 HVM. Those scans typically take at least an hour and the whole system crashes without fail about half-way through that first hour.
I’m assuming this is a hardware issue or limitation, so I’m wondering if I need to upgrade some components. The whole rig was built in 2014, so it’s getting old by modern standards.
