As the title says, my pc has started suddenly freezing when I’m gaming, I’ll load up and within a few minutes the screen completely freezes up and I have no control. Weirdly, audio remains, but m&b do nothing and the screen is frozen.

I’ve run CPU tests and they come back fine, running a RAM diagnostic as we speak, but is there anything else I should be checking?

Temps are looking fine, my 4090 was around 70 and cpu was even lower when the crash happened so I don’t think thermals are the issue, but I’m worried as hell that the GPU is just toast (still in warranty so not end of the world, but I don’t want to go down that road until I know that’s the issue)

Any ideas on how to pin down exactly what is causing the freeze? All drivers are up to date and as far as I can tell nothing even updated between last night and today so I have no idea why this is suddenly happening.
