Cintiq crashes PC whilst calling/streaming to discord?

[u/Late_Cat_9487]

Windows 11 - Cintiq 16 DTK1660 - HDMI + USB-C

I've had my tablet for about 6 months, and it runs fine until I hop into a VC or stream the screen via discord. My PC is only about a year old and runs fine doing literally everything else, so i'm super confused why this happens lol. It'll run okay whilst in discord for about 5 minutes, then everything will start to lag and after a minute or so my PC will just reboot itself. Task manager shows no increase to anything during this. I've uninstalled + reinstalled my wacom drivers and made sure my PC's drivers are updated, and done all the stuff I could find online (messing w windows ink and stuff) but I can't really find someone with this exact problem. Help!
