GPU usage jumps to 100% and PC becomes unusable

I have been experiencing an issue with my RTX 3070 founders edition where GPU usage jumps to 100% and any application I am using becomes unusable though the PC is not completely frozen(at first, it does get progressively worse). If I attempt to restart the graphics driver using keyboard shortcuts then I hear the beep but the driver does not restart, sometimes even the beep is not heard. If the beep is heard then I am generally able to launch task manager to turn off all applications I have running and then the driver restarts and the issue is fixed, although this is not always possible. I have the latest driver installed and hardware acceleration is turned off wherever possible.

edit: It has just happened again and I was able to turn off just discord which allowed the driver to restart, so I believe this may be an issue with discord.

The OS is windows 10 Pro and the rest of my hardware is as follows: CPU: Ryzen 5 5600x RAM: 16 GB Crucial Ballistix 3200 MHz CL16 Motherboard: MSI MAG B550 M.2 SSD: WD_BLUE SN550 1TB HDD: Seagate BarraCuda 2TB PSU: Corsair RM750x

I have my GPU in the top PCI-E slot and I have two monitors connected, both through displayport. One monitor is a 1080p 144hz(though currently running at 60hz but the problem occurs when running at 144hz also) and a 1440p 165hz.

Has anyone else experienced a similar issue and if so have you managed to fix it?

EDIT: Reinstalling Discord seems to have fixed the issue, but I'm not sure yet.
