RX 5700XT causing PC lag

[o.Squidzz.o]

I have had my 5700xt for about a week now and ever since I installed it, after about 30 minutes of watching videos or playing a game, the framerate immediately drops to 10-15fps and my entire computer starts lagging and GPU usage spikes to a constant 100%. Once I close the program, my computer continues to lag, dragging windows around or moving my mouse stutters an insane amount, and causes desktop window manager (dwm.exe) to completely consume all of my GPU, anywhere from 30-100% when simply dragging a window across the screen. I have tried reinstalling windows, uninstalling drivers with DDU and rolling back to multiple versions all the back way to 19.9.2, updating all drivers with drivereasy, running intelligent standby list cleaner, setting dwm.exe priority to low, testing all priorities available for the games Im playing, changing ram frequencies, underclocking GPU, turning up fan speeds, reseated the GPU multiple times, I'm at my wits end at this point. My Rx 580 still works perfectly fine with zero issues. So I'm not sure if it's a hardware issue or if AMD drivers are just dogshit. Is this an issue with the card to where I have to get a replacement or is there something I can do to fix this? Thank you for any assistance.

Try DDU and reinstall your drivers

 

edit: sorry I didn’t read.
 

another edit: it may be a psu issue, I think rosewill power supplies may be less reliable, if you have another psu on hand try switching it out
