Graphics are glitching out

[tddk25]

So for a little while I have been having issues with my PC, hoping they would be fixed by a GPU driver update, but they haven't disappeared. Sometimes while I'm using an app or something my PC will start showing artifacts all over the screen, or it will go black for half a second and then come back on with buttons gone, forcing me to have to hover over everything to see it all again. Every once in a while when my PC attempts to fall asleep after idling for a few minutes it spits out a "No VGA detected" beep code and then the display wont wake even though fans are still spinning and whatnot, forcing me to force reboot in order to use it again. I don't know what to do now.

 

Here's my specs:

CPU - AMD Ryzen 5 5500

Mobo - ASRock B450M Steel Legend

RAM - OLOy DDR4 2x8GB 3000MHz

GPU - Sapphire PULSE Radeon RX 6600

SSD - HP S700 1TB SATA

PSU - EVGA 650 N1

OS - Windows 11 Pro 23H2

Monitor - LG Ultragear 24GN60R-B

 

All drivers & software are up to date, all cables have been checked and work perfectly fine.

Any and all help is appreciated
