Hello,
I've a problem that windows detects a second monitor named Generic non-pnp monitor.but the computer keeps detecting that I'm installing and removing it continuously and make that sound you hear when you plug and unplug a usb device and it also cause a little freeze to my pc and stuttering and in the last 2 days it makes my pc almost unusable.I've tried to install a fresh windows and to uninstall my GPU driver completely and installing the newest one and then go back to 19.9.2 driver, I also tied another display, cable and HDMI port of the GPU but nothing changed and hope you can help me.
my PC specifications:
CPU:AMD Ryzen 5 1600AF stock
MOTHERBOARD: ASROCK B450M-Steal legend
GPU 1: ASUS ROG Strix RX 480 8gb stock
RAM: XPG Gammix D10 8gb 3200 DDR4
PSU: seasonic s12ii 520w 80+ bronze
