So I left my pc on at night for no reason, woke up and opened chrome then pc just crashed for some reason, thought it was a ram problem. The screen went black and it restarted itself automatically and i noticed it was back to like 800x600. I right clicked on the desktop and saw that there was no "nvidia control panel" i thought the graphics driver got removed for some reason so i installed it again and pc crashed again. Tried to connect the hdmi cable to my motherboard but then it didn't show the display for some reason and then when i plugged it back to my gpu it displayed. The weird thing is i can't install drivers and i can only use my gpu to show what's on my screen? I'm so confused. That's not all, my pc is SUPER slow now, for some reason gpu usage is at 30% constantly due to "desktop window manager" and my cpu usage is just way too much. Used to be able to use zoom and record with obs at like 10-30% cpu usage at best, now it maxes the whole cpu out, like 100%. So my GPU isn't working but it's the only way i can show my display and my whole pc magically got super slow, any tips as to what i can do?
