So yesterday i built my new game pc, specs:
Ryzen 5 2600x
Rtx 2060 Super
16gb ram
240gb ssd
1tb hdd
650 watt psu
Asrock b450m pro 4

everything works i installed windows 10. Then i Saw my gpu didn’t show up at task manager and at device manager it said Pcei with an unknown symbol, in my bios the gpu didn’t show up either
So how can i fix my gpu so it will show up and work
