Since this mobo has onboard graphics also, use that to check in Device Manager if the card is recognised and has the right drivers.
My brother just upgraded his pc's graphics card from a gtx 1050 2gb to a gtx 1660 oc super, he installed it and now the pc turns on but there is no display, his power supply is 650w, his motherboard is a MSI B350M PRO-VDH.
What could be the problem? he has everything plugged in and the fans on the gpu spin but nothing shows up on the screen. The graphics card is brand new ordered from a local tech store.
Any help is welcome
