Just installed a new GPU and psu to go with it. When I turn on the computer the screen stays black. Already put bios back to factory settings tried with a different GPU that does work. The fans on the new one do spin, only 1 of the 2 tho. I need help. Been troubleshooting for 7 hours now and im exploding.
