so i built a pc for my brother and when i was finished the screen couldn't find a signal, i tried the hdmi port on both the motherboard and the graphics card, i tried the dvi port and the vga port (which was only avilable on the motherboard)
i tried different screens and hdmi cables, but it seems that the problem is not just with the screen signal, as i couldn't turn off the pc using the power switch or holding it, i also tried turning on the pc directly from the mother board and it didn't seem to make much of a different, i already installed the graphics card driver by using a different system and it didn't make any difference.
as for the specs they are: msi gtx 1650, ryzen 5 2400g, gigabyte a320m-s2h, and a coolermaster 650 w 80+ gold semi-modular powersupply.
