Hi, so recently I ordered in a new psu as I suspected my old psu was faulty. For a period the pc would crash instantly when playing games, and then after a bit the display just wouldn't power on at all. So I put in a new PSU and now it just simply loads up asrock BIOS each time I turn my PC on. It doesn't let me boot into bios through f2 to set to factory settings either. Any suggestions?
