My computer works and passes through the bios when I installed my new power supply with integrated graphics. When I install it with the physical graphics card (gtx 750) it stays on the start menu and wont pass through the bios. My computer parts are compatible, my power supply is 500 watt and gtx 750 needs atleast 450 watts. I don't know what the problem is and I need some help.
