So, a week ago, I tried to boot up my computer, but the graphics card gave no signal, just a blank screen. So I got a new one and tried with that. No signal. Now I check the computer's UEFI bios, and it says the slot I put the graphics card in was empty. I don't see any option to turn off the integrated graphics I was using. It is a MSI MPower Z87 board. What do I do? Should I get a new one? EDIT: I vaguely remember disabling something to do with the PCIe in the Device Manager the day before it broke down. But I can't seem to see it anymore. What do I do? Would reinstalling windows fix it?
