So I just finished building my pc and when I booted it up, installed windows and then after I restarted the pc, it gave me a bios warning saying that my cpu was overheating. And then I remember I forgot to peel the plastic guard. So I peeled it off, cleaned the old thermal paste and reapplied, and reinstalled my cooler. But all of a sudden, my pc turns on but my monitor detects no signal. It’s not my monitor because it turns on and it detects the displayport. So far I have tried different cables(including hdmi), different monitors, reseating the gpu and cpu, removing ever cable, as well as resetting the cmos. The pc is on, all the lights and fans are working so I don’t know what is wrong.
