My media pc was what I is use for my vr headset was a custom pc from a Game Dev company and I upgraded the graphics card. I had stopped using this pc for about 6 months, now with all this extra time on my hands, I wanted to get back into vr. I booted up this pc and both the hard drive and ssd were fried, which was weird (pc us unplugged for 6 months). But I replaced the hard drive, and reinstalled the os log in and everything worked fine. I then changed the boot order of my devices and restarted my computer. The computer then would not output a display signal. I checked the cable and monitor, and they both work fine. I checked the Graphics card and it is fine. I also checked my ram as well. I then cleared the cmos, and tried to update the bios but the led light would not flash according to what the manuel told me. I then got a VGA LED light on my motherboard, I looked through my mobo manuel and found little about it. I know the graphics card works and that there is no onboard graphics. Could this be a problem with my PCI Port? I am out of ideas and any help would be great thanks.
