Hi all! I've been building my first PC (thus first motherboard ever). My boyfriend and I put it together. We have everything connected, and the computer turns on. But the VGA light comes on every time. The monitor I have plugged in to the HDMI port stays black, no signal to it. We have tried reseating the graphics card, reseating the RAM, checking the GPU for damage (none), replugging the power supply, replacing the monitor HDMI cord (nothing wrong with it). I tried hitting the reset button a couple times, nothing. I hit the flash bios button, nothing. (I may have ruined everything) The graphics card's fans spin, the processor's does too, the case's fans come on. So where is the problem? Please help!!
