Having just built a new PC, I have a problem where I plug in the monitor into the HDMI port and power it on... and I see the motherboard show the first thing you would typically see as the computer would normally start up (some info about the motherboard, brand, whatever), then instead of going into the normal login screen where I can login to Windows, the screen goes dark again as if the computer had been turned off.
Making things even more weird is that the whole PC was working fine the last two days. I logged in, got into Windows, downloaded a bunch of my favorite browsers, games ,etc... and played a while.
Some backstory: right after building the PC, I had a problem with no display showing up on the screen. I did something with the cable running to the monitor, and that fixed the problem then -- for that day. Then I came back the next day and had a problem again with no display image showing. I had wondered if it was a problem with the particular cable I was using (display port to HDMI cable made by Amazon) which I had got brand new, so I got an HDMI cable from a family members' PC after that, plugged it into the HDMI port, and it worked -- for a day.
So I thought Amazon simply sent me a bad cable. But now today I'm finding that the HDMI cable that worked yesterday is no longer working. Now I'm getting the motherboard info to show up on the monitor for a split second, then the screen goes dark.
I have no idea what the problem is at this point. I had wondered if the case was interfering with the cable going into the HDMI ports, so I used a file to shave off some of the plastic on the cable near the port to make sure it could go into the HDMI port all the way. It doesn't seem to have helped at all. The cable went in as far as it could go (which was not far enough in to touch the GPU's metal btw), and the problem persists.
I have no idea what to do at this point. It feels like pure dumb luck at this point if the screen makes it to the login screen or goes dark.
