A couple weeks ago my monitor started going black and after a second or two, it would come back on as if it had just lost connectivity or if it had lost power (It displays "DVI" in the top left corner when it comes back).
My first thought was that the monitor was going bad (it was a couple years old and an off brand). So we bought a new monitor. Hooked up the new monitor...same thing.
So next thought is maybe the video card is going bad, so we switch from DVI to HDMI. Same thing.
Next, I thought the video card might be going completely bad and the computer is about 5 years old so we buy a new computer. Same thing.
Tried a battery back up, same thing.
The monitor never loses power, just the screen goes black.
So to recap we have tried:
1. New monitor
2. Different connection
3. Different computer
4. Battery backup
5. Plugging it directly into the wall
6. All drivers are installed and up to date.
The only thing that hasn't changed is an Intel Solid State Drive...I am out of ideas!
Hmm. I think it is the cable/connection. I had the issue before and I unplugged and replugged my cable a few times into my screen AND graphics card and the problem was solved. Try using a VGA cable and see if that works.
I actually have the same problem. Tried changing out cables, from VGA to HDMI and back again. Tried installing a new known good video card. Installed up-to-date drivers. Nothing still have the same issue. It almost seems like the signal is lost for a moment, and then just comes back. No clue how to fix at the moment. Any ideas?
(the system in question also does not have a virus)
