Hello, I am begrudgingly writing this post as I have not been able to search for a useful answer to my problems over the last couple days
About three days ago, I was playing Flight Simulator Steam Edition and my monitor suddenly switched to a black screen stating " No DVI Signal". I fiddled with the DVI Cable, unplugged it, tried the other port on the video card, tried the integrated video port, nothing. All the while the computer was just humming along, all lights and fans operating normally. I pressed the reset button and the computer reset but there was still no video signal. So I hard rebooted and everything worked normally. I went to bed after this and left it running.
The next evening, I tried to play Flight Simulator some more. Everything was fine for a short while. maybe 30 minute to an hour and then it did it again. Sudden " No DVI Signal" while the computer continues to run as though everything was normal. I rebooted and played some more until it happened a second time. I think I went through this cycle one or two more times before I was very suspicious of the video card and possible over heating.
A ran GPU-Z overtop of the Flight Simulator in windowed mode and my temps were never over 44 C. GPU load was never over 35-40% This had me rethinking my assessment of the GPU being bad.
After reading a few posts on different forums, I decided to clean the dust off of the Graphics card and the computer in general. there was some but It did not seem like burdensome amount.
After this I tried to use OCCT but I was not sure what I was doing so the test that I tried to run on the GPU did not stress it at all. After about 5-10 minutes, the temps were near 37 C and the GPU load was about 30%. When I finished the test, the DVI signal was lost again. It waited until after the test was over to conk out. After a reboot, I horsed around on Flight Sim for about 30 minutes and it worked fine.
So now I am here. not really sure what is wrong or how to go about determining it.

I'm at work so I apologize for not having all my specs memorized. I just wanted to get the ball rolling on this seeing as I'm being tormented by not being able to figure this out on my own.
