Hello guys, I need help with a bit of troubleshooting for this little phenomenon called "DVI No SIGNAL". There is a bit of a backstory to it, here goes:
 
Around April, this year, I had some issues with my GTX 550 Ti, and I had asked around some tech forums that whether it was actually dead or was there some other problem. Most of the replies suggested to check the GPU in another machine. I couldn't at the time test it as my friends PSU didn't have the particular PCI express power cable as he was using a GPU(AMD 6670) that didn't require any extra power. Anyways, I concluded that my GPU is dead and continued to use the onboard graphics of my motherboard. 
 
I didn't face any kind of display issues until a week ago, just before Christmas. The motherboard would now turn on the display, but the display wouldn't show the motherboard logo its supposed to show when we my PC would post. I went to computer repair shop as I wanted to check many things at once, and after some testing we found that one my RAM sticks and the motherboard weren't working, as using the other working components only on a different motherboard would start the PC without any issues.
 
Then I brought back the new motherboard and set it up and it started working. This time around every other components were the same except the discarded RAM stick. This time, for curing my curiosity, I tried to connect my GPU, the one I thought had died, on this machine with the new motherboard. Alas! It worked. I was able to use the GPU to not only turn on the display, but also play games without any performance drops. Until today. SIGH. I got the "DVI No SIGNAL" error again this morning. And as I quickly switched to using the VGA port of my new motherboard, my PC booted up without any issues. I'm now planning to properly check my GPU on another machine. But before that-
 
-the question is, has my GPU finally ascended into heaven?
