Faulty Graphics Card, or something else??

Hi guys,

A year and a half ago I bought my first major gaming PC. It has been great up to this point, but all of a sudden, a few days ago, after downloading Witcher 3 and opening it for the second time, something just... crashed. I could hear the sounds of the game still, but both of my monitors went black with a "no signal" error and a Windows disconnecting noise, and I had to shut off the computer.

When I started it back up, only one monitor would connect (one was plugged into my graphics card, the other into the integrated ports... long story, don't ask...). Anyway, with the one monitor connected to the integrated ports using my basic af intel graphics, I was able to look around and to my surprise my gfx card wasn't even connected anymore-- it's a GTX 970, and my device manager was acting like it wasn't plugged in anymore, as well as GeForce experience being unable to open/telling me there was no Nvidia card on my computer.

Eventually I tried taking out the card entirely and then putting it back in, and finally got it working properly. Everything seemed great, I was able to plug both monitors into the card and boom, back to normal. I decided to give it a whirl by opening up Assassin's Creed: Origins and was able to play without issues on High settings for several hours... before, once again, to my dismay, the same issue happened again, except this time seemingly worse.

I got the Windows noise again, the game sound stopped altogether, the screens went black again, and no amount of restarting got them to reconnect (presumably due to being plugged into this newly-problematic gfx card). At this point it was 5am and I really didn't have the time or brainpower to go digging around again so I just unplugged everything (the cords connecting my monitors to my gpu felt sliiiightly warm, not crazy but definitely a bit warm, and only those cords, nothing else) and left it to sit overnight, out of a mixture of frustration and fatigue.

My question is, wtf is wrong, and why so suddenly after a year and a half of service without issue? Those games aren't even the most graphically intensive ones I've played, it's run plenty of heavy titles before and didn't complain. Is my GPU just failing me? Do I need to go buy a new one? PLEASE please help me, I'm at a total loss here and I'm so frustrated.

Something to note: ever since getting the PC, when I play games, I have gotten this high-pitched audio whining noise (from speakers/headphones, not pc itself) and the monitor not hosting the game gets faint horizontal flickering lines. I was never able to fix it and it wasn't a huge detriment so I let it be. But could this be an indicator too that my card has been faulty all along and it was just a matter of time before this happened?

**EDIT:** PLEASE NOTE I am not the most computer literate person, enough to stumble my way through most things but I had a friend helping me up to this point with all of this, but now we're both fairly stumped (other than just assuming it's dead, Jim). Please talk to me like I'm an idiot and explain any troubleshooting procedures if you offer them!
 
Solution
it does sound like the GPU. another thing i though would be the power supply but since you are saying you can still hear the game when the monitor goes black rules that out in my view
I think that what you describe could be indications the card is failing....especially the fact that the card wasn't recognized. I'd inspect the card visually and see if it smells burnt....if I didn't find anything, I might try another card just to see what happens.
 


That's my fear, yeah... and of course Nvidia doesn't want to replace it because it came with a prebuilt computer (Lenovo). They sent me to Lenovo but they won't touch it either due to the warranty being 5 months expired. So if this is the case and my card is broken, it looks like I've gotta shovel out a good chunk of money... 🙁
