Lagging/tearing on desktop, now black screen or won't boot into desktop

Hard to describe in a title, I'll give a long and short answer. Short answer first:

My computer sometimes boots into windows normally, I sign in, windows is laggy, and there is some pretty bad screen tearing even when just dragging a window across the screen. Then always less than 30 seconds later the screen goes black and I can't do anything so I restart my computer. Sometimes it goes into it again, same exact thing happens, but then it can also go into a recovery screen, with a blue background. There's some options there, I've tried all that I think would apply to my situation. I formatted all the drives, and did a clean install of Windows 10 from a flash drive, got into windows, used it for a few minutes (still had laggy and tearing issue), then it went to a black screen, and I'm stuck with the same problem.

Longer explanation is basically that it's a custom built computer by me (some specs below), and it worked with no problems for two years. One day, I restarted my computer, and then when it booted back into windows, the screen was in a very low resolution and stretched out. I couldn't change the resolution in the settings either. Basically, it was running a lower (possibly 800x600px or something resolution on a 1080p monitor). I tried some stuff to fix it, even took it into a place and they didn't do anything. I got a new computer (works great, it's a laptop), but recently decided to try and get the old computer working again to hopefully sell, as it is no use to me anymore. I booted it up, still had the same problem as before, I updated windows, still had the problem, took out the graphics card, made sure it was all good, put it back in, still had the problem. I tried one more thing, and this is where it gets weird... I updated the graphics driver from the GeForce Experience software, let it automatically do its thing and restart, but this time it still had the problem but 30 seconds after signing into windows the screen went black and I couldn't do anything. I restarted my computer, and it went to the blue screen with the recovery options. This was so confusing, why would a driver update now not let me even get into windows? I clicked advanced options, reset, and tried resetting the computer (deleting all data and installing a clean copy of windows). It would always get to 35% then say there was an error. An error restting! Like what?!? Anyway, I used my other computer to creat a USB drive with Windows 10, put it into the old computer, formatted both drives (SSD and HDD. SSD for OS, HDD for storage/lesser used programs), installed a fresh copy of Windows 10. I booted it up, signed in as usual, still was low resolution, screen tearing/lag issue, and now after about 15 mins the screen went black and it's back to the same problem.

Basic specs:
GPU: GeForce GTX 780 Ti
CPU: AMD FX 8370
RAM: 16 GB G.Skill Ripjaws
MoBo: ASUS Sabertooth 990FX R2.0

Fresh copy of Windows tells me it's not a virus or OS problem. Screen tearing/lag tells me it's a graphics card, likely driver, issue. I can't get into Windows to update of course, there is a safe mode option but there is no internet and you can't plug in devices in that mode (I can get into windows in safe mode, btw).

Please help, I know this was a really long post, I really want to be able to sell the computer if I can get it working again, and if not at least have my friends use it or something. I don't want to buy a new GPU or anything.

Well, that's what gave me the black screen, and made me not able to get into windows at all in the first place. Like I said, I can't get into windows anymore, so I can't uninstall anything unless it's through the command prompt. The graphics card lights are on, and the fans are spinning, yes. I cleaned out the case of any possible dust, I have the case fans spinning as much as they can, I even had the card professionally cleaned to prevent overheating the other day (disassembled the card and cleaned every tiny piece of it).

Through the BIOS I can check the temps of everything, and they seem to be the same temp as it's always been when it worked.
