Critical crashing, freezing, and failing. Won't export anything.

Hi all, I've come to you in a time of dire need. I've picked this forum because the problem has manifested itself most in Media Encoder, although I suspect it might be a larger scale issue.

I've been having issues exporting anything from media encoder, or premiere. Here's what I know: 

-It started with issues processing wipe & dissolve transitions between AE comps. Gave me error code -1609629695. 

-It's expanded to freezing about 10 seconds into exporting any video

-It seemed to come out of nowhere about 3 days ago

-I've exported the same projects in the past, but now can't 

-Often premiere crashes when selecting the problematic transitions

-The issue(s) does not go away when removing transitions

-Media Encoder sometimes fails render and gives error, and sometimes just freezes

-Sometimes my entire screen will go black, mouse goes unresponsive, and all software crashes after screen comes on again

-The video I've had most problems with is a premiere timeline with some animated AE compositions animating illustrator layers. Project has exported fine in the past. 

-When force quitting tasks in Task Manager, it often fails to force stop app until I restart. 

Here's the things that I've tried:

-Restarted computer

-Updated CC, intel drivers, windows, GPU driver

-Reinstalled GPU drivers

-Tried rolling back GPU drivers (Quadro Experience gives me an error)

-Reset preferences in AE & PR

-Reinstalled Adobe suite (Keeping no preferences)

-Cleared cache (Manually)

-Exported on a different machine (Seems to work)

-Toggling between CUDA, OpenCL, and Software encoding (no luck)

I'm starting to think it's a faulty GPU, but windows tells me it's running at good temps and utilization is still a 100%. Here's the specs:

Windows 10 64-bit

Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz 3.19 GHz

32GB ram

Quadro P1000

250GB ssd (Windows, Adobe CC)

1TB HDD

NAS external system (~21 usable TB, gigabit speeds, where project and footage is stored.)

External devices & excessories:

Wacom drawing tablet

Logitech speakers

Blue Mic

4k60hz monitor

Thank you anyone & everyone for helping me figure this out.
