Poe constantly causing "input not supported errors"

Ever since two weeks ago PoE started causing "input not supported" errors. The cause is unknown but from searching around the result is either incorrect syncing or resolution issues. My guess it being the former rather than the latter since it happens haphazardly, regardless of playing in windowed, windowed-fullscreen or fullscreen mode and it doesn't allow me to alt-tab back to windows. A hard-reset is the only fix to get back to my PC.

The only way to start playing the game again is to use Driver Uninstaller and fully un-install all videodrivers in safe-mode before reinstalling them. This only provides relief for a day at most however, after which the cycle repeats. Other times I've only been able to play 20 minutes before crashing again.


At a loss, I fully formatted my entire PC and did a clean install of everything and all seemed fine. But now, 2 days later the glitch has returned. It seems to be something caused by PoE messing up the DirectX files, as I have no issues playing any games on the same resolution prior to a crash, but those games WILL crash afterward.

Hardware:
- I7-2600k
- 12gb of ram on 2 sticks, sometimes one of them is faulty and gives me a bluescreen when I use close to the limit. Crashes happen before this is even remotely reached.
- GTX960 fully updated, recent purchase
- 22inch - Iiyama monitor PROLITE E2282HS; native resolution 1920x1080 with separate sync of 56-75hz connected through HDMI cable.
- 750w power unit, also recently bought.
- Game is installed on an SSD.


I've tried:
- Running the game in all three modes: Windowed, Windowed-fullscreen and fullscreen.
- Running in different native 16:9 resolutions lower than 1920x1080
- Running with vsync enabled and disabled
- Running in dx9/dx11
- Swapping HDMI cables
- Switching input modes (HDMI/DVI)
- Running in VGA/Low-res mode
- Turned off windows driver updating
- Turned off power adjust modes for both vid-card & monitor
- Reinstalling the game
- Reinstalling video drivers
- Reinstalling windows

In short:
The "input not supported error" happens at random times whilst playing the game. A hard reboot is required to get back into windows. The error thereafter only happens when 3d-models are adressed, such as in the characterscreen. The log-in screen is accessible, it crashes when I hit connect. Other games crash with the same error after this happens in PoE, they are fine before.

If anyone has any resolution, or perhaps GGG sees this and knows that it is a programming issue in how the game addresses DirectX
