[PT 12.8.2] Crashing, Not responding, Ridiculously Slow

[Charley115]

Hi,

I'm having a bit of trouble with ProTools 12.8.2, constantly crashing, going into not responding and if it does decide to work being ridiculously slow. The one time where I did get it to work, I tried opening up the video playback engine and got a not enough CPU power error.
I've gone through the windows 10 troubleshooting and optimisation guide and done a new install of Pro Tools (Used Trasher to clean up any leftover files also). I've also tried the windows comparability mode which just freezes it on startup and needs task manager to close it.
If anyone could help shed some light on this that would be great as I've got university work that needs pro tools.

Specs:
Win 10 Pro
i7 7700k @4.8GHz (Stable)
16GB DDR4 @ 2133MHz
Running from a 500GB WD M.2 SSD
1080Ti GPU (Not that that should matter?)

All drivers are up to date including CPU, GPU, Avid and iLok.
