Pro tools 11 freezes in the middle of a session

[yorgo]

Hello I have a new problem with pro tools 11 freezing in the middle of a session everything just stops and I can't do anything else. I can't control alt delete, minimize, nothing... it just stops I have to reboot the machine by just turning it off and turning it on. I thought it might have been a waves plugin that was newly installed. I had since deleted all my Waves plugins and everything to do with a waves and although it was better for a little while it has returned... please let me know what you guys need to know so I can get the help I need as far as info...

I'm on Windows 7, i5, protools 11.3.0, 8gb ram
