Garry's Mod Screen/Graphics Problems

The cause of the issue is unknown to me but this has been a problem for a while.
Upon start up of a map on GMod, the screen (in a way) freezes and the help popups and the HUD glitch out, I then am unable to move or interact with the world around me and firing the weapons sometimes lets me move but once I move the camera (via mouse movement) the screen freezes again. I can hear the sounds of the game and I know the game is still running.

I have 2 pictures of information sadly I am new to the forums and I have no idea how to attach the file, one is of the console upon map/world start up and the other is the game upon map/world start up.

Any help would be appreciated.

Thank you for reading.

Fixed the problem by myself, mouse acceleration was effecting the screen somehow.
