Freezing Whilst on Multi-Player

The title pretty much states the obvious, my game sort of freezes while im on multi player. I can hear people use their mics, i can also see others move around while im frozen. does anyone know how to fix whats happening to my game? It has only been doing this for the past few day and i even deleted all gmod files and re-installed gmod and it didnt fix it. ill try and take a video of it happening. (It also happens on all servers i play on - and all gamemodes)

Make sure your graphics card drivers are updated and try removing any addons and workshop subscriptions you have
