Gmod stops responding

Hi i just re-downloaded gmod after not playing it for a few months and when downloading files from servers it just stops responding i can go afk for 20is minutes and its working when i get back it really inconvenient AND when i get in the server i get 1-4 second freezes every few minutes, my computer is for gaming and runs most high end graphics games with 100+ FPS i just want to know if theres a way i can fix this or if its happening to anyone else or just me? ty

ps: since i last played i have gone from XP to windows 7 that’s about it

Use less addons?

Right now im only using phx and wire since i just reinstalled
