Random Crashes/Lagspikes

[QuickLoad]

I started my computer today to find me unable to use my launcher, I restarted it and it was fine.

Then I went onto play, I joined an internet server and had massive lagspikes ranging from 8 seconds to 4-5 minutes. After around 20 minutes of joining a game i'd get a black screen and it'd say "Unloading Resources" and close my PR.

I restarted PR several times and kept joining internet servers, i still had lagspikes but I was crashing more frequently, even 2 minutes.

I tried a co-op server, as soon as I join, 15 seconds later it'd say there's a problem with my connection and boot me out of the server.

Any fixes? Thanks.

Try making a local co-op game and playing there.

My local co-op works perfectly fine.
