Is this a network or software issue?

Recently after installing my new graphics card my system periodically freezes. I would say once every 20 minutes. When im not playing games and just using my computer the freeze lasts about 30 seconds.
Problems:
I was watching a youtube video and the loading of the video stopped. The sound for my Discord cut off and every action i did (including minimize, opening a new folder, etc) was frozen or in some cases, took 30 seconds to load up and everything opened up all at once.
What i tried:
My hardware is all fine,temps are good, i cleaned and reinstalled new drivers so it should not be a hardware issue.I reset my router/modem and plugged everything back in. I will see if this fixes it but does anyone have any guesses as to what my problem is? Reinstalling Windows will be my last option.
