Sorry if this is in the wrong section, I'm not very good with computers and I don't know what's going on. Ever since a few days ago, every two hours or so my computer just starts freezing a lot for about an hour. For instance when I open a new tab in Chrome the whole program stalls for about 10 seconds and I'm not able to click anything on any other program either. Programs are also extremely slow when opening and closing them and they sometimes also cause the freezing. Like I said it only happens every two hours or so and lasts for about an hour so sometimes this issue is extremely inconvenient and sometimes it doesn't happen at all and my computer runs perfectly. I've run Malwarebytes multiple times and deleted everything it detected to make sure it wasn't malware. Could anyone help with this, because unfortunately it prevents me from doing my job.
