Momentary Freezing / Hanging - Slow Performance

I have updated to windows 8.1 and recently i have having a lot of problems with how slowly my computer is running. May i say I have spent a lot and I mean a lot of time trying to fix this problem and I know it has nothing to do with disk space, viruses or drivers. This has been messing with my network adapter and has been giving me gateway accessibility problems even though there is nothing wrong with my connection proof being that if I diagnose the problem in my adapter it resets the adapter just to have the same problem later until reset it again and the connection and all my devices is fine.

This problem includes a momentary cursor pause at random times that only effects my trackpad if i plug a mouse in it works while my track pad is non functional, this can last from anywhere from usually 2-10 minutes until my trackpad becomes functional again. im not even getting "not responding" messages when it when it freezes at random times, i just have to wait until i hear that chime that sound like it comes from an information box then everything goes back to slow again and barely functional.

This problem includes playing media, being that when i play media it takes anywhere from 2-15 minutes before it starts playing, this media can be from playing music and videos on my hard drive to videos on youtube. When I start up my computer it works fine for a bit like 5-10 minutes then starts being slow again with sending information to execute actions (mainly media actions), i even get a lot of loading issues on skype. Even more to my conviction that its the operating system causing the problem is the fact i had my computer working normally for a week at random just with the gateway connectivity but all files I executed in the times quickly like they were supposed then with another boot sometime later it went back to being slow again.
