Game deteriorating

[Maliant]

The game used to always run fine for me... All of a sudden the game got really choppy when I have logs on. Then the mouse look stopped working, mouse control is activated and sometimes it moves but it's all choppy and unreliable. Now as well I can't right click items to see stats / item charges. Anyone know what's causing this? It basically all started happening a few weeks ago, PC has been restarted and even shut down for the entire memorial day weekend, came back and the issues are persisting.
