I don't have anything running in the background during play as previously I discovered it made my game run much slower, and every program that can start on booting has been disabled in Task Manager.

The game is installed on a separate hard drive due to the limited size of my laptop's own hard drive preventing me from installing larger games on it. However this is still the only character affected - if this is a possible cause of the problem, is it possible my other characters will also run into this issue at level 70+?

Thanks
