Ok, I’ve not searched for an answer, yet, I’m just going to give you some tips on what you can do. You could try clearing up your registry and other files on your computer using CCleaner which will also allow you to check all the programs installed on your computer (more so then the Microsoft Add/Remove programs utility) and my final tip for now is to look in your startup programs list (Start Menu > Run, type msconfig and run that, check the startup tab AND the services tab) and try all of that, I’ll try and look for a solid answer if it’s noted anywhere in any bug databases as well :)
