So I have been having some PC issues lately, and decided to do a clean install of windows 7. The only things I have installed on my PC are the drivers, updated BIOS, steam, Blizzard portal, CCleaner and Bitdefender. When I Start my PC up, the windows start screen appears, and then it rests on a blank screen with the mouse button for a minute before actually loading windows. Does anyone know what this means, or if it is bad/what I can do about it?
