My pc is qite fast but lately its been acting up nothing really seriouse just my internet, if i use one of my browsers, then close them i cant use them until i restart, its pretty annoying, any way i want to completely restart my pc but i dont want to have to reinstal certaint things like verizon dsl and my Gunz game. everything else can be redownloaded although re-downloading 130 something eps of naruto will be a pain but its no biggie. any way is it possible to do this
