OK so i got this brand new Toshiba Satellite pro C650 Series for Christmas . And i also play xbox at first everything was working fine. But then one day i turned on my xbox and the music i was listing to became really slow. And everything on my computer was acting slow even when i was turning it off it was still SLOW!So i found out that whenever i have my xbox on my PC will run slow so i figured that i cant have both on at the same time. But then a few weeks later it stared working again, i could have the xbox and PC on at the same time but that only lasted one night. And my mothers PC witch is made by Toshiba but its a different model and this does not happen to her PC. So can someone please tell me whats going on and how to fix it!
