ok i'm going to start from the begining and hopfully i can get some help. yesterday when i got home from work i logged into my computer and started playing my game World of Warcraft. about an hour into the game my computer just shut off. i tried to reboot it and when it got to the desktop it just froze. i shut it off again with a hard shut off and when i tried to turn it back on all i get is this buzzing sound and nothing. i let it go all last night and tried again this morning before work and it did the same thing. it doesn't load anything and the screen stays black just a buzzing sound that buzz about 3 times then stops and still nothing. just hopeing i can get any sort of assistance for this. i'm running windows vista on a xps system from dell of course. thx you
