My 14 year old son was given a hot 'n heavy computer last October as a birthday present (bad idea by grandma). While still under factory warranty, attacked by trojan horse virus (Adaware & Spybot only at that time). Geek Squad reformatted hard drive and all was well. I then installed Norton 360 and all was well until the other day when he took it upon himself, without telling me that Norton Internet Security had a problem, uninstalled Norton 360 and installed and paid for BitDefender. Once Norton was uninstalled and/or BitDefender was installed, his computer stopped working. I then took it to Computer Stop and once again they reformatted his hard drive. He just got it back, and immediately uninstalled Vista's sidebar (gadgets). Guess what, his computer is shot. Blue screen of death, the whole enchilada. The computer booted up fine at the repair shop. Other than taking the Alienware away from him until he's 35, what is with Vista and uninstalling the sidebar/gadget option? Not sure what specs to give you other than I know that it cost $2,000, including 19" monitor and 5 speaker surround-sound. Help me PLEASE!!!!
