took off the old antivirus they had on there and? now when it reboots..it cuts off and keeps restarting and cutting off. It was just fine until I got rid of the old so called anti virus. I tried to boot in safe mode..in ever other mode by pressing f8 when it starts..but it keeps showing a blue screen "saying something about memory" for 1 second then it reboots again....I havent even had this computer for a whole half of a day yet and this happens and I dont have any more money to spend..can someone please tell me what I should do cause it goes straight to the main screen..goes to the windows xp screen...then it blinks out and goes back to rebooting...
