Every time i try to play a game my computer gets these weird little lines on the screen then goes back to normal and says ati radeon family has stopped responding. I have taken it by a computer repair center recently where they replaced my hard drive. Ever since i got it back it has been doing this. They replaced the cooling system. Re flowed everything ,updated the driver and reinstalled windows 7. Monday there going to see if downgrading to vista will fix the problem i need advice or need to know if this is a common issue with people.
