hi i have a xfx hd 7770.the card had to be replaced once before and now i am facing the exact same problem with the replaced card.i was able to play games for about one month with the replaced card until suddenly i started getting pixealated screens or green/red lines.when i did a restart the monitor kept showing no signal.this exactly what happened with the first card before i replaced it.is there something wrong with my machine?
