My computer was assembled about 6 months ago.Recently it started displaying unusual lines which flickers and makes the monitor display shake.I sent the cpu for repairs and the man told me that the lines were due to loose hardware connection.Now the lines have shown up again.Please help me to solve this problem .Please.............................................................
