Display of horizontal lines
There was this thin 2-3 pixels horizontal line appear on the displayed middle of this month (NOV 2010). It was gone after I reboot the machine.
Today is the 2nd time the line appeared, but this time there were 2!! 1 in the center of the screen, stretched from almost left of the screen to the right edge of the screen. Another line at the bottom of the screen, stretched from the center to the right edge of the screen.
I got really worried. Anyone can please kindly advice? Your kind attention is very much appreciated.
