I'm not sure why, but my computer screen from time to time will start to show yellow, black, gray, and white lines in one area, like "start" and when I click it will sudently show more lines, and I can't see anything. It sometimes goes away when I turn my computer off, but not always.
This just sudenly started happening and I have no idea why. This computer is less then half a year old.
Is there any suggestion for me to solve that error? Thanks in advance.
