Hi,
Just recently, my screen has been showing up with pink and green dots in that snow pattern seen on TVs. This isn't seen on the external monitor. At one point, I was putzing in BIOS and it was fixed, but then suddenly started acting up again when I removed the VGA cable. I think it has something to do with the LCD screen cable. I hope it's not the screen itself. I have yet to open up the computer to visually inspect the interior.
