Hi all, I was using my computer today, and all the sudden, my monitor started to behave strangely; A "wave of collor" (thats the best way I can describe it) came across the screen and the the screen was a dark blue shade with a vertical black line running through it. The line moved with the mose, but I couldn't see anything but the blue collor and th black line. At first I thought it was a bad connection so i unplugged and re plugged it into the tower. After a while, I gave up and shut the monitor off then left for about an hour. JHust for kicks I turned the computer and monitor back on and it was working again. Then after using the computer for 20 mins or so, the same thing happened. Any ideas on why this is happening or how I can fix it?
