Thread: Monitor turning all different colours while playing games.

I play games on my computer and sometimes my screen goes black and then it goes through a colour cycle of red, green, blue and it keeps going through this cycle and will not stop until I power it down. Please help me to get rid of this problem. Thanks in Advance.

My system specification:
Intel core 2 duo 2.1 GHz
2GB Ram
160GB HDD
ATI mobility Raedeon HD 4670

The signal is delivered to your monitor over three separate wires for Red, Green and Blue components of the color. One of these wires most likely has bad contact so your colors are jumping around. Twist the video cable plugs on the computer and the monitor; see if your colors change as you do it. If they do, you may require changing the video cable / video card.
