Monitor Screen Blinking Colors

[michelles2]

When using my HP monitor, the whole monitor screen suddenly began to cycle through five different colors repeatedly: red, blue, green, black, white. This began a few days ago and continues after about an hour or so of monitor use. The monitor is plugged into a Panasonic laptop via a DVI cable. 

No software or driver changes have been made recently. Sometimes turning off the monitor and turning it back on will stop this cycle, but sometimes it will not. What could the problem be?
