Whenever I play video games on my pc, after a little while, different parts of my screen start turning red, and it makes gaming on my pc almost intolerable. Any thoughts on what the problem could be? There has been a new development, I got a second screen and when the original red screened the other was fine. Why would this happen if it was an issue with the graphics card?

Provide graphics and other hardware details, or at least exact laptop model. –  Karan Feb 18 '13 at 4:40

HP is notorious for having bad cooling designs on their laptops. If it's under warranty contact support, otherwise clean any dust from the inside and try re-applying the thermal paste. –  danielcg Feb 18 '13 at 4:45

See this page. Certainly looks like these are known for GPU failures. –  Karan Feb 18 '13 at 4:47

When I see single-colour situations with a desktop monitor, I suspect display-connector issues. Can heat cause ribbon-cable to shrink/retract from contacts on mainboard? –  Solemnity Feb 18 '13 at 6:23

Sounds like an odd temperature-related problem. If the laptop is under warranty, get it fixed. If it isn't, experiment with some cooling of some sort. What's the model? Have you searched to see if others have a similar problem?
