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?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
I had this exact problem, it ended up being a loose HDMI connection. When the screen is showing all the little red parts, try readjusting the HDMI cord. If it is indeed an HDMI connector issue, you should see the red turn back to normal instantly. Check both HDMI connector ends. If you're not using HDMI, check the ends of whatever connector you are using.
The way you can verify that this is the problem is by taking a screenshot, saving it to a file, then viewing it on another machine. If it looks fine on the other machine, then it is a connector or monitor issue.
