Question How do I get rid of the red outlines in my graphics
Answer You'll need to explain the question a bit more as I'm not sure what you mean.
The basics are:
Buy some canned air and blow out the monitor (just blow out the vent holes)
Reset the monitor after it is unplugged for about 1 day (use the buttons on the front)
Remove your video card (if you have an add-on card) and reinsert it into it's slot
Install the newest video driver from the computer manufacturer's website
