Ok, I am a broke college student and I emphasis the word broke.
I have a Dell Inspiron 9300 Laptop that has been refurbished... therefore my warranty was only 2 months and its past the date. I had this 1 line through the middle of my computer but now it has recently turned into 3.
I'm not horrible at maintaining my laptop but I have accidently dropped it by a foot once and I keep it on my bed and desk. However, I really don't think that's the problem.
Here's a picture below:

Well crap, the picture doesn't show the lines. But there are two cyan (light blue ones) and 1 red one. They seem to be dotted (pixelated) but from afar look solid.
Please please write back here at what the problem is or email me back at xxxxxxxxxxxxx If I have to replace something, I could use suggestions on who to contact or what to get. I live in Dallas, TX.
Thanks, Suzy.
