inspiron 9300, windows xp, display started showing 2 thin vertical lines, over the past few weeks lines have been added and now there are several colored thin lines and one thick white one; if computer is on for a while the right side of my screen starts fuzzing of and on, is this a self fixable problem?1 person needs an answerI do too

You can try buying a more expensive monitor. In my experience, this usually fixes the problem. If that doesn't work (or you can't afford to buy a new monitor), you can take your computer to a local Best Buy. To the best of my knowledge, this is a fairly common problem (this happened to my dad's computer).
