Cleaning Your PC
If you start up your P100 one day and notice that the screen is behaving erratically, images are distorted, it gives you a blue screen of death, or things are visually unsound, then there's a three-step process you'll want to follow to try to locate and fix the problem: Clean, Install, Replace.
Clean: The first thing you'll want to try and do is as simple as taking apart your laptop and unhooking, cleaning, and re-attaching your video card. Okay, maybe it's not as simple as my article is making it sound, but it's more than doable. What this will require is a screwdriver, a plastic spudger/butter knife, a screw tray, a knowledge of what the video card looks like and a knowledge of taking things apart. If you think you've got all these things, do some Googling to find the proper procedure and then have at it. Don't get too concerned about difficulty. Most Satellite part replacements are very simple to do.
To clean a piece of computer hardware, normally a cotton swab and some rubbing alcohol will do, but don't just put it wherever you want. Make sure you only clean the parts that have dirt,dust, or grime built up on them. Then reconnect the card and start everything back up.
