I have a Hp Pavillion DV9000. Screeen ahs lines up and down. Also once when it does come up , whenever it wants to it will shut down on its own. Sounds like the mother board , but not sure. HP want 100.00 dollars just to talk to me then 350.00 dollars to be diagnosed. Anyone have any info. Thanks email@example.com
I would start by downloading speedfan and checking out your temps. if you are running hot first try cleaning the fan and heat sink on top of your cpu. do not remove the heatsink unless you have some fresh thermal paste to use.
