I repaired a Compaq F700 yesterday with the same symptoms. It's the video chip.

Yes I would agree, video chips of course get hot and if the heat dissipation is not good, for whatever reason, bad air flow, poor chassis design then the chip will get so hot it can melt the soldier and pull off the board or create dry joints.
Options are: Re-flow the chip with a modded cooling system. Re-ball the chip, expensive! New motherboard or graphics card. Beware though there are A LOT of models that have inherit problems so if it has happened once it will happen again! |

This is a common issue especially among these compaq (HP) laptops with the nVidia or ATI chipset.
If you don't own any reflowing equipment, literally pop the motherboard in a household oven for 8 minutes at 230C Let it cool undisturbed for one hr. |
