I think Nvidia Grapichs Chip Over Heating & Dry Solder Problem,

Based on your statement its like the laptop is booting normally but there is no display. Common problem on HP is their poor design on cooling system. In your case I would say the video card has reach its full extent. But you may want to observe this:
If it has a dedicated video it probably have a secondary fan for it, check if its rotating, if not then it caused the video to overheat.
Unless you know how to tore apart your laptop, you will not be able to further check this. Better send it to a service center.
I assume you mean video card instead of video drive. The nvidia GPU ( Graphics Processing Unit ) is built into your m/board. The only way to upgrade from say 256mb to 512mb is a m/board replacement. If you have a GPU failure ie failed graphics out put forstly test to see if the output to external monitor works - do that by pluging and external monitor into the vga port located on the l/h side up near the power on button - if there is no putput or it has coloured vertical lines your graphics chip is failing. the only rectification is m/board replacement. Hp has just recently trashed a huge number of defective m/boards in the pavilion dv2000/dv6000/dv9000 & presario v3000 v6000 range and had them remanufactured to correct this GPU failure
The mainboard or motherboard is the main PCB in the laptop. It is the most difficult component to replace because you must completely disassemble the laptop to remove it and properly install the new one. Take the battery out, ground yourself and discharge the laptop by pressing the power button for a few seconds. Most laptops start dissassembling by removing the power button/led panel above the keyboard, and then removing the keyboard, de-attaching the LCD screen assembly. And then flipping it over and removing screws on the bottom, then the laptop will split in two peices, the top part of the chassis and then the bottom half which is where the motherboard will be attached. If you decide to continue organize your screws, label them or take pictures to help you get it back together. Hope this helps you get started.
