compaq presario v6000 motherboard causing overheating issue and shutdown of computer Internet

Call Compaq and find out if your GPU is still covered under the recall from Nvidia.  Several thousand laptops have a faulty GPU which overheats and disconnects from the board.  If you call around to computer shops, some places do repair them for under 100 dollars, but Compaq may offer you a motherboard free of charge.

There really isnt much you can do at this point. Its either fix it or get a new computer. 4 years is a long time for a laptop to function anymore. You are well outside the expected and warrantied lifespan of that computer. Its not defective if it took 4 years for the problem to manifest, thats why there's no recall. Most computer manufacturers warranty their computers for 1 year, so any breakdowns over a year is normal.

No ripoff here unfortunately, just an old computer.
