    I was playing WoW the other day and the screen turned purple with white lines thru it. Never had the problem before. Now its starting to effect me just during web browsing. And when i happens the computer needs to do a system restore to get it back. I noticed that the main thing they restore does is revert it back to a state where the latest nvidia drivers are not installed.

    I was wondering is this an issue with the current drivers? Or has anyone seen this?

    It's not the drivers, your GPU is dead. It has a known fault.
    The BGA solder cracks and the connection from the board to the chip is broken.

    The problem goes away when you uninstall the drivers because without drivers the CPU is doing all the work.

    Google "faulty 8400m" or "G86 core fault" and you will see.

    Yea that was what i had figured had happened. Makes sense. Did nvidia ever do any recalls? or just hung us out to dry on that one?

    I think they paid a lot of money to companies like dell, sony, apple...

    So really it's up to those companies to give you a replacement or whatever.

    Yea ive taken it up with HP before, but apparently my model wasnt listed on their master list or something. It works well enough as a basic web browser and word proccessor tho. So at least i can do my school work till i can afford me a gx640.

    You should backup your data, just in case it gets worse.

    You should contact HP. For my Vaio FZ with 8400M GT, Sony had provided a 3 year warranty extension for the Nvidia GPU.

    Speak to a higher level person, not the bottom level customer service people. Windows 7 doesn't have to do anything with a defective hardware.

    Yes i did, and that person just told me they would be able to "sell" me a "New" laptop at a reduced price,

    They started listing off the specs i just laughed at them. I spent nearly $1200 on this laptop, im not gonna replace it with a Intel GMA piece of crap for $800 bucks. They couldnt even tell me what processor it was, just said "2.1 ghz"... Then when i told them that wouldn't be acceptable they said well thats all we can offer, is there anything else we can do for you? To which i said i guess not and hung up. Im not gonna play the whole "lets see who can outlast who" tech support game. I dont have 3 hours to sit on the phone until someone finally submits and offers to replace/fix it.

    I can promise you this i'll never buy HP again. Defective Nvidia part or not other manufacturer's have stepped up. Except them. IE limiting their response to only laptops with AMD chips. And I wont be buying an Nvidia card either. Not the first fail card of theirs I've owned. So MSI Gx640 here i come!
