    Graphics card problem

    Hello All,
    Looking for feedback on this issue.

    I have a four year old Toshiba Qosmio laptop, which is their "gaming" laptop, although I use it as a desktop replacement. It is running Windows 7 Home Premium and has an NVidia graphics card in it. About a month ago, a problem started where the screen goes black, and then recovers, and I get the message: "Display driver stopped responding and has recovered. Display driver NVidia Windows Kernel Mode Driver, Version 188.29 stopped responding and has successfully recovered." (188.29 is the version of the driver currently installed)

    Thus far, I have downloaded the graphics card driver (same version as was installed originally) from Toshiba's website, and used it to overwrite the existing driver. No joy - the problem still occurs.

    Thoughts, anyone? Is this a Windows issue, or is the graphics card going bad?

    All help is appreciated!

    Regards,
    Bob Miller

    Restore the computer to the date where this issue was not occurring. If the issue still persists then it is the graphic card issue.

    Hi robtlmiller,

    Not wishing to be the bearer of bad news but have you considered that the problem may be caused by overheating?

    It’s been widely reported that Nvidia has had lots of problems with graphics chip overheating for the past 7 or 8 years and it appears that your Toshiba Qosmio NVidia GPU is no exception.

    Originally, the problem was that many Nvidia chips simply expired through internal overheating, which Nvidia tried to sidestep by claiming it was caused by inadequate heatsink design, i.e. ‘It’s not us, Guv, it’s them!’

    Having claimed to have solved that problem it has now morphed into a new one where the overheating unsolders the graphics chip from the mobo or card causing ‘dry soldered’ connections. This new problem is particularly difficult to track down as the dry connections can temporarily resurrect themselves on cooling down.

    This intermittent connection problem can be cured by unsoldering the chip, cleaning off the lead free solder (the scourge of modern electronics) and replacing it with ‘proper’ 60/40 tin-lead solder. Definitely not a job for the faint hearted though – I speak as one who has done a couple!

    If you eBay search ‘Toshiba Qosmio (+ model#) NVidia Video Card’ you’ll find plenty of people selling refurbed cards and mobos.

    Hope I’m wrong about your particular laptop problem.

    MyHelpster, Thanks for your input!

    Chris, Bleeah (as Snoopy says) - I had considered the overheating issue and yes, you are correct - Ebay does have motherbaords . . .
