How can I fix graphics issues on a Windows 7 Sony Vaio?

I have a Sony Vaio VGN AR21S. It is a European model, which I brought second hand and I was unaware as to the problems of updates if you do not live in Europe.

It is supposed to be running Microsoft Windows Media Centre Edition 2005 as the operating system, but for some reason it has Windows 7 Home Premium on it. All Sony Vaio recovery files have gone, my screen has pink or sometimes green perforated lines running vertical on it. Occasionally, for a very short period, it will clear and be perfect, but alas it always returns.

    Sony Vaio VGN AR21S has known issue with Nvidia chips.
    I adv to go on Sony site and checkĀ  with your serial number to be sure.
    Sony can repair for you in warranty 4 years up your POP date.

    I suggest to backup ALL your data, try the steps described by FIDELIS and if those don't help head straight to the next professional.

    Pink artifacts usually refer to a problem with the graphics memory which could be either the 256MB discrete or shared memory. Together with the vertical green lines it is a "good" [well, actually bad] sign that your entire GPU is failing.

    At that point you will be glad to have all your backed up and ready to use on another system.

    These are the specifications for your sony vaio:

    Have you tried downloading the drivers from NVIDIA site? According to the specs your desktop replacement laptop uses NVIDIA GeForce Go 7600. According to the following link nvidia does not support sony vaio laptops you have to go to the manufacture's web site to see if there are drivers available. Check the link:

    http://www.nvidia.com/object/geforce_notebook_winvista_win7_179.48_beta.html

    Try this steps:

    - start >> type device manager in search box >>
    - right click device manager >> run as administrator >>
    - double click device manager >> find display adapter >>
    - highlight display adapter >> right click >> click disable.

    Run your computer with the display adapter disabled and see if the artifacts get better or disappear. If possible let the laptop run for hours and see if that helps. If your laptop does not have the problems you described earlier for a few days you can uninstall your driver and reboot. When the computer is finished restarting, Windows 7 will probably install a driver for you. Try that driver and hopefully will work better than the one you had before.

    Read this article about NVIDIA graphic problems. It includes you model.

    Here is a link for driver updates from SONY VAIO Europe. These are vista drivers and most times they work really good with Windows 7. If the link does not take you to the page, copy paste the link and open it in your browser:
