Loopy graphics driver problem

  1. Hi everyone,

    My old Leadtec Geforce TI4600 died recently and I've replaced it with a Gigabyte 7600 GS.

    I'm having all sorts of problems installing the new drivers. If I use the installation disc I get 'Invalid Data' at the end of the installation.
    If I download the latest drivers and install them, when my PC reboots it's as if nothing has been installed and my pc prompts me to go through the same installation routine?!

    I removed all the old drivers before hand. I had heard of some issue with old Leadtec products and registry security settings - not sure if that's the issue.

    My motherboard is an Asus a7v8x with a via kt400 chipset.

    Any ideas chaps?

    Thanks in advance.

    Make sure you have a sufficient power supply. That's a big difference in cards (like GM to Mercedes)(Not to badmouth GM or anything)

    It should say on the box it came in. I'm not sure offhand. Probably between 300-450watts.

    I finally found the issue and it was to do with an old installation of a Leadtek graphics card.

    Basically I had to go to the following folder in my registry:


    and set the permissions to all the VEN_??? files to allow full control to everyone.

    As soon as I did this the Graphics Drivers installed without a hitch!
