Screen resolution changes from 1024x768 to 800x600

I am rolling out a new Dell Optiplex 760 desktop to our estate. The OS is a preloaded WinXP image that has been created for a Dell Optiplex 755 and 760 series pc. Over a thousand 755 pc's have been rolled out with no issues. We have started deploying the 760's to an area of our estate and are finding the screen resolution randomly and intermittently changes from 1024x768 to 800x600. We have a number of different models of crt and tft's and all are experiencing the issue. We have been informed that there is a new Intel chipset and video driver for the 760 pc, but after applying the updated drivers the screen is still changing randomly to 800x600, the user can change the settings back but the problem persists. Has anybody seen or heard of this problem?

    Hello Uncle Chunky, I have seen this problem once before and it is generally very rare. It normally has to do with the specific order the drivers are installed in (I understand that this is a Image that you are loading with). Once this starts happening you can update the driver, reinstall it, and disable/enable it but the problem will remain. I know you don't want to hear this but I would try to re image the machine if possible for some reason something didn't take. If this was just a standard install you would be left with no choice but to reinstall Windows and then reinstall the Drivers. As I said this is very rare and you probably will never see it again. Hope this helps.

    Your welcome, and I hate that was the answer I had to give, because generally there is a way around having to do a reformat or re image. However, the one time I went through this I ended up doing the same thing as an end result.

    That's fine, however if you do find something else yourself please post it back here because I would love to know myself having gone through this once already.

    Have found no answer to this problem. In discussions with the vendor. Closing question with solution at present.

    I was having the same issue on several Optiplex 760s. The only solution I could find was to completely remove the Intel video driver and use the default WinXP driver. I disabled the card in Device Manager so that the New Hardware Wizard wouldn't pop up every time I rebooted. Seems to be running fine now.
