    Hi. I've got a Sony Vaio SZ435N/B which has an Nvidia GeForce Go 7400 GPU. I rarely use this for games but occasionally I do and to get things running smoothly a few weeks back (while running Vista Business) I downloaded and installed the 174.74 driver and everything seemed to be working great.

    Then last week I went to fire up one of my games and found the graphics all screwy, so I checked Device Manager only to find that my display adaptor was reported as being a Mobile Intel(R) 945GM Express Chipset Family!

    I tried switching back to the Nvidia 174.74 driver, failed, and decided to stop procrastinating and revert back to Windows XP.

    I've now got XP set up with all the other drivers apparently working fine but now Device Manager lists two(!) Mobile Intel(R) 945GM Express Chipset Family devices under my Display Adaptors.

    Device manager reports the hardware ID's for the two devices as:

    PCI\VEN_8086&DEV_27A2&SUBSYS_81E6104D&REV_03
    PCI\VEN_8086&DEV_27A2&SUBSYS_81E6104D
    PCI\VEN_8086&DEV_27A2&CC_030000
    PCI\VEN_8086&DEV_27A2&CC_0300

    and...

    PCI\VEN_8086&DEV_27A6&SUBSYS_81E6104D&REV_03
    PCI\VEN_8086&DEV_27A6&SUBSYS_81E6104D
    PCI\VEN_8086&DEV_27A6&CC_038000
    PCI\VEN_8086&DEV_27A6&CC_0380

    Can anyone explain what happened and help me get an Nvidia driver working again?

    Thanks in advance.

    Just to make sure for you, is your notebooks Speed/Stamina switch in the Stamina mode? That seems to be your issue, but I may be wrong.
