I recently formatted my inspiron 1525 laptop and installed XP professional.
i installed all drivers by downloading it from dell site.
Even after installed Graphics driver for Mobile Intel GM965 and sigmatel audio driver am getting a driver not detected symbol in device manager.
I am able to hear sound when I play songs.
For audio driver , I did other suggestions found on internet forums like install system driver then chipset then finally audio driver etc… nothing worked out for me…
Finally I have installed R180043 and R180044 also…
Regarding Display drivers I have installed GM965 drivers downloaded from dell site.
There were 4 error popup while installed stating some .dll file image is not valid.
I tried to uninstall it but its not uninstalling too… shows error messages and terminates the process.
Any software that requires the graphics driver are not working too…..
Here is a link for manual reinstalling Windows.
It goes over details on what drivers should be installed and in the order that they are installed.
From your post I would look to see if the chipset drivers and dell notebook system software was installed.
