We were given a used computer, CHECKED it for any problems, none found.  The computer is HP 2.6 G processer, 40 Gig HardDrive, 512 RAM.  

Have tried to install Windows XP Pro several times but each time we install, we find that in the System Properties, under Device Manager in the cat. "other devices" the Ethernet controller, Multimedia Audio Controller, Universal serial Bus (USB) Controller, and the Video Controller (VGA compatible are missing and show up with a big yellow question mark.  

We have tried to find the DRIVERS and controllers on our other pc to download onto disks and seperatly install them but that doesn't work either.

We have tried everything we know how but cannot get these drivers or controllers to install.  

Any suggestions?  Please help!I would format it and reinstall your operating system.

Thanks Sandra,  but we've tried refromating more than once but each time we install the Windows XP Pro, same results, missing controllers.  That MAKES it impossible to hook up to the internet, among other things.

I'm wondering if there is something on the hard drive that we have missed, or couldl possibly be blocking the full installation?I thought that would have fixed it, maybe your hard drive is DAMAGED, maybe you need anew one, the expert guys are great on here i'm sure they will come up with something.

Good luck
Go to bootdisk.com and download the CORRECT version of xp boot disc's and install from there. There are 6 floppys that will install all necessary drivers for an easy install of xp. Quote
