Maybe we can walk through and find the drivers from the manufacturers... 1. Right Click on My Computer, Left click on Manage. 2. Click on Device Manager, you should notice on the right hand side icons with a yellow symbol next to them, this shows the device is unknown, or drivers are not installed. 3. Right click a device you are looking for, left click on properties. 4. Click on the Details tab on the top of the menu that popped up. 5. You should see some code in the middle that looks similar to this: "PCI\VEN_14E4&DEV_169C&SUBSYS_308&" The important pieces are: VEN_14E4 is Vendor 14E4 DEV_169C is Device 169C for Vendor 14E4 You can take this information to the website http://www.pcidatabase.com and find the specific device information for the drivers, then go to the manufacturer website and see if they make drivers for Windows XP, some hardware is Vista specific and the manufacturer's do not have driver support for Windows XP. *Once you are in the Vendor and are searching for the Device you can hold CTRL and press 'F'. -This is the Find feature, type in the Device ID and it will find it much quicker, since some pages are quite long.
