When you omit the interface and other important details, it's impossible for us to help:
1: Did this device come pre-installed in your computer at the time or purchase or did you purchase it separately then add it to the computer?
2: Is it an "integrated on the motherboard" device, a "laptop mini-card", or a "pci or agp graphics/video add-on card"?
3: Used in a desktop or laptop computer?
4: Motherboard/Computer brand and model?
5: Did it come from the factory with Windows XP installed?
6: What is the hardware id string (found in Device Manager, double-click the device, click the details tab, 1st. line of text). Usually starts with PCI\VEN......
If you're unable to provide accurate hardware info, I suggest using this program:
To find make and model of pc hardware, EVEREST Home Edition
is a free system diagnostics, system information program that will id most hardware on-board a mb. as well as the actual motherboard. It will, in some cases, actually provide a download link for the driver.
Alternate Everest download link: (offers 2 sites to dl program from)
Run the program and then:
Click on Computer
Click on Summary
Right hand window (hardware) if the text is BLUE
this is a link to the web site for that particular hardware.
If you have additional questions or need further help, please post a "copy and paste" of the COMPUTER SUMMARY report
(Leave out the Debug–PCI section) from Everest.
