You can download the LAN, Wireless and device drivers from Dell WEB site, the support download page. Make sure you select your model desktop or laptop, better still, type in the Service Tag number, it is printed on the label on the bottom of the laptop and on the back or sides of a desktop. (If the Service Tag label is missing then go into the BIOS setting and on one of the BIOS pages, the Service Tag number will be displayed). This will open the page where the specific drivers for your model computer are located. Also make sure you select the Windows of the drivers for your Windows operating system.

You will need to format the drive and download the drivers only after a anti virus software is installed. It is possible that there are errors within and so will be best to check the OS once again for faulty files , if so it must be reinstalled.

Camera is not detected, there are several possibilities:

The first possibility
There was an error installing the driver. AOD150, manufactured by three types of cameras, chicony, liteon, suyin. Example: I installed the camera driver, suyin to AOD150. At the time of installation, a message appears, hardware not found / not detected / not recognize. This means, suyin not the right driver.

Solution
1. Open link driver AOD150
2. Operating System = Microsoft Windows XP Home Edition x32
3. Download software = Hardware Vendor Detection Utility
4. Double-click = HWVendorDetection.exe. We will find the right camera hardware.
5. Download and install the Liteon driver





The second possibility
If the hardware vendor detection utility, does not detect camera

Solution 1 (assuming, normal hardware)
1. Possible corrupt operating system.
2. Reinstall the operating system, by doing format drive C.
3. Move all data from drive C to D/E/F.
4. Download drivers AOD150, and other applications, save it on drive D/E/F
5. Insert the Windows CD bootable. Perform boot from CD.
6. Press enter - F8 - New Installation - format the C drive, etc.
7. After the OS install is complete, install all drivers (chipset, LAN, VGA, sound, camera, etc)

Solution 2 (assuming, damage hardware)
