Re: DRIVER NEEDED: Acer aspire 5100 (Windows XP Professional)
If you cannot find proper driver from Acer website, you can download driver through device manager.
Step 1. Click Start, then right-click "My Computer" (or "Computer") and click "Manage".
Step 2. In the Computer Management window, on the left, click "Device Manager".
Step 3. Click the "+" sign in front of Mouse and other pointing devices.
Step 4. Right-click the device listed below Mouse and other pointing devices and select Uninstall.
Step 5. Click OK to confirm removal of the device.
Step 6. Restart the system. Windows will detect and automatically install the driver.
If it does not help, you can use this drivers download utility to download drivers automatically. With it, I have downloaded and updated many drivers. tiny.cc/3cwerx. Hope it can also work for you. Download and install it, then it will automatically scan for your system and recommend suitable drivers for you. You can download or update whichever driver you need.
