Restart the computer If it does not work, it seems that there is no built-in driver for this audio component. Check "Delete driver software for this device" check box, click OK. Right click your sound card and click Uninstall. Double click to expand "Sound, video and game controllers". Click the Start Button, type "devmgmt.msc" (without quotation marks) in the Start Search box and press Enter. You can also try reinstalling the sound card driver as below: Reinstall driver = 1. Browse to the folder where you saved the downloaded driver, and click OK. Check "Include subfolder" box, and click Browse… 5. Select the " Browse my computer for driver software". Right click on the device and click Update Driver Software… 3. In Device Manager in the search bar and press Enter. You can also try installing it manually: 1. If the Vista driver for this model is available, try downloading and instaling it. I did not find model 5070 on acer website. The second device should be an audio component. I run Drivereasy to help with the drivers after I installed Windows 7 and it worked for everything except those 2 drivers. I am not a techie and have no clue what the missing drivers are or where to find them.
I did it and my laptop works beautifully, it's better than ever, it's more like I gained a new computer.
