KAV60 motherboard are also used in Acer One D250. Just go on Acer website and look for it.

IF you have a Recovery Partition, you can do a Factory Recovery, returning the Laptop to the day it came out of the box. Take a look at the eMachine website for info on a Factory Recovery from recovery partition: http://emachines-us.custhelp.com/app/answers/detail/a_id/29934

RTM - Read The Manual

Get onlineand got to www.google.com In the google search box type: "AcerSupport" (without the quotes and put your manufacturer name before Support). Look for downloads and drivers. Enter your model number and operatingsystem when requested. Look for Manuals and search them for Factory Settings or System Recovery.Also I thought Acer supplied something in the Program List or Control Panel that was called eRecovery. if so launch it. Click Start/Programs and look for eRecovery. if it's not in the program list click Start/Control Panel and look for eRecovery.I found the excerpt below in the manual online.Launching Acer eRecovery Management

Note: The above drivers are for Windows XP.

It's a very good possibility. Most the motherboards are mass produced by a few companies. They just make a few alterations for different brands, models and configurations. Your only major concerns would be if the back plate would match and wether or not you have a proprietary power supply. If your power supply has a standard 20 or 24 pin configuration it should work.

Please reinstall the webcam drivers. Please follow the steps below:
Click on START>All Programs>Emachines> eMachines recovery manager> Restore application and drivers> Select camera driver (Chicony, Sukiyan etc) and click OK or install.

There is a software disc that all drivers are free gift from Emachines, provided that this CDs is still on your hands.
Use that Software Disc Utility to install unknown LAN or Ethernet Device in your Emachines Desktop.
If your don't have that Disc then you download that freeware LAN drivers to the website manufacturer of Acer Emachines.
Or maybe you don't finish yet installing all devices such as VGA, & etc...
Click this link to open browser: www.acer.com
It's very easy to find out there.
Good luck!
