AUDIO DEVICE HEADACHE!

[ABUSHAHEED]

My younger one tampered with my laptop over night.

after which whenever i want to initiate Windows media player it tells me

"WiNdows Media Player cannot play the file because there is a problem with your sound device. There may not be a sound device installed on your computer, it may be in use by another program, or it may not be functioning properly"

i tryed troubleshooting, but the device driver isnt coming up.

i also tryed the system information to verify the device and i found out under the component sub-category that the sound
and CD-ROM components were missing.

It also gives an error message "audio device on high definition bus"

The laptop maker is HASEE model F420S.

PLEASE KINDLY SEND IN YOUR URGENTLY NEEDED SOLUTIONS. THANKS

Did you try system restore?

Sorry if that seems too obvious, but it's the method of first resort.

I have actually restored twice, but to no avail.

Most likely you need to install drivers for your sound card. To confirm this, please check your device Manager (right-click My Computer -> Manage -> Device Manager) for unknown/improperly installed devices.

Please visit you computer manufacturer’s/soundcard manufacturers website, and download drivers along with the installation instructions.

I formatted my system and my audio device on high definition audio bus, Mass Storage Controller, VGA Controller, VGA Controller (VGA Compatible) are not installed. How can I retrive these drivers and install them for Hasee model F420S? Pls help me out
