Q: WHEN I LOOK TO CHANGE THE SETTING IN THE SOUND AND SPEACH IT SAYS [NO OUDIO DEVICE] WHERE IT GONE THEN AND HOW DO GET IT BACK
A: hi meme from the description you have given this plainly indicates your sound driver has even been removed or has become corrupted theres several methods in getting your sound driver back,the first is to download a new(and updated) driver from the manufactuer ,however before you can do this you need to know the manufactuer of your sound driver and the correct driver to download to do this you need to download a diagnostic program called "belarc advisor" from http://www.belarc.com/free_download.html,unlike other programs of this type this one will tell you your p.c,s hardware without the drivers being present after downloading and installing belarc advisor scroll down the page until you see the audio/sound device and then using this information run a search to locate your soundcards manufactuer and then you can locate the downloads area on the website and download the appropriate driver another method is to use your motherboard chipset drivers,these would of come with your p.c however many people lose their disks so this is sometimes not a option,however if you still have your use this,insert the disk and locate the audio driver you can in theory run a system restore,since you probally had your sound a week ago,so go to start>programs>accesories>system tools>system restore>and choose to restore your computer to a earlier date>then choose a point around 7 to 10 days ago since windows uses the settings saved on that particular day(when you had sound) as soon as the restore has completed your p.c will reboot and you should have sound finally a common reason for loss of audio is when you use certain messenger and skype headsets and audio devices,so when using these types of devices allways go to the audio and sound settings after and make sure no changes have been made,if so go to the audio tab and then in the playback section using the drop down box select your default audio device note: the majority of p.c,s use onboard audio set-ups and as allready mentioned these are part of a chipset driver,however one of the most widely used intergrated sound devices is the "realtek ac-97" sound device i have 3 pc,s in my flat and every one has a realtek sound device,so it may be worth checking for that first any problems let me know good luck meme !
