Hi.

It will take 2 mins from you to install...
I hope I have helped you...

First check up your device manager > right click my computer > choose properties > click hardware > Device manager > check up sound, video and game controllers for driver(note:if you see in the sound device have yellow question mark), you need to install software driver for that gadget.
also try to check-up your speaker headset sound output for loose adaptor and hole.

Hopes can helps.
Thanks for using Fixya

If Veo has updated drivers for Win 7 you would have to download them from the Veo site.

As per the DELL web site there is no driver provided for Windows XP , Check witht DELL technical support.

Go ahead and install SP3 for XP. This should resolve your video and sound issues. For the other items load the appropriate drivers.

you cannot downgrade from Vista to Xp unless you format your hard drive or install xp on another partition check your device manager for yellow marks on sound devices and update your sound drivers

hi,
this is one of the most common problem while downgrading from vista to XP.. get the driver of your sound device...now u can't directly install the setup it wud display no audio device... so do the following...
1. Righty click my computer...click the hardware tab..
2. click device manager... now you will see a yellow mark on the uninstalled audio device. right click on it and update driver from a specific loaction( where you have downloaded your audio driver ).

this would work...but remember to install the microsoft unversal audio architecture before this.

hope to get rated as fixya!!!
