when cleaning files from my computer i seem to have deleted something i shouldn't. I now have no sound and when I start realplayer it says i dont have a sound device. Cheked this in 'system information' and sound card is listed and 'ok'. Any ideas what could be wrong.

You probably need to identify the model etc and reinstall the drivers for it.

HI,
DEPENDING ON IF THE SOUNDCARD CAME WITH A INSTALL CD,IF IT DID JUST RE-INSTALL.IF IT DIDNT YOU CAN X/P SYSTEM RESTORE,OR YOU CAN SHUT THE COMPUTER OFF,TAKE OUT THE SOUND CARD THEN PUT IT BACK IN,RESTART,AND X/P SHOULD RECONISE IT,AND INSTALL IT.
HOPE IT WORKS OUT FOR YOU

thanks for your help guys, I think it seems to be sorted now,( just by rebooting) but still seems to be problems with some sound. I can play my MP3's again so thats the main thing ... thanks again.

if its films you cant hear then youl probably need the AC3 ( audio codec 3) you can get it here

Still got problems ..... It seems that I can get sound from files stored (Using windows media player) but cannot get any sound from the web??? MX says sound device is all working OK.

what sound card have you got installed
