the speaker icon in the bottom right hand corner of my screen has started to display a red circle with white cross and when the mouse points to it, it displays the message "No audio output device is installed".
I've not installed anything new (software or hardware) and everytime I restart my computer it fixes itself but then develops the fault again - help please!
My pc runs using Vista home premium if that helps?
1. OPEN YOUR "CONTROL PANEL"...THEN OPEN "HARDWARE AND SOUND" 2. LOOK FOR AND CLICK OPEN "DEVICE MANAGER" 3. SCROLL DOWN TO ' SOUND,VIDEO AND GAME CONTROLLER' 4. RIGHT CLICK "SOUND VIDEO AND GAME OPTION"...THEN AN OPTION WILL COME UP SAYING..."SCAN FOR HARDWARE CHANGES"...CLICK IT AND HEY PRESTO...YOUR SOUNDS AND VIDEO AND EVERYTHING IS WORKING!
