Hi There, I was looking for some advice on how to fix my laptop. It is running Windows vista. I had a problem where i was trying to download a video file using a Firefox extension and the PC completely crashed and the user profile became corrupted. It wouldn't even log on in any mode so I got some help to create another profile. Although I have created a new profile, given it admin rights and transferred the key files from the old desktop across to the new one; certain basic functions are not working. For instance, it is not producing sound. I open a sound file and it is playing in the player on the screen but the speaker image in the bottom right corner has an 'x' (mute) sign next to it. When I scan over it with the cursor, it says 'the Audio Service is not running'. I right click it and go to sounds and a window pops up saying: 'This computer cannot play audio because the Windows Audio Service is not enabled. Would you like to enable the Windows Audio Service?' I click Yes and the Volume Control Applet alert comes up seeking permission to continue. When I click continue the Sound window opens showing the speakers listed as 'working' with a tick next to them. So I click OK and it closes, but nothing changes.... In addition to this the wireless connection finder is failing to start in a similar way. Guidance would be much appreciated.... Thanks.
