Since about 5 months ago I have lost sound from the PC.
I was told that there was no sound driver and this had to be installed. This was done remotely and worked for a few months and the problem reoccurrred.
This time the driver was not able to be downloaded and installed remotely.
(It may be that the PC came with Windows Vista and it now has Windows 7 - has had for approx. 2 years and had no sound problems.)
I was then advised that it was not a software problem and that the PC needed a sound card and I should have this installed.
When I took it to a PC repair shop software was downloaded and installed and I was told that no sound card was needed. Again this fix worked for about 6 weeks and then - no sound.
Help!
