I have updated the graphics drivers, I have DirectX 9.0c and i have tried re-installing the game. Sadly, none of these things helped.
The only error message I've had said that the program had crashed and the application was closing. This appeared as I was Pressing the start button on the computer to close it down. Usually, the music either stops or hits the same note repeatedly. The only thing I am able to do then is close the machine down by pressing the on/off button for the required five seconds.
I think I've got it sorted. It seems to have been the swap file. I had it set to no page file, thinking, foolishly, I now realise, that Windows would set it at the 2Mb minimum it says it must have. I have reset the thing and everything seems to be fine now.
Thanks again for the responses
