Selfloading,
Thanks for your reply.
Having done some trouble shooting via the phone today we came up with the following.
With the 'Windows Task Manager' up it shows CPU usage to be between 12-28% with no programs running.
When opening another program (skype) CPU usage jumps up to 100% and stays there.
In the task manager under 'processes' the only 'heavy' users are:
APPSVC32.EXE with 0-13%
System idle process 85%
Everything else is between 0 and 1%.
However just came across this thread:

Could an increase in RAM memory solve the problem as there are now two banks of 256Mb installed. The max the computer can handle is 1024mb in 2 x 512Mb.
Thanks again, CEJM
