|Hi Subhash,thank you for your reply.|
I cannot recall loading any new software or drivers. I am reluctant to load software as the harddrive is quite full.I had been using an updated version of Adobe Audigy the night before?I updated this software some days ago but I have been on the net more than usual.
I do not have the original cd of XP Home as this was pre-loaded.
The computer is a Delll Dimension 4600, Pentium 4, 2.66 gz upgraded to 2mb of ram.I cannot believe this has happened as I am running Avast, Prevx and Zonealarm.Thanks.
