More and more frequently my computer just locks up. I can be using any program and can be connected or disconnected from the web (via Freeseve Broadband, IE,Outlook Express. I have tried all usual utilities, isolated and uninstalled a number of programs. It is possible (I can't remember whether this happened before) that this has only occured since installation of SP2. The only other major change has been renewal of Norton I/S licence but it still happens if this is disabled. I have plenty of resources Any ideas?
