Every so often my computer semi freezes, ie it goes into 'I'm doing something' mode, and the hourglass comes up beside the cursor. Sometimes it comes back after a bit, other times it just freezes, and I have to do a warm reboot. When I press control/alt/delete taskmanager shows 65/66 processes running and up to 46% processor usage. I've looked at the list of processes and most of them mean bugger all to me. I feel as though I have a worm or something but my AV {Norton} doesn't detect anything. I am running Windows XP Home Edition. HELP
