I have a Packard Bell 5095. When I switch on my computer it runs for about ten minutes or more slowing the computer and I have found that when I press Ctrl/Alt/Del the windows task manager comes up and the performance CPU history is going and the cpu shows varying up to 60%. I don't know what this means but assume this is slowing the computer down. Have defrag/check disc no improvement. Any suggestions would be greatly appreciated.
