I have a toshiba satelite laptop with 1.6 celeron. the cpu usagea goes all the way to 100% as soon as I start the computer. when I go into the task manager, processes, the system idle process stays in up in the 90% cpu usage consuming almos all the memory. I have scanned the computer with mcafee antivirus and found no viruses. also I ran spybot and cleared all the spyware, but nothing seems to work. I really dont want to format my computer. any comments will be appreciated.
