I have a fairly new laptop. It has a 1.8 ghz core duo processor, 1 gig of RAM. Recently, it seems that the processor is always running at 100% everytime I check the task manager, and programs are really slow to load. I have done several spyware scans, and they all came back saying I was clean. It seems that this all started when I ran iTunes and Nero at the same time. Any ideas on how I can fix this, short of a factory restore?

What processes are running at nearly 100%? In System Information you have a list of every process running and not just the .exe files that you see in the Task Manaager.

It changes. When I'm in Word, Word is using 99%. When I'm typing in MSN Messenger, its at 99%. When I'm not doing anything, it says system idle has 94%, yet the indicator bar stays solid green and things remain slow.

Perhaps Sysinternals free Process Explorer will reveal more information: http://www.microsoft...ssExplorer.mspx (Download link at bottom of page.) Like Taskmanager, if you choose CPU Time as one of your choices from View>Select Columns, and then click the column header, the processes will sort into order by how much time they have been accessing the processor. This may at least reveal whether there is a software process involved. Please also note the usage for "Interrupts." If high, it may be indicative of a hardware problem.

Thanks for all your help, but things were so bad, I did a format/reinstall last night, and now things are fine.
