1 hour "warm up" needed

[beejay]

My PC was working fine in the morning when a few emails were exchanged and PC was then shut down.

After booting up quickly in the afternoon in the normal time, the PC then needed an hour or so before it would run at normal speed. Before then it took AGES to open links or applications.

After the hour warm-up period all is normal. The same thing is happening again today. Can you help explain this, please?
