Inexplicably slow computer, but not overloaded

[andyfarang]

I have Lenovo T530. This is the situation:

Opening folder in new window: computer freez 8 seconds
Opening subfolder: freez 5 seconds
Opening for example email client: freez 15 seconds
Navigating between new emails: each click = 5 seconds freez
Trying to write new email in new window: freez 10 seconds

You get the idea... .


But what I don't understand - When I open TaskManager, CPU is at 0% and memory at 800MB (of 4GB).

So what is the problem? My computer isn't overloaded. Why is it so slow?
