After computer has been on for several hours, when I open Task Manager (Ctrl Alt Del) most of the programs show higher than normal usage. (15-60 meg).It is usually connected to the internet via DSL, no router.Performance is not as good, but stil isnt super slow (not a big problem yet). After restarting, the usage is low for all programs and there is no performance issue.What can cause this? Anti-virus scans good. Clean up with CLeaner does not affect the results.1 person needs an answerI do too
