Does disabling SEP resolve it?

NO

So has anything changed recently? Have they always been like this?

no change.

the proces SYSTEM is the cause of HD led always on

Hi,

After disabling SEP if issue is reocurring then need to check the SQL db maintenance schedule, logs.

Check the eventvwr logs as well.

i hope to have found the solution ..... sep is innocent ...
did this change:

in advanced settings - performance options - advanced - processor planning set to programs instead of background services

at the moment, server never blocked
