I have no programs opened but my cpu is running at 90+-%=.
I checked in task manager and it says that Explorer.exe is running at say amount.
like i said there are no programs running in the background or forground.
the cpu useage is just idling at around 90%.
I might not really get the situation. When you say that the CPU usage is idling at 90%, what do you mean? That the total load is 90% or the idle process is 90%?
Does Taskmgr show that it is explorer.exe that is consuming the CPU?
