Get another screenshot as well of the CPU usage / System Idle - this time organize the CPU usage column so we see what .exe is taking the CPU - I spotted a scroll bar - so try moving it around til we find the executable taking up the processing time.
is adaware up to date?[/I]
I been pushing the system harder than what obtained the earlier observations but haven't been able to get the System Idle Process to "take over" like it did earlier.
Working on implementing your suggestions...
