Hi iros9555,

Acpi.sys. “Slip of the keyboard” :-[, started to get dark, so I lit another candle. Acpi stands for “Automatic Configuration Power Interface” and is a driver which will attempt to throttle CPU usage when temperatures get to high (and other power management operations) - CPU 55 C HD1 36 C - if the sensor delivering this right to my Speedfan tool readings…Maybe I need the household fan to blow air into the case again?
But as to the solution I have chosen I thought more of a registry problem and acted accordingly. My heat sink is being serviced every few months.
