Post upgrade to Windows 10 Pro I have been experiencing higher than usual system CPU usage (~10%), accompanied with system interrupts. I used process explorer (screenshot attached). It seems to be ACPI.sys.
All the drivers (that are available for Windows 10 ) are updated to their last versions, as well as the BIOS. Booted into safe mode - problem persists. SSD Firmware has been updated as well. I disabled non-critical devices one by one and the problem persists.
Laptop: ASUS N550JV; CPU - i7 4700HQ; 16GB RAM; NVIDIA GT750M; Samsung EVO 840 120GB (System Partition); Samsung EVO 840 500GB (additional non-windows stuff installed). Realtek LAN; Qualcomm Atheros WLAN.
I can provide the trace file from xperf as well, but it shows the processes as Unknown.
Any help appreciated! Thank you in advance.
