CPU 0 100% usage and overheating due to Interrupts
Hello, thi is my first post in the forum.
I have a Asus k53sc notebook, and during the past week i have noticed a strange behavior: the CPU 0 is always between 90% and 100% of using, bringing the temperature to 95-100 °C.
The issue seems random, it can show between 10 minutes and 3 hours from the boot.
I scanned with various utilities for virus or rootkit, the PC seems clean.
I did a fresh install of win7, without installing any driver and the problem stills here.
Changing power management to Balanced or Energy Saving did'nt slow down the first CPU, but helps keeping the temperature between 70 and 80°C
Process Explorer did'nt show any process eating up CPU usage, but every time the problem is there, i see Interrupts bild up to 9-12% CPU usage, wich seemes compatible with the first CPU full usage.
Latency Mon shows that the driver with highest execution are ndis.sys, ACPI.sys or tcpip.sys.
Disabling the network adapters did'nt help, neither disabling networks adapter power management.
Removing the battery did'nt helps.
Can you point me to the right solution?
Thank you!
Simone
