Deferred Procedure Calls And Interrupt Service Routines High CPU

Recently I have noticed higher than normal CPU usage from my laptop which I know will reduce battery life, cause higher temperatures and slow the computers performance.The task manager did not tell me too much so I decided to have a look in the Resource Manager.Sure enough under the CPU tab of the Resource Manager there is a process called System Interrupts that has a description of "Deferred Procedure Calls and Interrupt Service Routines" with a average CPU usage of about 30%.I did notice that when I first turn my laptop on and boot in to Windows that this process uses about 1 - 5 % CPU usage and my temperatures stay at about 28 - 32 degrees Celsius.Usually after some time of using the laptop I notice this temprature rises to about 48 - 54 degrees Celsius and when I check the process it is using around 30% CPU usage, usually to resolve this I restart my laptop and everything goes back to normal and the process is back down to 1 - 5 % CPU usage.I done a little research online and found that clean boot of Windows may solve the problem, I did this then re-installed all the required drivers from my system manufacturer, installed Avast Antivirus Pro then done a Windows Update.
