Hi,
I have a serious problem with interrupts of the system using a lot of my CPU.
The problem started two days ago, that day I got a blue screen saying kernal security check failure.
I think my laptop was still doing fine after the reboot, but not long after I got some serious issues with my CPU.
It is using upto 70 percent of its power for a process called interrupts of the system
So I googled the problem got to a few websites, and one of them told me run latencymom to find out what the issue was.
That helped, because it gave me the following rapport:
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops.
One or more DPC routines that belong to a driver running in your system appear to be executing for too long.
At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results.
One problem may be related to power management, disable CPU throttling settings in Control Panel and Bios setup. Check for Bios Updates.
So I checked for the Interrupt Service Routine (ISR) and it turns out that the ISR of ntoskrnl.exe is through the roof and seems to be the cause of the problem.
So I tried fixing it, by first doing a clean boot, then disabling and reinstalling drivers, checking my memory disk for errors, and a few more things, but nothing seems to help.
So do you guys have any ideas on how to fix this issue?
Thanks in advance
