Hey guys.
I tried everything that I could find online and no luck, so I'll try to explain my problem with details, maybe, just maybe someone can help me.
First of all I have an ASUS G56JK laptop with Core i7 4710HQ, 12GB of RAM and Nvidia GTX 850m 2GB, 250 GB Samsung Evo 850 SSD and 1TB HDD as HDDCADDY, Bluetooth and Wireless are Qualcomm Atheros and SoundCard is Realtek.
Anywho, I'm an old Fast Insider and fortunately with this heavy use my laptop never encounter any problem that I couldn't solve.
I had Build version 14342.1000 and recently installed couple of developing tools like Visual Studio and Android Studio and Qt, couple of days later out of nowhere, windows started to showing BSOD almost every five minutes with error Win32kfull.sys has stopped. with the system restarting every couple of minutes I gave up trying to fix it and did a clean install of windows 10 Build 10586. (I mean complete clean install with formatting drive C and stuff) after I updated the drivers I noticed my Performance tab of Task Manager, it was (is) like this in idle time:
as you can see core 0 is almost on full load with every even core (core 2, 4, 6) working for no apparent reason. Yes I know it has 4 physical core and with hyper-threading it becomes 8 logical cores, whatever it is, it's not working properly.
but what process is using it? "System" and when I clicked the Open file location turns out it's the windows Kernel! In the 10586 build its name is System and compressed memory. with the help of ProcessExplorer I found out that the actual process is ACPI.sys that use the CPU on core 0.
I updated all drivers, downgraded them, used the OEM versions, other kind of apps. uninstalled them, no luck. in safe mode it's still there with a little less usage. I tried clean installing the windows that I downloaded from micosoft and right after the installation it was like that again.
So what do you think? what can cause this?
