laptop CPU0 core at 100% utilization

[Xerocast]

Good day.

 

I own a ASUS FX550JX laptop. The i5-4200h inside is a dual core with hyper-threading. Ever since reinstalling windows 10 on my laptop i have had a strange problem. From startup the OS uses 100% of my CPU's core 0. I have un-installed all the programs i myself installed and disabled numerous services in an effort to see what is causing the problem. in addition i have also updated all my drivers and even downloaded the newest drivers along with each and every driver (even though i do not need most of them) that the manufacturer supplies you with. A clean install has also been done yet still no results. I have scoured the Internet for a solution but have not gotten anything yet.  

 

I apologize if there is a similar post out there. I have tried a massive list of things i can do to solve this issue. 

 

Specs of the laptop:

Intel Core i5-4200h (Dual core 2.6ghz with hyper-threading boosts up to 3.4ghz)

GTX950M 2GB DDR3

8GB DDR3-1333mhz RAM

1TB Seagate HDD

250GB Samsung Evo 750 SSD (installed into CD-Rom slot)

15.6" 1080p 60hz LED display

 

Attached i will leave you with a photo of the task manager. See the CPU's core 0 being used 100%. I have observed the task manager for several hours but it never stops. I have tried multiple different anti-viruses along with malware detectors but have not found a single virus. I mainly use the laptop for light gaming and studies. I have uninstalled my virtual machine software as well because of the amount of processes even when not open that are running. yet no changes. The laptop previously had windows 8.1 on it when i bought it. i installed windows 10 (it had a windows 10 on it previously which had no such problem and is the exact same version as i am running now). This specific version of windows 10 is also being run on my desktop which has a i5-3570k clocked to 4.5ghz with 8gb of ram and a GTX980 and it runs perfectly fine without any such riff raff as on the notebook. 

 

My main concern is the heat. the laptop idles at 60-70" C and the battery life is now very poor. The main processes that are using the CPU is the System and System Interrupts Processes. 

 

Thank you in advance for anyone willing to lend a helping hand.

now that's concerning...

 

what are your startup programs?

 

deeply embedded root-kit maybe?

I have seen this happen to my machine under windows 7. Core 0 was used really heavily while the other cores sat around doing nothing. While restarting did it for me I am guessing you already tried that. I kinda suggest to just clean install windows 10 again

I have tried a clean install multiple times now. Maybe i should try a different OS but i really would like to stay with windows 10. I have attached multiple photos of the processes involved and used along with the startup applications.

a little update. I installed windows 7 in an effort to check if its windows 10 that is the problem. In windows 7 the CPU is constantly used at 30% but this time across the 4 threads instead of just core0. I have formatted back to windows 10 again and installed each and every last driver i could find. Now the CPU is being used the same as in windows 7 up until my 5th restart and it raping core0 again. It seems that the culprit is The System Interrupts process.

 

What i don't understand is that throughout all the process applications i have tested the system interrupts only use between 10-15% of my CPU at idle. But task manager reports a total of 30% usage? i take it all of the other applications that require some processing power that are close to 0 is at fault for the rest of the CPU? or can it be something else? i tried taking out my main HDD and formatting the SSD  with a clean partition. I've scanned both hard drives with Malware Bytes, Avast, Avira, Bitdefender and Windows 10's own defender and malware application but the search came up empty. 

 

It's really irritating to barely use the laptop and have the clock speed boost and the laptop to start heating up.

Another update as i was playing around with the power settings after my re-format back to windows 10 i noticed CPU usage drops along with the MHZ all the way down to 8% and 0.7ghz. The heat is almost non-existent now and laptop's battery already has an extended usage. I am not sure what the problem exactly is, Performance mode clocks CPU to 3.0GHZ and sometimes up to 3.4GHZ and uses 30% constantly. Balanced mode uses around 20% of the CPU and clocks down to 1.76GHZ where as performance mode can go as low as 6% and 0.74GHZ. I replicated the power saving option and customized it to my liking but the first profile i made did not work where as the second one i made did. I still want that processor idling at around 0-3% but i guess the 6-10% isn't half bad. Hopes this helps anyone that comes across the problem.

Hi! I have exactly same with your problem. I tried reinstall windows 10 many times but has no chance, when I install windows 8, problem is gone, but when update to 10 its happen. After many times trying, I guess problem is in the power option, but dont know how to fix it. If you have any solution, please help me, Thanks.

P/s: In Windows 8, at Balanced and Power Saver, all cpu work fine, but if change to High Performance, CPU 0 will always 90-100%.
In Windows 10, Balanced, PS, HP is same, CPU 0 always high if I choose 100% at "Maximum Processor State"

It's prolly some of the process forces the "tick" at Core 0 rather than it being distributed to other cores. Check the apps that are using the core a lot (System process is just a general usage, you need to go deeper. The Process Monitor by sysinternals is a good start)

I'll try but I think it's not about the process forces ticked at "Core0". Because my upload picture is when I just fresh setup windows 10. I cleaned my ssd. And I checked all apps checked from Core 0 to core 7.
Thanks btw, I thought no one can see this topic
