Existe um uso excessivo repentino do CPU e não consigo identificar a origem?
Hi everyone, I hope someone here can help me find the right solution since I'm getting really confused about this issue.
According to the title, when my PC is idle or not in use, the temperature indicator on my NZXT AIO jumps from 34°C to 39-42°C, which always happens because of a system process—specifically the ntoskrnl.exe application.
I've been checking numerous posts and websites, trying different fixes, but nothing seems to work:
1. I opened Device Manager and attempted to update drivers for every component, but none were installed since everything was already up-to-date.
2. Using Bitdefender performed a full custom scan of my drives with no issues or malware detected.
3. From the command prompt, I ran commands like scannow and restore health, but nothing was found corrupted or fixable.
4. I created a registry file with specific settings to address memory problems, which temporarily improved things for a few days before the temperature spiked again, causing the system process to run at 20% of my CPU.
5. I updated the BIOS and ran a memtest, which found no issues in the DDR memory.
I also tried reinstalling the graphics drivers and performing a clean boot (after seeing it on some websites).
Any suggestions on what I should do next? I’m really worried because this issue seems linked to the ntoskrnl app becoming corrupted, especially after my AIO pump stopped working a month ago.
It’s driving me crazy, and I truly believe there’s a major problem with my PC.
When sharing troubleshooting threads, it's important to provide detailed system specifications. List them clearly as requested:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
Include the age of the PSU along with its make and model.
Updated BIOS:
What BIOS version are you using for your motherboard?
Run a clean boot to check for issues.
Did you reinstall the operating system or perform a system reboot?
Aaah duuuh yes:
Intel I7-11700KF
RTX 3080 EVGA FTW 3 ULTRA
2X32 GSkill Trident Royal Elite RAM @4266mhz (both in the same package)
SSD: XPG M.2 1gb / D. Drive: SSD Adata (exact specs not remembered)
Asus Prime B560M-A AC
Cougar 850+ Gold PSU
Bios: updated from 1601 to 2001 (latest)
Starting a clean boot means launching Windows with the fewest processes and drivers

Uncertain about what to search for, but I should focus on conflicting software (maybe)
It's a bit complex, but if you're looking to uncover the specific processes running in the background with ntoskrnl.exe, consider using Process Explorer from Sysinternals.

Additionally, Process Monitor is available.

Whether these tools assist you in finding a solution depends on other factors.
If you have an extra SSD, even a 120GB 2.5" SATA drive, try reinstalling Windows.
I can set up a basic Windows installation in under an hour—sufficient for troubleshooting.
Thanks man, I think if I can identify the precise process generating the Ntoskrnl issue, I should be directed somewhere at least. Reinstalling Windows feels like my best option in an emergency since I'd need to reinstall everything on my C drive irrc... sigh I digress. Thanks man
I just arrived here to express my concerns about this issue. Could you all handle this properly?
I often notice that the 'ntoskrnl' process appears high on the CPU usage list. Even when no applications are running, it still uses around 2% of the CPU. I believe this is why Windows laptops perform much worse than Macs in terms of battery life. The main issue isn't the hardware or CPU—it's the operating system itself!
I'm not certain how many Microsoft developers are reading this forum, but Ntoskrnl plays a key role in Microsoft Services, which explains why it uses significant clock cycles during background operations. Maybe I should consider using an Apple Mac laptop for better battery life, though they usually exceed my budget.
I postponed a clean Windows installation as a temporary solution on a struggling PC for about two years, constantly restoring an earlier Macrium Reflect image to the damaged drive. Over time, the 10Gigabit network controller issue kept recurring, causing me to lose internet access repeatedly. Regardless of the NIC firmware or drivers I tried, the card would still fail.
Eventually, I followed the recommended steps sooner and started fresh. The process took just over half an hour for installation, another half hour to adjust settings, and six hours to set up my preferred applications. Now I have a reliable system and no longer spend time fixing problems on a Windows 10 version that's been running for four years.
