Make sure your hosts file is not too large to avoid this usage. Here, the CPU usage comes from scanning the host file (netbt.sys!DelayedScanLmHostFile)

So update the driver if you see it in the stack. This is the qualcomm atheros AR8171/8175 PCI-E gigabit Ethernet driver. In this case, the CPU usage is caused by the driver L1C62圆4.sys Disable some devices/drivers until you see one which causes it. So a driver is using SpinLocks very heavily. In this demo, the CPU usage ntoskrnl.exe!KeAcquireSpinLockRaiseToDpc and ntoskrnl.exe!KeReleaseSpinLock.

In this case, a small amount of SYSTEM usage comes from the Acronis driver tdrpm251.sys: In this demo, the function usbhub.sys!UsbhPortRecycle causes the CPU usage:Ĭhanging USB2.0 ports to 1.1 speed or connecting USB drives to other USB 2.0 ports helped for some users.

So contact your IT for how to solve Citrix issues. In the following demo, a citrix driver is involved: Search for a driver update if you see this. In this demo, the CPU usage is caused by the WIFI card driver athrx.sys In this case, the CPU usage seems to come from the Data Deduplication Feature ( dedup.sys!DdpPostCreate) of Windows Server: In Windows 10, the task is called RunFullMemoryDiagnostics under Microsoft > Windows > MemoryDiagnostic > RunFullMemoryDiagnostic. You can use Task Scheduler to disable the idle task. This usage is triggered via the idle maintenance task of Windows 8.1/10. The CPU usage comes from the Kernel to test memory for issues (memtest). When you see those ntoskrnl.exe!RtlpGenericRandomPatternWorker, ntoskrnl.exe!RtlpTestMemoryRandomUp calls So if you see this and use Chrome, turn hardware acceleration in Chrome off.

There is no real way to detect which process causes it, but I know that Chrome can cause it if you have hardware acceleration enabled in Chrome. This means the function of the kernel which zeros the memory before it can be used again causes the high CPU usage: When you see ntoskrnl.exe!MiZeroWorkerPages as cause, it is trickier. In the following example, the CPU usage is casued by the broadcom network driver bcmwl664.sys This demo shows that Bitdefender driver ignis.sys In this example, the CPU usage comes from the file rtsuvc.sys which seems to be the Realtek UVC webcam Driver

#Brkrprcs64.exe high cpu usage serial#

In this demo, the driver iai2ce.sys (Intel Serial IO GPIO Controller driver) causes it: This also hurts performance a lot and causes high SYSTEM usage. When you see calls like ntoskrnl.exe! ViKeTrimWorkerThreadRoutine, ntoskrnl.exe!Mm VerifierTrimMemory, ntoskrnl.exe! VerifierKeLeaveCriticalRegion, this means you have Driver Verifier enabled. In the following demo, the CPU usage comes from the Realtek NIC driver: In this demo, the CPU usage comes from the nVIDIA driver. Inside WPA, load the debug symbols and expand Stack of the SYSTEM process. Now analyze the generated ETL file with the Windows Performance Analyzer by dragging and dropping the CPU Usage (sampled) graph to the analysis pane and ordering the columns like you see in the picture: Now run WPRUI.exe, select First Level, under Resource select CPU usage and click on start. If you still use Windows 7, use the SDK/WPT with Build 15086. The Windows 10 WPT can be used on Windows 8/Server 2012, Windows 8.1/Server 2012R2 and Windows 10/Server 2016.

#Brkrprcs64.exe high cpu usage install#

To capture the data, install the Windows Performance Toolkit, which is part of the Windows SDK. To diagnose the CPU usage issues, you should use Event Tracing for Windows (ETW) to capture CPU Sampling data / Profile. This is why diagnosing the specific culprit can require a bit of detective work as described below.

#Brkrprcs64.exe high cpu usage drivers#

The System process loads (or hosts) multiple hardware drivers from different vendors that require higher level of memory access. High CPU usage by the 'System' process can often be caused by a hardware driver issue (bug, old version, incompatility etc). From the system start, it is using like 5% of the CPU only, but after 2-4 hours of working it is growing up and reaching 40-60% of the CPU usage. Sometimes CPU usage is reaching 90%, but the average usage is like 40-65%.Īs the user below posted a great answer, I have noticed that the process that is eating the most CPU in the system is called Arthurx.sys, simple google tells that it's a TPLink driver (an wifi adapter, I have bought like 2 weeks ago!) drivers has been installed from the Windows MSDN, but also tried to install the drivers from the attached CD, but it doesn't help. You can see the problem itself and running processes in the screenshot below: I have noticed that from some time my system is freezing and its probably caused by the high CPU usage which is caused by the system process.Īll applications I'm running is the Skype, TeamSpeak and Chrome so it definitely shouldnt eat that amount of CPU.
