If you are bothered by the stop code attempted switch from DPC in Windows 10, you are not alone and many users have reported this switch blue screen. It is possible to fix the issue if you follow these methods offered by MiniTool Solution in this post.

Attempted Switch from DPC Windows 10/11

Blue screen of death (BSoD) errors from time to time occur on your Windows 10/11 computer. In our website, we have discussed many errors including Faulty Hardware Corrupted Page, the stop error 0x0000007B, System Service Exception, Atikmdag.sys BSoD error, Kmode Exception Not Handled, etc.

Today, we will show you another BSoD error – attempted switch from DPC Windows 10 crash. It usually happens during the boot-up phase of your Windows operating system. On the computer screen, you can see the error message “Your PC ran into a problem and needs to restart…Stop code: ATTEMPTED_SWITCH_FROM_DPC”.

In addition, this blue screen of death error also happens in Windows 8 and 7. And it is also known as STOP 0x100000B8.

The error is triggered by a DPC (short for delayed procedure call) routine that attempted to perform an illegal operation. When a hung condition is detected by the kernel, the DPC gets triggered and makes a call to interrupt or terminate the software. This means the DPC routine executes a yield, attach process or a wait operation.

The causes behind the attempted switch from DPC error include faulty memory, virus or malware attack, incompatible software, a damaged device driver, a hardware driver conflicting with another, etc.

As annoying as it seems, it’s possible to fix the issue. Here are some methods that you can try to fix the stop code blue screen error.

Attempted Switch from DPC Windows 10/11 Fix

Sometimes the switch blue screen can be resolved after you reboot your computer but it also appears from now and then. In this case, you can perform the following ways to fix it. If the PC fails to boot, Safe Mode or WinRE is required and we will show you much information later.

Fix 1: Scan the Computer Memory to Check for Problems

One possible reason for Windows 11/Windows 10 ATTEMPTED_SWITCH_FROM_DPC is damaged computer memory or RAM. To make sure that you find out the exact cause, you can run a memory check as described below.

Tip: In our previous post – How to Tell If RAM Is Bad? 8 Bad RAM Symptoms Are for You, we mentioned one sign of bad RAM is the blue screen of death.

Step 1: In Windows 10/11, go to Control Panel, click Administrative Tools and choose Windows Memory Diagnostic. Alternatively, you can type memory diagnostic to the search bar and click this tool to open.

Step 2: Two options are offered and here we choose the first one – Restart now and check for problems (recommended). Note that you have saved all your work before you do.

Step 3: Your computer will restart and you can see the memory diagnostic tool is performing the check operation.

The whole process will take some time. Once it is completed, Windows will automatically reboot and return to the desktop. The results will show up after logging on to Windows.

Also, you can check the results manually by following these steps:

Step 1: Press Win + R on your keyboard, type eventvwr.msc to the text box of the Run window and click OK.

Step 2: On the left pane, go to Windows Logs > System and click Find on the right pane.

Step 3: If you see some errors, you have bad RAM and you need to replace it. If nothing is seen here, it means the memory is good and you can try other methods to fix the attempted switch from DPC BSoD issue.

Fix 2: Update Device Drivers

Faulty or incompatible device drivers could trigger the blue screen error. Besides, the error could be caused by a conflict between one or more drivers. To get rid of the stop code ATTEMPTED_SWITCH_FROM_DPC in Windows 10/11, you should make sure all your devices have the correct drivers and update those old drivers.

To do this work, there are two ways you can try. The first method is using a professional driver update tool like Driver Easy, Driver Booster, etc. to automatically detect the correct drivers, download and install the latest versions on your computer. This way is less time-consuming since you won’t install drivers for your devices one by one.

Alternatively, you can go to the website of all the hardware devices installed on your computer, download and install the up-to-date drivers. This is fairly time-consuming, thus, it is better to use the first way.

Fix 3: Run a Virus or Malware Scan

Another common reason for attempted switch from DPC Windows 10/11 is a virus infection or malware attack. If the computer is impacted, there may be some corrupted important Windows system files, leading to the blue screen issue.

In Windows 10/11, you can open Windows Defender to run a full system scan.

Step 1: Open Settings and choose Update & Security.

Step 2: Go to Windows Defender > Open Windows Defender Security Center.

Step 3: Click Virus & threat protection and Advanced scan.

Step 4: Choose Full scan and click the Scan now button. Alternatively, you can choose Windows Defender Offline scan to remove some malicious software.
