How to Fix Windows Upgrade error 0xa0000400

If you suddenly encountered the PDC WATCHDOG TIMEOUT BSOD Blue Screen stop error with a bug check value of 0x0000014F, then it’s probably due to a system component that has failed to respond with the allocated period which prevents the system from exiting connected standby. This kind of Blue Screen error could be caused by both hardware and software components. To fix this Stop error, here are some possible fixes you can try that might help but before you proceed, make sure that you create a System Restore point first and boot your computer into Safe Mode with Networking.

Option 1 – Try to rollback, update or disable drivers

The next thing you can do to fix the PDC_WATCHDOG_TIMEOUT Stop error is to roll back, or update, or disable device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• After opening the Device Manager, look for the device driver named “IDE ATA/ATAPI controllers” and expand it.
• Then look for the SATA AHCI Controller entry and right-click on it. If you haven’t updated this driver in a while, select the “Update Driver” option. On the other hand, if you’ve just updated this driver, then select the Uninstall Device option.
• Next, follow the screen option to update or uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically if you have chosen to uninstall them.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 2 – Try to disconnect or disable newly installed hardware

In this option, you will have to disable or remove the hardware you’ve just installed recently since external devices could be the one that’s causing the Blue Screen of Death error to appear. To do that, just disconnect any external device that’s connected to your computer physically and then check if it fixes the PDC_WATCHDOG_TIMEOUT Blue Screen error.

Option 3 – Try running the Memory Diagnostic Tool

The Memory Diagnostic tool in windows can help resolve the PDC_WATCHDOG_TIMEOUT Blue Screen error by checking and automatically fixing any memory-based issues. To run it, refer to these steps:

• Tap the Win + R keys to open Run and type mdsched.exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Option 4 – Try to update the BIOS

Updating the BIOS can help you fix the PDC_WATCHDOG_TIMEOUT BSOD error but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version on your computer.
• Now restart your computer to apply the changes made.

Option 5 – Try running the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like PDC_WATCHDOG_TIMEOUT. It can be found in the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

https://www.edx.org/ edX has evolved from MITx, MIT’s free initiative to place some free academic lectures from its classrooms free into the world. Since it was rebranded into edX it started including other big university names like Berkeley, University of Texas System, Harvard, and many more. Since its infant days, edX has expanded and included many areas that it offers coursework from arts to science. Certificated today are mostly not free but course videos are, so if you care to learn and not wave certificates around this is a great place to do it.

Udemy

Udacity

https://www.udacity.com/ Udacity was also one of the earlier websites to offer free courses, in today’s world it still has free material but there is also paying one.

Academic Earth

https://academicearth.org/ Academic Earth has been built with one simple premise: Everyone deserves access to education.
