After a windows update my HP laptop will not turn on at all.

[Cbarger81]

After several rounds of the black HP logo/screen it goes to a screen that said "my device ran into a problem and needs to restart".  I get the stop code  "Driver PCP WATCHDOG".  I have researched MANY ideas of how to fix this problem and none of the fixes have worked thus far.  This has happened since I bought the laptop a few years ago and should have returned it to the store, but usually after a few hard reboots it resolves.  This time I have NOT been so lucky.  Any ideas of how to fix this issue?

Hi @Cbarger81 

Welcome to the HP Support Community. Thanks for bringing this to our notice.

I see that you are facing blue screen-related issues on your system. Do not worry, we are here to fix it.

May I know from when are you facing this issue?

Did you make any hardware or software-related changes to it?

The BIOS can be corrupted during normal operation from a failed BIOS upgrade, or damage from a virus.   

Recover the BIOS using a key press combination.

Turn off the computer. Press and hold the Windows + b keys, and continue to press those keys while you press and hold the power button for 2 to 3 seconds. Release the power button, but continue pressing the Windows + b keys.

The power light remains on, and the screen remains blank for about 40 seconds before anything is displayed. You might hear a series of beeps (usually 8 beeps). Eventually, an HP BIOS Update screen is displayed and the BIOS update begins automatically.   

NOTE: If the HP BIOS Update screen is not displayed, press and release the power button, and then immediately press the Windows + b keys at the same time, repeatedly, until the computer beeps or opens the HP BIOS Update screen.

After the BIOS is recovered, a Continue Startup button is displayed and a timer counts down. Click the Continue Startup button to restart the computer immediately, or wait for the computer to restart automatically when the timer reaches zero.

If issue still persist then run diagnostics to rule out other hard drive issues

1. Start or restart the computer.
2. Press F2 repeatedly during start up to enter the HP PC Hardware Diagnostics UEFI utility.
3. Select Component Tests > Hard Drive > Quick Test.
4. Click Run Once.

Once the test completes, results are displayed on the screen.

If the drive passes all tests, continue to restore a computer back to the factory default, which will isolate whether it’s a software or hardware issue. 

The HP Cloud Recovery Tool allows you to download recovery software to a USB drive. You can use the downloaded recovery image file in order to install the Windows operating system. 

Click here for the HP Cloud Recovery Tool (Windows 10) link.

Hope this helps! Keep me posted.

This issue has happened every time the updates happened since we bought the laptop.  This last time was about 2 weeks ago and we have tried every thing possible to get it to boot up, nothing has worked thus far.  I started the process by trying the BIOS recovery which said the "system bios recovery failed. BIOS image file specified did not pass validation".  I checked the hard drive next which passed.  After the BIOS test it just returns to the HP logo screen with the moving circle of dots in the restart process but never makes it to the next screen.

Thanks for your response.

May I know if you have performed a cloud recovery or a complete Operating System Reinstallation on your system? If yes, can you please share the outcome with me?
