My PC is boot looping with stopcode SYSTEM THREAD EXCEPTION NOT HANDLED. Issue with soundcard drivers. Any ideas?

Question

So i was having issues with my sound on my laptop, so i decided toremove the drivers and reinstall them.

Unfortunatly, something went wrong with the reinstall and i keep getting Blue screen of death every tome i trie to boot.  Nothing seems to stop this boot loop.

The stopcode is SYSTEM THREAD EXCEPTION NOT HANDLED . And rtkvhd6.sys is what is going wrong. (I know this is my Realtek driver).

it will not let me access safe mode. I have lots of files and programmes i do not want to lose, so what can i do?

Hi RobHarris3

I am Vijay, an Independent Advisor. I am here to work with you on this problem. If safe mode through USB below doesn't work, then clean install (point D) will be only option.

A. Try to boot into safe mode

Power ON your computer and as Windows / manufacturer's Logo appears, Power OFF - Repeat 3 times

Now your computer will go into Advanced Recovery Environment

Advanced Options > Troubleshoot > Advanced Options > Startup Settings > Restart

Press 4 or F4 to enable Safe Mode (5 or F5 to enable Safe Mode with Networking)

Log in once Windows starts in safe mode

See whether you able to login. If yes, come out of this and start normally.

If you are not able to boot like above, You will need to boot through a Bootable USB drive. You will need to create this on another computer which is working - https://www.tenforums.com/tutorials/2376-create...

B. Another option when you are in Advanced Options in previous step is to choose (Note - You won't lose any files in this step)

1. System Restore - This will restore your system to a point when things were working fine.

OR

2. Startup Repair - Startup Repair upgrade fixes all Windows errors and retains all files, applications and settings.

C. Penultimate option could be Reset this PC.

In Step A > Troubleshoot > Reset this PC - Keep my files and Remove everything. Choose this carefully as most likely you would like to keep your files.

All apps will be removed and windows will be reinstalled.

D. Last option could be a clean Install. This is the best method to perform a clean install of Windows 10. (If you want to rescue your files, there is a section Rescue Files when Windows Won't Start)

If the driver named on the blue screen is a Realtek audio driver try entering the BIOS and disable the onboard audio.

Answer 3

Hi Rob,

Start your PC, just as Windows attempts to load (spinning dots), press and hold Power Button for 5 - 10 seconds to perform a Hard Shut Down

Do this twice

On the third start Windows will boot into the Recovery Environment and from there you can access System Repair, Safe Mode, Command Prompt . . . etc.

Please try each option one at a time, then see of Windows will boot correctly, please note: all options will keep your files and applications, except the reset option, that will only keep your files . . .

Go to Troubleshoot - Advanced Option - Startup Repair

See if Windows startup can repair itself

Go to Troubleshoot - Advanced Option - System Restore

Check to see if you have a restore point you can go back to

If you do not have a Restore Point, go to Troubleshoot - Advanced Option - Startup Settings and click Restart

Upon restart, press 4 to enter Safe Mode

Once in Safe Mode, backup your data if you do not already have a backup

Open Device Manager and check to make sure all your Drivers are up to date

Reboot to see if Windows will start Normally

If the above fails, go to Troubleshoot - Advanced Options - Reset this PC

Choose to keep your files and apps, just your files or to keep nothing

Then start the Reset
