Hi! @dchill32, Thanks for stopping by HP forums!

I understand you are getting L1C63x64.sys error on your PC.

Don't worry I'll try to help you out.

Did you make any software or hardware changes on your PC?

Try running system diagnostics on your PC and let me know the results.

Refer this article to know how to run system diagnostics on your PC.

Please try the steps recommended below.

1.    Search for Settings from the taskbar and select it from the search results.
2.    Select Update & security and click on Recovery.
3.    Go to Advanced startup and select Restart now.
4.    After your PC restarts to the Choose an option screen, select Troubleshoot >  Advanced options > Startup Settings >Restart.
5.    After your PC restarts, select a startup setting as Safe Mode with Networking by pressing the corresponding number.
If the issue does not persist in Safe Mode with Networking, then perform a Clean Boot to check if any third party application is causing the issue, as Clean Boot helps in eliminating software conflicts.
 

Let me know if this works!

Have a great day ahead! 🙂
