Driver IRQL not less or equal L1C63x64.sys

Hello,

Since I've upgraded (last week), this issue happened at least 10 times and I couldn't find any solution about this issue. I suspect it might be related to a driver, but I couldn't put the finger on which one.

From the driver name "L1C63x64.sys", where should I start looking? Or what should I do to try to debug this?

Maybe this might help:

UPDATE: I tried to update my ethernet driver (and disable the juniper one). Seems it didn't fix the issue. This is my driver: Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.30). I feel like this is the issue, but I can't pinpoint the exact problem?

Hello,

 

Welcome to Microsoft Community. I appreciate your efforts towards resolving the issue. I will certainly help you with the issue that you are facing.

This issue arises due to a driver failure, conflict or incompatible driver on the system.

Try the following methods and diagnose this issue further.

Method 1: Safe Mode

Step 1:

To start Windows 10 in safe mode:

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 persists 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.

Step 2

Put the computer in Clean Boot and check if it helps.

By setting your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue.

Hello,

Finally, the problem still persists even though I tried everything in this reply.

I am going to downgrade to Windows 7, unless there's something else you suggest me?

Thanks!

I had the same problem and it turned out to be a conflict with Bullguard antivirus software. I have uninstalled this software and I had no more BSD for few hours. Hope it helps,

Hey,

I had issues with a third-party software (and drivers) from Juniper. I remember I uninstalled and removed everything related to those drivers on my computer and it helped a lot.

But in the end, I still downgraded to Windows 7 (for other unrelated issues).

But thanks for the answe!
