BSOD l1c62x64.sys driver_irql_not_less_or_equal

[spyros7]

Hi all,

I've been having random BSODs pointing to l1c62x64.sys.
The crashes happen only during videocalls both with skype and viber.
After searching in other threads discussing the same BSOD, I uninstalled the ATHEROS driver and installed the newest version I could find on GIGAGYTE's webpage but the problem persists.
My m/b model is GA-Z77X-D3H.
I have attached the last minidump and a photo of the BSOD

Thanks in advance

The DMP you attached points to your video driver nvlddmkm.sys from Jan 18, 2013, not the Atheros L1C driver.

Quite old for a video driver, check NVidia for an update.

Thanks for the answer!
I have updated the video drivers.
So far no problems but I'll keep monitoring for some time..

Looks like the problem is not solved..
Just got a BSOD pointing again to l1c62x64.sys.
Minidump attached

The DMP still says the issue is the video driver, just the new one now.

Well, I just got another BSOD but this time it's a "REFERENCE_BY_POINTER" error.
I guess its the video card again but I attached the screenshot and the DMP just in case.
Looks like reinstalling windows is my only option..

If the issue is drivers then a reinstall normally changes nothing.

However that last DMP does not point to video, it points to the W7 kernal which basically means it is not clear of the case.
