BSOD Driver_Not_Less_Or_Equal L1C63x64.sys


New Member
Yesterday, and this also happened a number of times before I reinstalled Windows 8.1, I got the BSOD stating Driver_Not_Less_Or_Equal L1C63x64.sys.

I use a wired internet connection and this seems to happen when I have my display extended between my laptop and my tv and I'm streaming video (I was trying to watch

I thought that maybe there is a problem with having my wireless activated at the same time (the first time this happened the wireless was also activated...though not connected), the second time it wasn't.

As I said, I recently re-installed Windows 8.1. I had no problems with this until just yesterday with this fresh install. I'm not sure what new program I installed could be causing this, though.

Here is the DM log. Thanks for any help. I never know where to start.

Hi packersfan & Welcome to the forums ^_^,

I have analysed your dump files and below has been provided an analysis of the same for informative purposes -

A driver has failed to complete a power IRP within a specific time.
Arg1: 0000000000000003, A device object has been blocking an Irp for too long a time
Arg2: ffffe000e8a8e7f0, Physical Device Object of the stack
Arg3: ffffd00078431960, nt!TRIAGE_9F_POWER on Win7 and higher, otherwise the Functional Device Object of the stack
Arg4: [COLOR=#FF0000][B][U]ffffe000e5ae4a20[/U][/B][/COLOR], The blocked IRP
So, a power Input/output Request packet was blocked for an extended time which caused the system to crash. Let's check the IRP and see if it reveals something or not -

The driver blamed in this dump file is the "rasl2tp.sys" (One of the networking drivers used for the proper functioning of Layer 2 Tunneling Protocol ) which is a part of the operating system and hence chance of it being at fault is really very less.

Below is a list of 3rd party drivers present on your system -

OpenVPN is known to cause problems on some systems. I would suggest you to completely remove this software from your system and see if the system remains stable or not.

Let me know how it goes ^_^
