Just like I said, this is a driver’s related problem of your computer and most of the times your Blue Screen Dump error will shows you the drivers name of your windows which is creating the problem.

Normally the drivers file name is listed beside the error name and looks like xxx.sys, or xyz.sys, or any file name who having .sys mentioned on its back.

There is 10% possibility that you computer can’t be abel to show any drivers name with the error message and just only showing you the “DRIVER_IRQL_NOT_LESS_OR_EQUAL” on the screen. Not showing the drivers name means that your computer or laptop isn’t actually able to identify that driver which one is corrupted and creating this problem.

In that case, you can still fix your PC but in this condition you’ll have to contribute little bit some extra effort of yours. So, to fix this error according to this condition, you’ll just need to follow all the instruction given in the article linked given below:

@Condition 2 – What To Do If Your BSOD Do Shows You Some Driver’s Name On The Error Message?

 photo stock-illustration-29911568-computer-trouble_zpsenkfs8xv.jpgAfter reading the content from above I think now you do know very well about, this is a driver related problem and you’ll have to remove or update that driver which one is creating this problem in order to fix your PC.

So now the main question is, How To Do That?

Mainly, the answer is in your Blue Screen Error because now you know what that file’s name which is creasing this mess and after finding that drivers file name, now it’s time to find that driver file on the drivers directory to get the full name or description of that particular drivers and here’s a great website listed down below which you can use to easily find your driver’s name by searching that .sys drivers file name in it.

Drivers Directory Link -> http://www.carrona.org/dvrref.php

In my case, my corrupted drivers name is “rtwlane.sys” and after searching it on carrona.com, I got the full description about my driver’s file which is creating the problem as you can see in the picture given below:

And after searching your drivers file name on the Carrona.com you will need to know what type drivers is yours, because there are two different types of driver are installed in your computer, and the first on is Windows based and the other second one is Hardware based as you can see the difference in the picture given below:

  1. Hardware Related Drivers – is the type of drivers what a hardware need to run properly and mostly these types of drivers listed with external driver source in the driver’s description.
  2. Windows Related Drivers – is the type of drivers what your windows need in order to work properly and all windows related drivers listed as “Windows update” in the source tab for description In Red Color.

Here’s The List Of Mostly Corrupted Drivers File Names –

  • athw8x.sys – Atheros Wireless LAN Driver
  • igdkmd64.sys – Intel Graphics driver
  • tcpip.sys – Microsoft TCP/IP Driver (networking related)
  • Netio.sys – Network I/O Subsystem
  • usbuhci.sys – UHCI USB Miniport Driver
  • iaStor.sys – Intel Storage drivers
  • rtwlane.sys – Realtek PCIE Wireless LAN PCI-E NIC driver

Both types of drivers can be the reason for this DRIVER_IRQL_NOT_LESS_OR_EQUAL BSOD Error and to make you PC’s fixed now you’ll just need to update that driver what you found by installing the latest version of that driver from the internet.

#Instructions To Download Drivers From The Internet.

In case, if your computer shows some of your windows drivers is corrupted then only update windows driver and if it shows some of your hardware’s drivers is corrupted then only update that hardware’s drivers.

So, Let’s See How To Update Drivers;

  • Windows Based Drivers (Source Windows Update– If you find your computer is having some problem related to the Windows Driver, then you can update your Windows Drivers by using a tool named called “Windows Update Utility”, which is actually provide by the Microsoft in all of their version of Windows, but download and installing a single Windows update won’t help your computer to fix this problem until you’ve download and install all the necessary updates given by the update center.
