BSOD IRQL_NOT_LESS_OR_EQUAL and random freezes

Hi Nisym.

A failure from the part of the display driver is found.

Code:

fffff880`0431d650  fffff880`055ed000Unable to load image \SystemRoot\system32\DRIVERS\atikmdag.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for atikmdag.sys
*** ERROR: Module load completed but symbols could not be loaded for atikmdag.sys
 atikmdag+0x50f000

And it is too old.

Code:

fffff880`050de000 fffff880`056f5000   atikmdag T (no symbols)           
    Loaded symbol image file: atikmdag.sys

HP does not have any feasible update to AMD HD Graphics driver for Pavilion DV7. I would suggest you to try AMD Driver Autodetect to find any feasible update for the Radeon HD 4650 GPU and apply it.

It is the prima facie issue but not necessarily the only issue. So let us know how the computer is running after the driver update.

Hi Nisym.

That is a laptop aging a few years. Apparently the installation is also aged. So outdated drivers etc plus laptops normal aging issues will be there.

You need not to be afraid. I just wanted you to not get frustrated if you see another issue emerges up after updating the display driver.

Edit: If there is a question why I said it a laptop despite of what is stated in the specs; I see the computer under analysis is a HP Pavilion dv7 Notebook PC, which is more reliable information to me than what is written in the specs.

After making it sure that you updated the display driver properly (not like what you did before ), wait for at lease one week. If it is all stable, then you might think about marking it as solved.

But if the issues bounce back again, unmark the thread and continue.

It will download the DM log collector. Right click on the application and run as administrator. It will generate a .zip file on your desktop. Upload the .zip.

Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

If it does not show any error, enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

   Information

Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

   Warning

Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

   Tip

• If you fail to get on the Desktop because of DV, Boot into Advanced Boot Options > Safe mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
• If you cannot boot in Safe mode too, do a System Restore to a point you made earlier.

Let us know the results, with the subsequent crash dumps, if any.
