Computer starts with the error “Stop 0x00000d1 DRIVER_IRQL_NOT_LESS_OR_EQUAL”.

Original Title: BSOD which says "Stop 0x00000d1 DRIVER_IRQL_NOT_LESS_OR_EQUAL",

My M14xR2 I purchased for my daughter keeps getting a error code and BSOD which says "Stop 0x00000d1 DRIVER_IRQL_NOT_LESS_OR_EQUAL", and I have started to get it every day. It also says it could be related to iastora.sys. I think this is a intel driver. Could anyone help me with this.

Hi Rodney,

Thank you for posting your question in Microsoft Community. We are glad to help you!

From your issue description, I understand that you are unable to work on the computer. Error is “Stop 0x00000d1 DRIVER_IRQL_NOT_LESS_OR_EQUAL”. Please correct me if I have misunderstood the issue.

Before we proceed with troubleshooting, I need to ask few questions.

Have you made any recent hardware or software changes to the computer prior to this issue?
How did you come to know that the cause of the issue is related to “iastora.sys – an Intel Driver”?
What is the current status of the computer? Are you able to login to desktop?

Note (1): If you are unable to login to desktop, try the methods below and check after each method:

Method 1: Check in Safe mode:

Step 1: Start your computer in “Safe mode”, to start the computer with minimal set of drivers and files.

Step 2: If the issue does not persist, then perform “Clean boot”, to disable third party startup programs.

Troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7.

Note: Once you are done with “clean boot”, please follow Step 3 from the above article to set the computer to normal startup.

Method 2: Start the computer in “Last Known Good Configuration mode”, to rolls back the most recent successful registry configuration.

Method 3: Upload the Memory dump file and provide the link of uploaded file:

Step 1: How to read the small memory dump files that Windows creates for debugging?

Step 2: Use the SkyDrive tool, to upload the files:
