I need help with my Windows 7 64-bit, Asus K52F laptop. After unintstalling ZoneAlarm and restarting my computer, the computer boots up with a BSOD: driver_irql_not_less_or_equal.

Afterwards as i tried booting the computer in saf-emode. I get the error message A windows unexpected shutdown:

Problem Signature

probrem event name : bluescreen os version: 6.1.7601. Locale ID: 4105

Aditional information about the problem: BCCODE: d1 BCP1: 0000000000000010 BCP2: 0000000000000002 BCP3: 0000000000000000 BCP4: FFFFF880014E8566 OS Version: 6_1_7601 Service Pack: 1_0 Product: 246_1

Files that would help describe the problem: c:\windows\minidump\120612-13946-01.dmp c:\users(name)\appdata\local\temp\wer-25818-0.sysdata.xml

ALSO: i just tried recently, safe mode works, safe mode with command propt works, but safe mode with networking does not work. Is there a message from this?

  • upload the file c:\windows\minidump\120612-13946-01.dmp so that we can look at it with WinDbg Dec 7, 2012 at 9:08

Open these "files that would help" and look whats in there.

driver_irql_not_less_or_equal means, that a driver is missing or corrupted, what means, that you will have to reinstall it from the safe mode.

Only by looking into the files that could help you can see, what driver is missing.

  • I also cannot open minidump so that would be useless. and cannot find the appdata file Dec 7, 2012 at 23:38
  • @user178648 - There are programs that can do this. Since your posting this, you must have some sort of access, you will need to get the file and open it. We can't help you otherwise.

  • I'm not sure, if in Safe Mode you can see every file. If not, you'll first have to "unlock" them. In the explorer windows, go to Tools > Folder Options > View > Untick "Hide system operation files" and tick "Show hidden files and folders" Dec 8, 2012 at 12:14
