Windows 7: Irql_not_less_or_equal

Windows 7 Professional 32bit SP1
Irql_not_less_or_equal [Solved]

Hi Guys.

I know there are loads of posts about this IRQL_NOT_LESS_OR_EQUAL problem. I've looked at

Blue Screen of Death (BSOD) Posting Instructions

I've downloaded and run DM Log Collector which saved txt files in SFdebugFiles folder. Even though the smallest file is 2kb the drivers.txt is 67kb but there is nothing in it.

I can upload any of the 6 txt files you want to see + 7 dmp files?

Its a Samsung NP350E7C-A04UK Laptop
Intel Pentium B970 processor (2MB L3 Cache) Intel HM70
2.3GHz processor speed
6GB DDR3 System Memory at 1333MHz (4GB x 1 + 2GB x 1) 2 SODIMM

I've run Windows Memory Diagnostic. I've looked at the event viewer at the results. The laptop won't keep running long enough to check things out.

I have a memory checker on CD but the original DVD drive doesn't open properly I have an external USB DVD drive which I use to install software.

This laptop has run I won't say perfectly for a few years as there are annoying bugs in Windows 7 but its generally pretty good.

Any suggestions would be appreciated.

Hi Keith,
please upload ALL the logs.

you could also try booting into Safe mode, then run
sfc /scannow (note the space)
chkdsk /r

Ok Roy I've added to files.

I will try sfc /scannow

As for chkdsk /r this process is a pain in the backside as it takes bleeding hours to do. I even left it running all night and it eventually finished in the morning.

Thanks Roy.

Ok I did run sfc /scannow but it still gets the BSOD after a few minutes. I open Computer and right-click on the hard drive for properties. I clicked check drive for errors. I did a restart and chkdsk started. I went out of the room for a minute when I can back Windows had started again.

I had to run cmd prompt and type in chkdsk /r /f /x, its said it would schedule on the next startup (I had to do that last time I did a chkdsk. I restarted and chkdsk started. It gets through stage 1, 2, 3 pretty quick. Stage 4 takes for ever it gets to 18% and doesn't go up even though the file count goes up slowly. I left it running and Windows restarted.

I looked at C:\Windows\Logs\CBS\CBS.log to see the results of sfc /scannow the file is quite bit at 2,516kb. Without deciphering what each line of code means that would take hours. I can post this file if its needed?

I looked for the chkdsk log file.

Please wait while your computer restarts.

I only see 28 KB in bad sectors.

As I've said I ran Windows Memory Diagnostic. After it restarted I check the errors found it said:

Hi Kieth,
Thats not good news.
Those BAD sectors will only grow, it found and added 7 more just from this run, and depending whats on them your system WILL get worse.

Suggest you make an image back-up NOW, buy a SSD.
