Windows 7: Nasty BSOD - ntoskernel.exe - IRQL_NOT_LESS_OR_EQUAL

Nasty BSOD - ntoskernel.exe - IRQL_NOT_LESS_OR_EQUAL

Hi there,

Just getting stung with a new BSOD problem out of the blue, only recent changes are a new hard drive which isn't the main C: drive and it's reporting as fine, seems fine.

Suspect the issue began when I installed the 2012 version of Anti Vir, that is when things really got strange.

Attached a couple of BSOD reports. Gutted because I haven't had any for months and thought everything was fine.

Cheers

2012 Anti-vir?

These were caused by a memory exception (probably your vodaphone driver). Please run these two tests to verify your memory and find which driver is causing the problem.


1-Memtest.

*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool

*Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

RAM - Test with Memtest86+



2-Driver verifier

Quote:
I'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Windows 7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

I ran Intel Burn Test for 50 passes overnight, passed fine. Memtest86 is fine.

Interesting about that vodafone driver, I don't need it anymore. I thought it was all uninstalled, how can I get rid of it?

Anti Vir 2012 seemed to be the catalyst for these problems. It's my anti virus, it just got "upgraded" to a 2012 edition and noticed strange things after that.

I've found the Vodafone drivers under "view hidden devices" in device manager and deleted them.
