BSOD - Driver IRQL_Not_Less_Than_Or_Equal(Included SF Diagnostic File)

Hi all,

I've been getting the "Driver IRQL_Not_Less_Than_Or_Equal" error recently and I had no idea why.

I only get this error when playing games like Battlefield 3, Rage or other graphic intensive games.

I never install any hardware recently and except for a Samsung F3 1TB Hard disk that i brought recently.

Please help and advise me on what to do, thanks alot

P.S. Let me know if the zip file is contains all the vital information.

Your reports have given many causes. One that appeared sevearl times is Athurx.sys.
Productname:Driver for Atheros CB42/CB43/MB42/MB43 Network Adapter Description:Atheros Extensible Wireless LAN device driver Company:Atheros Communications, Inc. File size:Various

Update driver and continue to use computer. If problem continues, I would go for a driver verifier test. This will give the true cause. If it is negative, we will look toward hardware. Good luck

Run this test for 36 hours

Driver Verifier
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.
Driver Verifier - Enable and Disable

Also give me the new dump reports.
