Bsod error: driver_irql_not_less_or_equal

[Oregoncomptech]

driver-irql-not-less or equal 0x000000d1 (0x00000060, 0x00000002, 0x00000000, 0xba41b4df)

usbehci.sys - Address BA3cB4DF base at BA3c8000, DateStamp 41107d62

Is my Bsod error code. And it happens when i use my flash drive, usually when trying to copy files off of it or onto it. This computer was infected with virus's also. I have worked on this all day but no luck.

Any ideas?

In addition to memtest, I'd check your USB controllers under device manager for conflicts, possibly do a re-install of your chipset/USB drivers.

Before trying to second-guess the problem by randomly plugging/unplugging bits of hardware, how about analysing the BSOD message? As horrible as they might appear to the unqualified the BSOD is a diagnostic tool, albeit one that requires a bit of effort.

My money's on usbehci.sys being infected by a virus, in which case ask yourself:

• Does the OS need this file to boot?
• How do I disable this system file on bootup?
• With this file disabled does the OS now boot?
• How can I restore the original file so my USB peripherals work again?

It looks like a pretty straightforward rootkit virus removal job to me.

Thank you for all your reply's. Its late so this might not be written well so bear with me.

First off, first thing i did was check for dust and over heating, and it was fine.

Then i uninstalled and reinstalled all the usb devices using usbehci.sys. Still giving me the Bsod though not as fast as before i can actually open some folders on the flash drive. Then after that i replaced the usbehci.sys file with a new one off the windows cd and updated the devices. Still gives me the bsod. I am about to backup what i want off it and reformat it.

Also i get a random lockup and bsod having to do with an infinite loop of a certain ati2dvag.sys or exe cannot remember atm.

Seems to be cleaned up also checked it with hijackthis and ran malwarebytes+ Avira anti virus.

But i am leaning toward a corrupted OS. Something having to do with the infection.

Thanks,

John

Hi John,
If you wouldn't mind could you upload the minidump file to the forum - I need experience analysing them. Maybe the usb and ati drivers are used by the same software, before crashing?

P.S If you'd like you could run this program, which will automatically send me the minidumps.

Thanks
Philip

Test your ram, memtest86 or the like.

Use your IR temp gun and take the temp of the northbridge, ram, cpu, southbridge, video, etc, look for anything over 60c.

the IRQ_NOT_LESS_OR_EQUAL means there is a problem accessing a block of memory, and 9 times out of 10 when I've had it its one of three things, overheating, bad ram, or wrong drivers installed.

+1, I can almost guarantee it's one of these things. Don't be so quick to think it's a corrupt OS. The blue screen is telling you what's wrong. If you n/p you could be right back at the same point if let's say it's the ram that's bad. Run memtest and get back to us.

Ok been testing the ram for over 4 hrs now, no errors.

Usually if memory is the culprit the BSODs would be random and list different device drivers as the culprit.

This is taken from the MSDN Help:

This bug check is issued if paged memory (or invalid memory) is accessed when the IRQL is too high.

The error that generates this bug check usually occurs after the installation of a faulty device driver, system service, or BIOS.

If you encounter bug check 0xA while upgrading to a later version of Windows, this error might be caused by a device driver, a system service, a virus scanner, or a backup tool that is incompatible with the new version

Because it is a specific driver(s) that is causing the BSOD, most likely it is system software - that recently was upgraded or installed. The minidump will give more clues

This: ati2dvag.sys makes me think it's an ati device of some sort. Video drivers? Wouldn't be uncommon.

Is the BSOD throwing any kind of error code? 0x********** you can normally pin point on what the problem maybe... see here, http://www.aumha.org/a/stop.php

I'd try installing the chipset/southbridge drivers specifically for the board you're working on as they can vary, the motherboard section of SIW will give you more information as to what you're looking for.

Possibly a clean set of catalyst drivers as well?
