IRQL_NOT_LESS_OR_EQUAL (please help).

View attachment View attachment

Quick explanation. My SSD broke, RMA'd it, got my replacement, installed Windows 7, all necessary drivers and software. All was well. Then I accidentlymisplaced some important folders etc. easiest solution was to reinstall Windows which I did. Now every time I try to install drivers for my graphics card I get the IRQL_NOT_LESS_OR_EQUAL BSOD.

If the attachment worked properly, all the info should be attached.

So far, I've tried Memtest, but the RAM is fine. Using a different version of the drivers, but I get the same BSOD upon restart anyway. And I'm out of ideas right now. Although I'm amost certain it has something to do with my GPU or it's drivers.

Would really appreciate any help on this. Thanks!

EDIT: This is incase the attachment didn't work correctly.

Do you have any .dmp files for us to look at. Pics of CPU-Z every tab would be useful too :) If your .dmp file is too big for the site could you upload it to rapidshare :)

Yes that helps some. A couple more might be helpful.
There is a bit of initial confusion your dump file reflects an issue with
igkmd64.sys which I believe is an Intel based Graphics chipset, but your system specs show an Nvidia GTX 580.
Is it possible that you have an integrated / embedded video card on your ASRock motherboard, and is there a way, if you are using an add-on card to disable the integrated card in your System BIOS?

An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.

Arg2: 0000000000000002, IRQL
Arg3: 0000000000000001, bitfield :

I can uninstall the integrated graphics all-together in the Add/Remove Programs section. Going to check on that now. I'll update in a little while. Just downloading Service Pack 1 (AGAIN!)

In the most manly way possible...I LOVE YOU :D Well, I installed my graphics driver, and finally got not only to the login screen, but to my desktop! :D

Shouldn't get too excited just yet, just incase. But I'm pretty stoked about coming this far, as simple as the solution was. The annoying thing about all this is on both my old SSD and the temp HDD while waiting for this replacement, I had the Integrated Graphics Driver installed, and never had any issues with the nVidia Graphics Drivers before. I guess it was just fluffing me around this time eh? Or I installed the Integrated Graphics Driver AFTER I installed the nVidia driver (something I never done pretty much every time I had the BSOD).

Anyway, thanks man. I really appreciate it. And if I do get anymore issues (hope not!) I'll post the dumps here and see how people can help.

Thanks again! :)

Glad to hear you are having a bit of better luck now. Thanks for posting back and updating your thread with your information.
Yes if Blue Screens persist just post the most recent dump files and we'll have another look.

I had to install a different driver today to the one I got working yesterday. But it installed without any issues. So I'm pretty sure the Intel Integrated Driver was the issue. Still hoping for no issues, and thanks for all the help :D


Noob Whisperer
You bet and keep us posted. Lot of good people here who are lot better at getting to the bottom of these Blue Screen issues than I am, post back if anything else comes up, and ....
Good Luck

Everything seemed to go well. Although, for My Music, My Pictures and My Videos, I made folders with exactly the same names, but it left behind folders on C that were titled just 'Music,' 'Pictures' and 'Videos.' Apparently, despite having 'My' in front of the 'videos' and 'pictures' etc. the locations for them was C\Users\Brett\Music and C\Users\Brett\Pictures etc. No 'My.'

Still, the folders moved fine. I'm just hoping that music knows to make it way to the correct folder when I copy a CD off. Thanks again dude :D

The "My" is a legacy from Vista/XP. Theoretically, "My Music" will be "Music". A bit like Documents and Settings folder, you cannot access it, but you can through its real name of AppData.

It's for all those folks who upgrade so they can find their folders.

Now, If something goes missing,, that IS the time to worry!!

And, to be really honest, don't keep documents, music, pictures or videos on your system drive. Move them to another drive or partition away from your main system (C:) drive. :)

Yeah, even though I have the remaining 'Music,' 'Pictures' and 'Videos' folders, I imported a couple of CDs to iTunes the other day, and the music made it's way to the right folder (the 'My Music' folder on D). So all it well! :D

Thanks for the replies again guys :)
