Windows 7: BSOD: IRQL Not Less or Equal

Check to see if there's a BIOS download that says it's in a BIOS Recovery format (BIO). My Intel MB BIOS updates always give that as a separate option. I keep a USB drive loaded with the last version for just such mishaps. I had to use it when I mistakenly updated to a wrong version. But I'll never admit to it. :)

Ken, if I'm not mistaken, he has a bios recovery on his driver CD, plus he should have a renamed bios that he can flash his last bios to if he did it right.

skrillek, look on your USB drive you used to flash the bios and tell me what files you see on it. The names are especially important.

What is the whole file name? Many ASUS boards also have a BIOS renamer utility.

Gary, he should have 2 files. The one he flashed and the renamed one to use for the bios flashback, if he used the renamer utility. That was why I asked for the names. But, he is supposed to have a bios recovery file on the driver CD. It will be an old bios, but it will reflash it. I know you know most of that if not all of it.

I hadn't thought of that Steve because I never used it. I did read about it to recover a bad BIOS flash, I think.

I can't read dump files, but hidclass.sys is a USB driver. It is usually in your Chipset drivers. It can also be caused by third party programs which have drivers that conflict with it. Hopefully that will be in the dump files if that is the case.

It may also be helpful if you would tell us exactly what you did to get the PC to boot again.
