Help with "IRQ not less or equal" suddenly occurring on bootup

globalste said:

First post here, apologies if I get something wrong.

I couldnt create a BSOD file, so I had to take a photo - hope this is ok. I have also attached a bootlog file.

My computer was working fine and I hadn't even installed anything new when one morning it simply would not boot without BSOD. It will however boot and work using Safemode with Networking, so I figure it has to be a driver issue?

I have gone into startup system/tools and reduced it to the bare minimum but I still get the issue, so then I tried to run the perfom report but it will not let me in safe mode. I have tried to run a repair from Windows 7 bootup cd, but it comes up with nothing, ditto on memory check.

So attached is the BSOD image (again, sorry I couldn't use the program to grab it)


and the bootlog file (not sure how useful this is as was booting using minimum stuff anyway)

I know that my machine isn't technically meant to run Windows 7, but it was designed for Vista and so many of the drivers I was able to use from Vista because W7 supported ones were never released (eg soundcard and video driver iirc)

Computer is
An Acer Aspire 5102 with the AMD TL50 processor
4GB ram
120GB hard drive

It is running Windows 7 Home Premium (single licence) 32bit version
The computer is over 3 years old, the OS is only 1 year old and I have had no problems with it up until the morning of April 1st when the problem started.

I foolishly setup no system restore points or anything else, so have no backup to run the machine from. The only thing I have is an Acronis image from before I upgraded to Win7.


I have since bought a Dell XPS because I needed to have a new machine ASAP and am now trying to fix it to sell it. Any help is greatly appreciated.

Many thanks for the reply.

I have downloaded and attached the file - took quite a while to do!

This morning I used DriverMax to see if I could find any really updated video drivers (when I built this machine with W7 in December 2009, the latest drivers would not work), I found one that was for December 2010. I thought "what the hell" and installed it (at least I think it installed properly). Anyway, I have just rebooted after adjusting the minidump settings as suggested and.... the bl**dy thing started up normally.

So do you think the video card driver was the culprit or just a coincidence and it will not run again in a few restarts?

Yes,maybe,if you dont had/have again any bsod.(i hope not)
Btw the minidumps you uploaded are 3 month old,do a disk clean to clean everything and old minidumps also.
I quess we must to wait for results.
A new bsod and new minidumps maybe?
