This problem may occur if you are using a version of the DirectCD component of EZ CD Creator that is incompatible with Windows XP.
Resolution- • If Easy CD Creator is still installed, uninstall it, or uninstall only the DirectCD component.
• Rename the Udfreadr.sys and Cdudf.sys files that are located in the %Systemroot%\System32\Drivers folder to Udfreadr.old and Cdudf.old.
• Go to Start/Run/Regedit and Delete the following registry keys and then Rebooot:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UdfReadr
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\cdudf

I am assuming that the error occurred on a regular startup.

Have you tried booting into 'Safe Mode'? If not, restart your computer, press the F8 key. (This will give you a list of ways to start your laptop. If the error occurs here, this is a somewhat serious problem.

Please let me know what happens and provide plenty of detail, the more detail the better. Binary Bob

Hi,

The Blue Screen Error IRQ Driver not less or equal is a memory problem. Basic things you can do is reseat the memory. However, I highly suggest to contact Dell and have them guide you in doing a Memory Diagnostics. They should replace it if its faulty.

Win XO Pro displays MSG: "IRQL_NOT LESS OR EQUAL" on blue screen. Sounds like a hardware compatibility problem with SMCWPCI-G2 wireless card adapater. Any hints on how to solve this?


This almost always seems to be an IRQ conflict that the BIOS can't resolve with its plug n pray skills. When this conflict is passed to XP at boot-up time, XP panics and blasts you with this error message.

Before you start pulling cards, go about pulling cards, go into the BIOS and change the IRQ of the on-board compnents, if you can, and also disable any on-board components that are not needed. (such as the parallel port, on-board ethernet connection, etc.)

How to remove built in wireless card on Toshiba Tecra M2v-S330


Assuming you are in XP:
Start in safe mode and either try to fix your Configuration (did you installed anything conflicting with you WLAN card?) or simply disable the card from your configuration in Control panel, system, Hardware tab, Device manager
Check if an updated driver exists for your card: latest SP3 is sometime conflicting with older device drive.
Let me know if working and do not forget to rate the solution

IRQ nOT LESS OR EQUAL HEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEELP


irql not less or equal sounds like a graphics driver problem. All you needed to do was boot up in safe mode and remove the gfx driver and the OS would have rebooted with the default driver and then you could have reinstalled it

Has memory been added to this laptop recently or any changes been made?

the irq error/bluescreen is mainly due hardware issue and most of the time in my experience, memory.

Re-seat your Ram, go into the bios and reset all back to factory defaults. Unplug all devices, as well.
