Hi Everyone, I have a really irritating problem with my system running under Windows XP.
My system keeps regualrly crashing leaving me with a blue screen and the following error message. "Driver_IRQL_NOT_Less_OR_Equal Stop: 0x00000000D1
w22N51.sys Address F8067988 base at F7FF3000

I have been on to Microsoft.com, where there seems to be a miriad of "fixes" but nothing that relates to the above message.

Any ideas anyone

Desperate
Thanks Jill

STOP 0xD1 (DRIVER_IRQL_NOT_LESS_OR_EQUAL) means a kernel‑mode driver tried to access pageable or invalid memory at too high an IRQL — in short, a driver attempted an illegal memory access rather than a simple user‑mode app fault. This is a driver‑level problem and the crash message usually names the suspect driver. (learn.microsoft.com)

The file w22n51.sys maps to Intel PRO/Wireless drivers (Centrino 2200/2915 family) and has a known history of causing D1 crashes under certain network conditions; Intel published advisories recommending updated drivers for affected versions. Because some users have reported the crash reproducing during network activity or when running specific apps, it’s important to confirm whether the wireless driver is actually the culprit before replacing hardware. (intel.com)

Practical troubleshooting sequence: collect the minidump files (default: C:\Windows\Minidump) and run a quick scan with BlueScreenView to see the referenced driver, then use WinDbg (or similar) for a deeper !analyze -v stack trace and symbol lookup. Verify the physical file path and file properties of w22n51.sys on disk to confirm the vendor. If the Intel driver is implicated, update it from the laptop/OEM site or Intel; as a diagnostic step, disable the wireless adapter in Device Manager to see whether crashes stop. (nirsoft.net)

Hardware and stress checks: follow ’s hint and rule out RAM by running MemTest86 (bootable USB) for several passes and by swapping/reseating DIMMs. For driver debugging on a test machine, enable Driver Verifier to force reproducible failures and gather richer dumps — but only on a non‑production system (Driver Verifier itself will provoke crashes). If updates aren’t available, keep the offending device disabled or use an alternate driver until a vendor fix is obtained. (memtest86.com)

You ll have to be a bit more specific about the issue, is there any particular application that you are using when it does that? Or maybe on the times when you are using more demanding applications running on your machine?

It could happen due to a few different reasons, so let us know and maybe we would be able to help you out.

I've always seen this be a bad RAM problem. You can try and swap your sticks (reseat etc.) but more then likely one of the sticks is going bad and you need a replacement.
