Can anybody explain this:

*** STOP 0x000000D1, (0xBFD4EF59, 0x00000002, 0x00000000, 0xBFD4EF59) IRQL_NOT_LESS_OR_EQUAL

***Address BFD4EF59 base at BFD1D000, Datestamp 3b38910a - ALCXWDM.SYS
***Address BFD4EF59 base at BFD1D000, Datestamp 3b38910a - ALCXWDM.SYS

Beginning Dump of Physical Memory.

What are those all about. Really confused with this.

Thanks,

You did'nt say what OS you are running but "Stop 0x000000D1 or DRIVER_IRQL_NOT_LESS_OR_EQUAL---" is usually an error which occurs when a driver tries to access an improper memory address. Check for unsigned drivers, recently installed or updated antivirus programs, disk utilities, and backup programs. ie ALCXWDM.SYS

Sorry you also wanted an explanation
Reading this stuff can be tricky
The stop message has four parameters
1 Memory referenced
2 IRQL at time of reference
3 Type of access (0x00000000=read operation, 0x00000001=write operation)
4 Address that referenced memory

Check technet site at Microsoft for in depth explanation

Done a little more research
Check backup program updates, any new anti virus, DVD and CD mastering tools.
Check driver name (at end of stop message) and disable, roll back or remove to see if this resolves problem
If you have installed anything new uninstall. Use last known good command to roll back and get back in, then remove software to check

First boot into safe mode.

(press f8 while booting)

Remove the sound card using add/remove hardware (you may have to show hidden devices)

The driver for the Avance AC'97 Audio is what is causing the problem, not memory.

If it is was memory, you would be getting a whole different message.

Thanks anyway.
I just saw your reply today. I definitely stick on it (did not sleep) until i found a generic type of sound driver from Realtek company.
Finally it worked without the blue screen.

Thanks again.
