WIN2000 PRO STOP ERROR

More information required for definitive answer:
1) What unusual processes show up in task manager when this happens?
2) Does the same thing occur for someone else logged into the pc? If not, it could well be the user's profile. If so,

CorruptMSOffice - uninstall, delete Office folder & reinstall

OR

Corrupt Printer driver - remove printers, ensure drivers are replaced when reinstalling printer

Have you checked device manager to verify that each device is configured correctly and there are no resource conflicts?

What was the last device added before this error happened? Remove it and see if the error continues.

My first guess would be to check the memory. Use e.g. the tool DOCMEM to test it.

If the memory is not the problem, look for faulty drivers that where recently installed

Check out the Microsoft Knowledge Base for this one.

Just use the error message "Driver IRQL_Not_Less_or_Equal" as the search criterion and you will find plenty of information about these errors.

They are often related to a memory fault or indeed a processor fault

Good luck

We have not added any new hardware or software recently. The problem is getting worse. It used to happen 1xweek now 10xday. Most of the time the monitor goes poof and it just restarts without even an error message. I can get it to recreate the problem by backing up a large file on to the hard disk or printing. Sometimes it just chooses to do it whenever. Now it takes 3 times to restart the computer.

If several devices are sharing IRQ11, then take them all out and install them one at a time. Move the cards to different PCI slots to mix up the IRQ assignments. Make sure to reboot in between each new card.

*Much* more system info needed.

What BIOS and VER? What motherboard? Specs of m/b etc. SP on Win2k box? What hotfixes after SP have been applied? Video card? Video card driver version? etc etc etc.

Given the fact that this problem seems to be happening v.often but iregular in what causes it I would instantly suspect a hardware fault. My inital suspects would be firsly RAM, then motherboard, or thirdly the processor overheating.

You can check the first by changing the RAM and seeing if that helps. And the last one you can try by touching the CPU heatsink. Anything >40 oC or 'warm' is bad.

If they don't work, replace the board.

Some may suspect the hard drive, but in my experience, windows 2000 can keep running with a hard drive error. Plus it will definatly show up in the logs as an error in /dev/hd1 or similar.

Its definatley NOT software if it happens radomly indifferent programs and at different times.

The same problem occurred with my network. It took a week to track the cause. AMD sometimes conflicts with Ethernet drivers provided by the server for internet and Networks. I resolved the problem by loading RASpppoe Ethernet driver. It worked. Theother Ethernet drivers seam to use up to much memory-I think-still don't know forsure; but the IRQ is part of the problem. PS, the o/s of my network is WIN2k as well.
