    I have that board too and it was constan problems at first. Same error especially when playing games or multimedia.It turned out the default memory timmings are too aggressive. I have mine set at 6-3-3 CAS 2.5.

    thanks very much for that, it does drive me crazy doing that every time i am doing something, it is as you said always in the middle of what your doing!!

    Can i change the memory timings in the bios setting then?? Please let me know where i can change them to more reasonable level.

    Thanks again

    IRQL error

    I checked my memory Timing settings and they are already set to 6-3-3 CAS 2.5. Any other ideas would be greatly appreciated as it is occuring more often!!

    Can you give us the exact error message plus all the numbers?

    You might want to go HERE for an explanation of Windows stop messages.

    Similar message

    I am getting a similar message on one of our Dell machines, a Dell 4700. I am running Win 2000 Pro and originally it had a Dell 1700 printer attached with no problem. I moved that printer to another location and installed an HP LJ 1200. Almost immediately we started getting blue screens with stop errors when we printed. I called Dell and they had me download the latest system flash and it seemed to clear up for about a week. Then the errors started again. It only happens when we print but not every time. The complete message is:

    Stop: 0x000000D1 (0x0000015, 0x00000002, 0x00000000, 0xEB6AAB46)
    Address EB6AAB46 base@EB6A8000, DateStamp 3E25BA6E - uhcd.sys

    Then it begins a memory dump.
    If anyone can help I will deeply appreciate it!

    Hello and welcome to techspot.

    Go HERE and scroll down to your error message.

    It might be worth downloading and running Memtest86+ you can get this from

    let it run for at least seven passes.

    The stop error is telling you that the problem is with uhcd.sys (USB Host Controller Driver). Try reinstalling or replacing that file. Check for a service pack that updates it.

    Ok guys so my Pc finally crashed out again after being fine for a week (Think it does it on purpose). So here is the message i get when it crashes.

    Biostar M7NCD pro - Mobo
    AMD Athlon 2200+
    Crucial 512mb DDR Memory
    Aopen Geforce FX5200 128mb AGP Graphics Card
    Maxtor 60GB 5400rpm

    A problem has been detected and windows has been shut down to prevent damage to your computer


    If this is the first time you've seen this stop error screen, restart your computer.
    If this screen appears again follow these steps:

    Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware manufacturer for any windows updates you may need.

    If problems continue, disable or remove any newly installed hardware or software. Disable bios memory options such as caching or shadowing.
    If you need to use safe modeto remove or disabke components, restart your computer press F8 to select advanced startup options and then select safe mode.

    Technical Information:
    ***STOP 0x000000D1 (0x3F3F3F87, 0x00000002, 0X00000001, 0Xbac5eb80)

    ***ndiswan.sys - address BAC5EB80 base at BAC5400, datestamp 41107ec6

    Begining Physical memory dump
    Physical memory dump complete


    What do you guys think? anything that i can fix, By the way when the system crashed I was using Azureus (bit torrent application) amd Windows Media player if that helps.

    I would really appreciate any help you can throw at me.

    Cheers guys

    ndiswan.sys problem

    Your last stop error had something to do with this file (ndiswan.sys) which has something to do with Windows networking or your NIC. I would try to restore that file from the XP CD and reinstall your NIC drivers. Also, search Google for "XP stop ndiswan.sys error" - you should find enough information to fix this.

    Good luck
