  1. Hi Guys
    I am having a pretty constant error where XP Pro crashes and i get "Driver_IRQL_less_or_equal" . I am running a

    Biostar M7NCD pro - Mobo
    Crucial 512mb DDR Memory
    Aopen Geforce FX5200 128mb Graphics Card
    Maxtor 60GB 5200rpm

    I am wondering if there is anything i can do to fix this issue as it is very fustrating. I flashed the bios a few months back with Pheonix labs bios and it updated fine but i am completely stuck on what if anythign i could do.
    Please give me a hand if you know anything.

    Regards
    Joe

    Hey
    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)
    Driver_irql_not_less_or_equal
    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 www.memtest.org

    let it run for at least seven passes.

    Regards Howard :wave: :wave:

    Uhcd.sys

    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.

    Irql_not_less_or_equal

    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.

    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.

    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
