  1. I have a Nvidia FX5500 video card on an Intel D845GEBV2 motherboard with 2.4 GHz Intel Pentium 4 Processo. I have 1GB DDR-SDRAM. I continually get BSOD STOP error. The latest mini-dumps are attache. The STOP errors are as follows
    STOP: 0X0000000A (0X00000166, 0X00000002, 0X00000000, 0X804E5433)

    Any help will be greatly appreciated!

    Hello and welcome to Techspot.

    Your minidumps crash at rxp.sys. I can find no reliable info for this driver file. Do you recognise it?

    They have a bugcheck of 7F.


    One of three types of problems occurred in kernel-mode: (1) Hardware failures. (2) Software problems. (3) A bound trap (i.e., a condition that the kernel is not allowed to have or intercept). Hardware failures are the most common cause (many dozen KB articles exist for this error referencing specific hardware failures) and, of these, memory hardware failures are the most common.

    Regards Howard :wave: :wave:

    I think rxp.sys was installed by a program called StarSkin, which isa a program to change the visual appearance, custom styles, and themes. I deleted rxp.sys and re-installed StarSkin, so far no BSOD.

    Thanks for your feedback.

    I am having the same problem with BSOD IRQL NOT LESS OR EQUAL STOP:
    0x0000000A (0x00000116, 0x00000002, 0x00000000, 0x804E5433) I have a Planar for Dell Dimension 8250 Mobo, nVidia 7600 GS 8xAGP video card, Sound Blaster X-Fi Extreme Music Sound Card, 2.8 Ghz Pentium 4 Processor, and 256 Mb of PC 1066 RDRAM for 533 mhz FSB, which I plan to upgrade.

    I get this BSOD often while the computer is booting up, with the Windows XP Black loading screen running. This has lead me to believe that this may be hardware or driver related. However, I checked the Device Manager and all the drivers are listed as signed and in good order. I do not have the rxp.sys file or the StarSkin app. Any opinions on what may be happening in my case?

    "I checked the Device Manager and all the drivers are listed as signed and in good order."

    This means absolutely nothing when it comes to BSOD problems. You may have failing memory or you may need to update the motherboards bios, or your Nvidia video drivers. Have you installed all the Windows Updates?

    The video card is freshly installed, however I wll check to see if new drivers are available. I believe I have all the Windows Updates, but will check to see if there is a BIOS update at Dell. I'll let you know how all of this works out.


    I've done everything TMagic suggested in regards to Windows Updates, BIOS and Drivers. I also ran a series of memory diagnostics using the CheckIt Diagnostic Utility that came with Norton System Works 2006. The memory passed the tests and CheckIt reported "No Error Found" I am still getting this BSOD on an intermittent basis.

    Are there any other utilities or diagnostics that I could use to find out what's wrong? Any additional help would be appreciated.

    Follow the Video Card Question Guide I have in my signature and follow step 3 to rule out any Power Supply Problems.

    Were you experiencing BSODs before you installed the video card?

    Yes, I was getting the BSOD before I installed the video card. The BSOD started cropping up five weeks after I had a new Hard Drive installed (Seagate Barracuda 400 GB Ultra ATA). If the issue were the hard drive or its drivers, would the BSOD have come up immediately after the installation? I'm not sure how related the two are.

    I really think this problem is related to your RDRAM memory sticks. RDRAM needs to be installed in sets. If you have 256MB total, you will have two 128MB sticks of RDRAM installed

    More information about the bugcheck 7F stack overflow at rxp.sys

    BugCheck 1000007F, {8, 80042000, 0, 0}
    Probably caused by : rxp.sys ( rxp+242b )

    This means a trap occurred in kernel mode, and it's a trap of a kind
    that the kernel isn't allowed to have/catch (bound trap) or that
    is always instant death (double fault). The first number in the
    bugcheck params is the number of the trap (8 = double fault, etc)
    Consult an Intel x86 family manual to learn more about what these
    traps are. Here is a *portion* of those codes:
    If kv shows a taskGate
    use .tss on the part before the colon, then kv.
    Else if kv shows a trapframe
    use .trap on that value
    .trap on the appropriate frame will show where the trap was taken
    (on x86, this will be the ebp that goes with the procedure KiTrap)
    kb will then show the corrected stack.
    Arg1: 00000008, EXCEPTION_DOUBLE_FAULT
    Arg2: 80042000
    Arg3: 00000000
