Mysterious crashes and the blue screen of doom!

By paradoxx
Nov 4, 2006
  1. Hey everyone, firstly, i want to apologise as this is such a long post, but i wonder if you can help me.

    A while ago my psu had a bit of a mental and sent what seemed like to be a power surge through my system. All of the fan led's lit up for a second, and went off. I then couldn't turn my computer on at all after this.

    Luckily i had a spare psu lying around, which i installed, and to my relief the system started fine, but randomly started to crash for no reason from then on.

    I knew that i would have to buy a new psu, and while i was at it, i bought a new AMD X2 4400+ and a 400gb Hd.

    When everything arrived, i installed the new hardware, formatted, installed windows... the usual. But after a while, the system began to crash again.

    At this point i figured that it was a hardware fault, but knew that it couldn't be due to the cpu, or psu as they're both new, and i had installed windows serveral times between then and now, trying to fix whatever was wrong, with no luck.

    Last night i left "Microsoft Windows Memory Diagnostic (BETA)" scanning my RAM for errors. It had completed 8 passes using the thorough test, when i woke up. No errors were reported.
    I have previously used "Memcheck" and that said that my ram was fine too.
    The other day i took out all of the ram, and tested each of them by themselves, and in different slots, and different combinations. This came up with nothing either!

    Therefore, i think my ram is fine. (unless there is something i have missed)

    I also checked my graphics card. I was using a "geforce 6 6600 gt" (and yes i know i need to upgrade). I figured that it was this that was causing me the problems, as when i removed it and replaced it with an old "Geforce 4 mx420" my system seemed to run better. I think so far i've only had a few crashes now, compared to much more frequently with the other card. But still, there is something wrong.

    I tried the gfx card in another computer, and it seemed to work fine, until i tried to increase the resolution, when it just locked up and left me with a black screen, with a little white "_" in the top left corner. I couldn't do anything, other than restart.

    This is what made me think it was the gfx. I'm now considering sending the gfx card back for repair under warranty, but want to establish whether its definately this that it causing me problems before i send it.

    Even after removing that gfx card though, i'm getting system crashes. Not quite as frequently, but there is still something wrong!

    In the system log, the last system error reads as follows:

    Event Type: Error
    Event Source: System Error
    Event Category: (102)
    Event ID: 1003

    0050: 30303030

    This really means nothing to me and thats why i need your help. When the blue screen appeared, corresponding to the error above, the main bit that i picked out of it was "BAD_POOL_CALLER". Again, this means nothing to me. I've tried googling it but only came back with that it was probably a ram problem. (but i've already checked this)

    After the crash, windows kindly lets me know that there was an error. So i send the error report, and get taken to this page: http://oca.microsoft.com/en/response.aspx?SGD=bb3811b5-84dd-49c9-819f-6244b2a63f45&SID=10
    Which really is no help as it doesn't tell me which driver is broken!

    I'm now confused as to what steps i should take to sort everything out.

    My last thinking is that its the MOBO, but i don't know how to check for problems with it.

    So overall, my ram appears to be fine, i've got a different gfx card installed, but am still getting these random restarts, i've got a new psu, cpu and hd. and thats about it!

    My system specs, just incase they help are:

    CPU - AMD X2 4400+ Dual core. (NOT OVERCLOCKED)
    RAM - 2GB DDR Ram. Corsair, i think.
    GFX - Geforce 4 mx420 (installed atm) but was previously using Geforce 6 6600gt
    HD - 1x 400GB 1x 80GB
    PSU - 550w
    MOBO - MSI K8N Neo2 Platinum SKT 939
    OS - Windows XP SP 2.​

    Oh, i'll also just add at this point, that whilst looking through my event viewer, i have a lot of "Red X" errors reading:

    Event Type: Error
    Event Source: Service Control Manager
    Event Category: None
    Event ID: 7000
    Date: 04/11/2006
    Time: 01:16:03
    User: N/A
    Computer: A47CCF05627549D
    The PCAMPR5 NDIS Protocol Driver service failed to start due to the following error:
    The system cannot find the file specified.

    I don't know whether this would have anything to do it the restarts at all??

    Thank you to anyone who has taken the time to read this, and i'd really appreciate any feedback at all!!

    If it was me i would get both the gfx card and the mobo replaced!!!!

    From all the testing you have done (nice to see it all posted and explaned) i would conclude that both mobo and gfx have been damaged!!!!

    Thank you.

    Yeah that was my thinking aswell, i've already looked into which ones to buy, now i'm just waiting for some money! lol

    But is there any way of testing the mobo for faults at all??
