BSoD - 8086 (I thought this was an old processor!)

  1. Hi,

    I have a Dell Dimension that, until recently, was VERY stable. No errors, no BSoDs!

    Hardware, etc. tests all done and passed.

    Now I get this 8086 STOP code at any time. When apps are running, when they're not; after a few hours up-time, after a few minutes. Crazy!

    Any help gratefully received, thank you very much.

    All BSoDs, point to iaStor.sys , and since this driver file of yours states made in 2004, I'd say it needs updating ;) (god knows how you got this old version put on recently)

    Here's all your driver updates:

    Thank you very much kimsland. :wave:

    How did you see iaStor.sys? I used MS debugger and !Analyze but didn't see that file!

    I bought the machine in May 05 so maybe it came with it?

    Can I just delete the old one and copy a new version to the directory or is it more complex than that?

    I can make it do a BSoD by runing, ironically, the Dell Support Centre self checking software!

    Could this help debugging?

    Although you don't need to do this anymore, since I have done it for you ;)
    Just go to >> Dell Support, and update all your drivers

    I updated iaStor - from the Intel site in the ned as the Dell site was ... odd - easy as pie.

    I ran the check thing that causes BSoD and ... nothing! No BSoD!

    Fingers crossed it's all good!

    Thank you very much kimsland, you are an absolute star!
