    BSOD irql not less or equal


    Hello

    Some weird things are going on with my laptop recently. After random freezes and BSOD's I reinstalled Windows 8.1 which solved the issue for a couple of days. Until now I got a BSOD while I was watching a stream (flashplayer). You can find the dumpfiles in the zip.

    Thanks for your help!

    I'm sorry, the tool didn't work the first time. After a second run it worked. Here is the file:

    The cause is the iaStorA driver which is a driver from Intel Rapid Storage Technology.
    But you don't have this installed.
    Please move the following files to the D partition and see if it makes any difference.
    Code:
    iaStorA	c:\windows\system32\drivers\iastora.sys
    Intel(R) SATA RAID Controller Windows	c:\windows\system32\drivers\iastorav.sys
    Intel RAID Controller Windows 7	c:\windows\system32\drivers\iastorv.sys
    Code:
    *** WARNING: Unable to verify timestamp for iaStorA.sys
    *** ERROR: Module load completed but symbols could not be loaded for iaStorA.sys

    I did what you said. After a restart I can't boot anymore.. It goes straight to a BSOD and restarts. I'm now 'refreshing' my pc and hopefully post the dumplogs later. I guess it has something to do with these drivers.. I deleted them from system32 and got them backed up at D.

    Let me know if refreshing gets you back to normal booting.

    You might need to check your manufacturer for the IRST software.
