    Startup fault Root cause found unknown bugcheck f4 parameters =0x3


    I have an acer laptop running Windows 7. I did a windows 7 update in the morning that afternoon I had problems re-starting the computer. Internet Explorer wasn't working saying page could not be displayed and Norton was playing up as well. I have completed a startup repair and got this error message;
    Root Cause Found
    Unknown bugcheck f4 Parameters = o x 3, oxfffffa8007efe230, 0 x fffffa8007efe510, 0 x fff800033d70do.

    Repair Action: system files integrity check and repair.
    Result failed. Error code = 0 x 45d.
    Time taken - 1569027ms

    I have now tried to start windows normally and it has taken about 20 mins so far and just a black screen.

    Can anybody help please.

    Hi and welcome to the Forum
    See if you can boot into Safe Mode. If you can try a system restore to a point before the update took place!

    Tried that one.
    I am only able to restore it back to the time when the last update was.

    newtonspinks, a 0xF4 bugcheck is usually attributed to failing storage hardware.
    The fact that it coincides with a Windows update is odd but what you're describing is worrying.
    I recommend you backup your data, you can follow this tutorial on a different PC then boot the USB
    onto the laptop :: Emergency Kit - save your files from a dead OS ::

    Then you can test the HDD:

    1. Perform a Disk Check | Disk Check
    2. Then Post the results following | THIS METHOD
    3. Download SeaTools for Windows if you don't want to use a CD to test the HDD you can use YUMI – Multiboot USB Creator to create a bootable USB (instructions are found at the bottom of both pages).
    4. If SeaTools for Windows is unable to recognize your HDD visit HDDdiag and follow the instructions.



    Being it's a laptop the temperature concern is always present boot into the BIOS and look for
    PC Health something of that nature to give some estimate to the temperature.
