    There are a few things that I see in Speccy that might need attention.

    First see if there is malware on your machine. Yontoo is a Potentially Unwanted Program (PUP).
    A few on-demand scans will identify and remediate any malware on your system.

    Restart your machine in case there are any system operations pending

    Click here to download Old Timer-TFC.
    >> save the application to your Desktop.
    Old Timer-TFC is a standalone application, there is no install.

    !!!!! Save your work and close all open windows.
    TFC will close ALL open programs including your browser!

    Right click, run as administrator TFC

    Click the Start button to begin the cleaning up temporary files and folders.
    !!!!! Do not work on other things while TFC is running - most applications use some sort of temporary files. Just let TFC run by itself on the machine until it completes.

    Restart your machine immediately after TFC completes.

    AdwCleaner is a two step process. Scan then Clean

    Click here to download AdwCleaner (author: Xplode)
    --> save the application to your Desktop.

    • Right-click AdwCleaner.exe on your Desktop and select Run As Administrator to run the scanner with full privilege rights.
      AdwCleaner is a standalone executable, there is no install.

    • Click on the Scan button.
      • AdwCleaner begins scanning your system. It might take some time to complete.

      • Review the detected objects grouped under each of the tabs.
        --> If there is something you KNOW should NOT be cleaned, clear the checkbox next to the object. If you're not sure about an object, paste the scan logfile (AdwCleaner[S#].txt) in a new post for a member to review and advise you.
        Otherwise, go to the next step.

    • After the scan has finished and you have reviewed the objects to be cleaned, click on the Clean button.
      • Answer OK to the close all programs prompt, then follow the onscreen prompts.
      • Answer OK to the restart the computer prompt to complete the removal process.
        The AdwCleaner log file is opened in your default Text editor when the machine has restarted.
        Each time AdwCleaner runs, the log file number [#] is incremented, the highest number is the most recent. There are two log files, one for the scan (AdwCleaner[S#].txt) and one for the clean (AdwCleaner[C#].txt).

    Paste the entire clean logfile (AdwCleaner[C#].txt) in your next post.
    --> AdwCleaner logs are located in the C:\AdwCleaner folder if you need to reference them again

    and finish this exercise with:

    So why did you say upgrade to windows 10 32 bit then clean install 64bit unless you determined that after you posted?

    I was just responding to your statement!
    LOL - because I had not seen the Speccy when I posted that

    Thanks guys, i noticed yontoo after posting and reading the speccy report, I've removed it. I had a look on the toshiba site, found drivers etc, but i couldn't find the bios update cereberus mentioned. I've uninstalled a few other old programes i noticed that i don't use anymore. I read further that with macrium reflect the version 5 doesn't uninstal properly, so i installed v6 overtop then uninstalled it. I am currently re trying w10 upgrade, i'll post the results when it's done.

    See what you can find here - enter the model or serial number to get to the right support page.
    Official Toshiba Support | Toshiba
    FAQ: Where is my model and serial number on my Toshiba laptop

    When I posted the BIOS 3.4 update - I didn't know your exact model (there are a few Toshiba Satelitte Pro P300 models), so I couldn't be sure it was for your machine

    Once you know the sub-model, please put that in your specs - thanks

    Windows 10 has finally finished installing, during my 6 attempts I believe the three key factors in overcoming my problems were

    1 This PC's processor doesn't support a critical feature (NX)
    Looking at the "Data Execution Prevention" tab under performance options stated that my laptop supports DEP,
    so I ticked the "Turn on DEP for all programs" check box on and that solved that issue. which lead to:

    2 page fault in non paged area pssnap.sys
    I had Macrium reflect V5 installed, Macrium seems to install it's own version of pssnap.sys, which it fails to restore the original when you un-install the program.
    The solution is to upgrade to version 6 and then un-install Macrium reflect. I checked the properties of both pssnap.sys files, identical size with totally different dates.
    So the version 5 file is not compatible with Window 10.

    3 UN-installing yontoo, may or may not have made a difference to the upgrade installation, but definitely not wanted on a P.C
    I can mark this thread as solved. Hopefully someone else may find what finaly worked for me, may work for them.
    Now I can put my 2nd hdd, wifi etc, back in.
    Thanks again
