    Apparently, you've been tampering with the Registry or running some type of tweak software. Windows 7 does not normally need any tweaks and third party software that does will usually damage the install.

    I suggest trying this first: Repair Install

    It that doesn't work, a fresh install is in your future.

    Tweak prefetch tool i tried it but got an error so it never worked. So it can't be that whats causing the errors. I have done the msconfig link you sent me on this post!

    The stackhash error is caused by Data Exception Prevention (DEP) and could be caused by malware. It can also be caused by errant software that you are attempting to run or have run that corrupted the Registry. All the DLLs you have indicated are Windows core drivers. Since you stated you ran the System File Checker (SFC) command and no errors were noted, it would appear the system drivers are intact.

    Run the MBAM scanner using this tutorial: Malwarebytes Anti-Malware Free
    Download the free version and do NOT select the trial. Also note that MBAM should be "Run as Administrator" when you execute it.

    Also run the Kaspersky TDS Killer using this tutorial: Kaspersky TDSSKiller: Detect / Repair TDSS Rookits
    This scanner should also be "Run as Administrator".

    Report back any hits.

    It can't hurt. No single AV scanner finds everything.

    This is a good one for finding Registry hacks. You might give the free version a try. Use the Emergency Kit Scanner only for the time being.

    Right will i run both of those links you sent me then? TDSSkill and emisoft?

    I'm hoping its an virus and not something thats broken.

    When i tried to run windows defender offline on my external harddrive it gave me a formatting error last night?
