    No, my windows update just says "An error occurred while checking for new updates for your computer" (error 80072EFD). It just won't even let me search for the updates. oddly enough I looked at the history for updates, and there was one yesterday that I didn't even know about (Hotfix KB981889).

    I think it is time to format and re-install Windows, all the Windows Updates and drivers, and MSE with a temp file cleaner. Going on-line any length of time, with no anti-malware protection put you in this situation

    That's why I have no malware or spyware correct? Ran three different programs and none detect it. Thats definitely not problem. It's more than likely a CPU hardware problem.

    I have run into a bug like this before. The lsass.exe is running rather high in read/write bytes. The solution to my problem, which had symptoms very similar to what you are experiencing is below. BTW it won't harm anything or change any system settings.

    Create a new user profile. Save it and log out of your current one. Log into the new profile and allow it to finish setting things up. Run a few programs, it doesn't matter which. Close them. Log out and then log back into your old profile. This should allow you to reset your system as what may well be happening is your user profile is corrupting. These symptoms will reappear and the ultimate solution is to copy all necessary files etc to the new profile or at least share access so you will be able to use them in the new profile.

    I go for reformatting and reinstall the system to solve the problem... that would make the machine runs faster.

    Here's a link for the specific error you're encountering:

    Basically, you need to install the latest Windows Installer. You can Google that easily. With the wrong installer, you can't install the WGA verification tool, and hence can't update.

    After doing the steps above, Windows Update has found a total of 150 security updates.

    This cured all my update issues, (couldn't update), but I was dealing with an XP box.

    You should be able to simply kill Windows Defender in task manager, at least temporarily.

    iTunes is also known to semi-brick Windows machines. Apple planned it that way.

    M$E, has been getting terrible reviews because of its wretched detection and disinfection rates. In short, just because M$E says you don't have an infection, doesn't mean you don't have an infection.

    IMHO, "Malwarebytes", is as useless as t*ts on a boar (Your results of course, may vary).

    The temperatures on your machine, are not only "OK", they actually seem stellar, very low.

    Since none of our suggestion have helped in any way, and you're adamant we're wrong, and the problem is a hardware issue with the CPU or the board, just go out and buy a new computer. That's about all that would settle those issues.

    If you have been online for some time with no A/V, then it might be worthwhile running a decent scanner such as;
    ( This will take some time to scan but for the best reasons.)
    With the 'optimise for best performance' in the post above (#34), this will turn off all the glass and Aero effects in Vista, and the system will run faster because the graphics chip(s) will have less to do.
    I would think you know about and use a program such as 'CCleaner'.
    I have also used this program dozens of times to help when the system starts to get sluggish;
    Before you run a scan, create a restore point, and in my experience this is a very solid program, I have used it on Vista ,7 and 8.
    Once this program is installed, use the 'scan and repair' option.
