    Hello, Thanks for the help. I followed all of the instructions in the Read first post and I am still having trouble.

    After running all of the recommended software, It appears I have something affecting the MBR.

    A friend dropped off an Acer Netbook with Windows XP Home installed. It randomly freezes and can only be shutdown by holding the power button. Sometimes it only takes a minute before it freezes, other times it takes 20 minutes. It seems to take longer to freeze in safe mode, but still eventually freezes. I know Acers are prone to overheat, so I loaded linux from a USB drive and it ran flawlessly for 2 days without freezing.

    I have followed the Read Me first as close as I could. Please help, I'm stumped.

    Thanks.
