I've been using a new laptop with Windows 7 professional. Occasionally, the whole system will lock up for a few seconds before it comes back to normal. During the freeze, mouse can't be moved, keys are not recognized, music playback stops.... it's like there is a global mutex been locked on and not released. A easy way to reproduce this is to minimized the current window. It doesn't happen 100% but it's quite very annoying.

Any help to get rid of this is much appreciated.
