Unexpected shutdown and then restart, upon mouse scrolling

[monkeyj]

This happens virtually everyday on this new computer I got at work.

Suddenly when I'm in the process of scrolling the page using mouse wheel (either browser, or microsoft word document, etc) the screen blinks for a fraction of second, and the whole system shuts down as if somebody pulled the plug out, and then immediately restarts showing dialogue of whether I want to start windows normally or in the safe mode.

I have looked in the event logs but the only thing it tells me there is that there was an unexpected shutdown. The same in that reliability place.

Has anyone come across this, what could be the problem and how I would diagnose it? I cannot replicate it at will, as it only happens occasionally when scrolling, at other times scrolling is fine and does not produce this result.

Many thanks.

The system is Windows 7 enterprise 64bit, the mouse is Microsoft bluetrack technology

Are you able to try a different mouse with your system in order to ascertain whether the mouse is the culprit. If your problem persists with a different mouse, then we can rule that out.
