I am having issues using two monitors coming off my L5 via DVI, I recently upgrade my L5 from vista 2 to Vista 3 and ever time I attempt to use the two monitors it completely freezes and I have no control what so ever. I have to hard power off just to get it working again.
That sounds like a potential issue with your Windows installation.
The forum is the wrong place to troubleshoot things like this.
