I realize this is a small issue but my screen saver or "sleep" mode will not come on. Although I don't know if it's related, but I recently installed a Microsoft Laser 6000 mouse - ever since then the sreen saver won't come on AND it won't gone into dark screen/sleep mode. I have to turn off the monitor when not in use.

If it's only been since installing that mouse, it's safe to assume the drivers for it are the culprit. Try reinstalling your graphics drivers.
