Have you disabled windows screensaver\power options

Welcome to MP

Sorry I'm new to this and did not finish my question. I meant to add that i have an HP pavillion 6000dv series laptop with an NVIDA GeForce 84oo card and running under Vista Premium. As I started to say, after about 10 mins or so, the screen blacks out and I get some clicking noises and all I have to do to stop the clicking and bring the picture back is move the mouse. But that's annoying

I have tried changing and disabling my Screensaver settings with no effect. I read somewhere that I might have to disable UAC which I'll try and I'll also try changing my power off settings

OK, looks like the problem was my power off settings, I generally watch videos in battery only mode and it was set to power off after 10 mins in battery mode
