Win 7 Screensaver

[nevica]

Hello,

I am running Win 7 Home Edition.

I am having trouble with the screensaver and sleep mode. I find that it works OK a few times after switch on but stops working after about 4 times.

This must mean that something is running in the background. As yet I have found nothing obvious. This is a new install of Win 7 so no other programs have been added.

Any idea what could vbe the problem and how I can solve this?
