Hi All.
I don't know if I should post this here or in General Help.

I just installed Win 7 Ult on a quad core machine. After a while, when the screen blanks, there's a lot of HDD activity (and associated noise, HDD light blaring, etc.) I can't tell what's happening because any activity stops it, and the screen re-appears as normal.

I'm new to Win 7, but when my XP idles it's as quiet as anything.

Does anyone have any ideas?

Thanks, Am.
