How often do you power down?

I tend to leave all my PC's running 24/7 except for reboots on new installs. I power down the monitors at night while sleeping. Only completely shut off when needed, like for adding new parts, etc

Depend what i'm doing, voted daily basis, but it could two days because when i'm on uTorrent for Live Gigs only, it cannot turn on to sleep mode. So guess every two days!

I power mine up only when I use it (which is most of the time) and power down when I'm finished with whatever I'm doing, but sometimes I hibernate it (if I have lots of stuff open and am lazy to save them or want to continue later)

I leave my server on 24x7...but all of my desktops get shut off if I am not going to use them for a couple of hours. These machines just suck up quite a bit of power these days with high end cards and such that leaving them always on is just wasting money in my opinion.

I pay attention to my ram usage. At first boot it's usually at about 19% at idle. When it gets to 30%+, I usually power down. Pretty much just a quirk that I've carried over from Windows 95.

I use sleep exclusively when away from it for any length of time. I also turn off the monitors because of the horror stores I've read about monitor files. I'd rather do something that may not be necessary than to wish I had.

I power down generally once a week, but I use sleep mode if I'm going to be away form the computer for more than a half hour.

I pretty much operate like Cato. I watch my ram usage and reboot accordingly some times. Once in a while I reboot because something is not working quite right (not a common occurence). I use sleep mode because I have had some problems with hibernate.
