should i leave my computer on all day or?

I say keep it on all day, turning it off and on constantly is harder on the computer than if you just kept it on. I say keep the modem on too.

If you don't like restarting and waiting for everything to load, then you can put it on sleep mode. All you have to do then is hit the mouse or keyboard and it will go on where you last left off at. Sleep mode turns your computer off basically, without having to restart the whole thing. It saves you a lot on your energy bill instead of leaving it on all the time = D

Quite frankly it all depends on how often you are using your PC. I leave mine on all the time but I am using my PC on and off most of the day and night. As for the modem they were built to stay on.

If you are busy w/PC and want your alerts -- leave it on and you can see it all if not , you check every so often turn it off-same w/modem, I game so I leave mine on-and bet IMs form buds so I can answer them faster hehe

i only turn mine off when its raining hard

other than that, it stays on
