Here at “What’s On My PC”, since the beginning of time, I shut down all my computer’s at night. In the morning I power the computers back up and let the computers go into sleep mode during the day when not using the computers (if I am at home). If I leave home, I shut the computers down. I do all of the above for online security reasons, home safety reasons and I like the idea that every day the computers are being refreshed when starting up in the morning. Computers sort of have a mind of their own… If you click on the source link below, you will find a good read where various gamers tell you their thinking on this.
Depending who you ask, turning off your PC at night is either a good way to save electricity or a good way to speed up the deterioration of your hardware. Or maybe it’ll help prevent the build-up of dust. Or maybe powering down and then up again uses more electricity than just leaving it to hibernate would. Or maybe the RGB gremlins will get sad if you don’t leave a light on for them. At this point there’s so much conflicting advice, it’s tempting to just throw up your hands and stop caring.
