Just ordered a new PC and was just thinking that when it comes I'm going to be really good and do things like regularly clean out the dust and maybe even turn it off every night... before wondering how long that would last. My old PC died at the end of last year after five years of reliable service... and i mean five years. I'd reboot every month or so and i reckon the longest it's been off for is a week, and the second longest, maybe overnight once or twice. I never even think of turning it off until it gets a bit sluggish, or crashes... but is it just me? I've been using a laptop for the last 6 months and at first, i turned it of every night but that soon became hardly ever too does anyone else hardly ever turn their PC off?
