I just got a new PC and I wanted to know what is the best way to keep it lasting for many years. Should I use the standby mode or the turn off mode if I'm going to be away and not use the computer for more than 12 hours. When I used the standby mode I can still hear the fan running on the PC so I'm concerned that running it all the time like this will cause the part to fail prematurely. But I also read that shutting down your computer and restarting it causes more things to fail than using the standby mode. Once again this is for being away for 12 hours or more a day. Thanks.
