This is going to surprise A LOT of you…But one of the worst things you can do to your computer everyday is shut it down! Booting and rebooting your computer can really take a toll on it!
A few years back, an IT person at where I worked told me this, and I have to admit I was skeptical, but I am now a believer! We have officially had our E-Machine now for six years! YES, six years with no problems what so ever for this cheapie desktop we paid under $300 for. Sure we slow down a little here and there, but it tunes right back up without a problem!
So, stop shutting the poor little guy off at night and give him a break, you will use a little more electricity, but in the long run you will save more than buying a computer every couple of years!
