Re: Do you keep your PC on 24/7 ?
I shut my stuff down every night unless I need something to run through the night when it will not bother me (like downloading games on Steam under Wine really saps my internet speed unless I run it at night).
I prefer the savings and thunder storms are becoming increasingly common where I live, and have lost several hundred dollars in networking equipment because of it-I don't want a repeat of that for more expensive computers.
Backups are amazing. 99% of data loss can be prevented by spending less than $100 on an external drive.
If you have seen an error, there is a good chance someone else has, too. Google is your friend.
