Hard Drive Life Expectancy
I couldn't find too much info on Google and was wondering, what is the life expectancy of most hard drives? I'm specifically worried about my 5 year old HDDs that are in my computer right now. I only back them up around once a month, and would be really bummed if one of them died after a few weeks without a backup.
Also, what is the lifetime of video cards? Mine has developed a grinding hum that comes and goes. Sometimes I'll hear it for up to a week and sometimes only for a few minutes, but it drives me crazy! I really just want an excuse to buy a new computer, but this one still works so I can't justify it yet.
