Strife-worn Computers!

My fav old (2 years) computer is acting up again. I have a hunch she's simply worn out from fending off viruses and other attacks, second by second. I've now switched to another primary computer—and all is Sweet for the moment. So much shit attacks these poor babies that eventually, like the human body, they just give up the ghost.

Any techies out there who want to confirm or refute this layman's assessment?

(I'm always sad to lose a good friend, even if she can do no more than think fast in 1s and 0s!)
