Would you be surprised if I told you computers don't last forever? Probably not. The big question is what you should do if your beloved 7-year-old computer is on its last legs.
The bottom line is you shouldn't bother fixing it. The average lifespan of a computer is 4 to 6 years. Computer gurus upgrade or replace their computers every other year or so.
That's because technology moves at a fast clip. The high-end computers of today are the budget PCs of tomorrow. You really don't need to spend much to get a new, usable machine. But if you're ready to splurge, you can get a system unbelievably faster than your old one.
