It depends on how you use your computer and how well you maintain it. I have a number of computers that are still going on strong after more than 10 years doing things (now they're mostly file servers or audio streamers but still fully functional). Except for checking for patches and ensuring a monthly reboot (Windows) they're still going on strong.
