My sims computer was built in 2012, it's had some new hard drives but that's about it! It's a legend in my house.

My laptops have mostly reached around 5-7 years old, and the desktop one did started failing after around 8-ish years, but they've all been heavily used and travelled with (even the desktop one, which had to endure some rounds - quite well packed, as I kept the original box and all for that purpose. The screen cables got the worst of it, so I always had to adjust away the ghost images )

EDIT: Seems the issue I had with the laptop was fixable, and it also got a cleaning job while they were at it, so hopefully it lasts for a bit longer . It had its first trip outside the house in a somewhat improvised backpack setup (can't find a cover for the thing, too big) and the weather was kinda iffy, so I was just hoping it wouldn't rain (just a few drops, nothing got wet).
