I've had my gaming PC for about five years now, and aside from the fans, everything else is solid state, so there's no mechanical wear and tear. I'm wondering if, after all this time, the performance has dropped because of actual hardware degradation or if it's just a perception influenced by things like software bloat, dust buildup, or corrupt operating system files. If I cleaned it out, applied new thermal paste, and did a fresh Windows install, could I expect it to run as well as when I first bought it?

There are definitely minor degradations in performance due to overheating and dust buildup, but typically if everything is running cool and clean, you shouldn't see much decline. The biggest issues usually come from how software is running on your system.
It's likely not the hardware degrading, but more about how software evolves. Games often receive updates that can make them more demanding. For instance, Fortnite now takes more resources to run compared to five years ago.
Many people overlook the fact that slight degradation is possible—especially if you've overclocked your components. But honestly, if you keep up with maintenance, your PC should still feel pretty snappy. It's usually the software that demands more over time.
In terms of raw performance, your PC's components won't really degrade over time. If you perform upkeep, like replacing thermal paste and keeping things clean, you should see similar performance. However, modern games can require more power, which may give the impression that your system is slowing down.
A lot of the slowdown can come from how bloated the OS and applications become over time. Regular cleaning and a fresh OS install can really help—I've noticed a significant difference after doing so!
Totally agree! Cleaning dust can help so much. I typically do a format every couple of years to keep things running smoothly.

Exactly! It's often software bloat and updates that add more content and requirements, not a drop in hardware capabilities.
