I got this Acer Aspire TC-230 around 2017 summer. In the past few years my PC has decreased gradually in performance for games, not being able to run games that I used to be able to run, not even being able to run that were said to be compatible with my specs.
This computer came with a 2.2Ghz AMD Quad-core & A8-7410 APU with R5 graphics.
Only recently I rechecked my radeon to find out that my core speed had decreased to 847Mhz.
I'm really unfamiliar with troubleshooting hardware related things as I just barely understand the architecture.
