In the last 9 years, my gaming PC didn't always have top-tier hardware, but it wasn't plagued with major bottlenecks either. Whether it was my Ryzen 5 1600 and GTX 1660 Ti budget build or the current Ryzen 7 5700X and RTX 3080 rig, I've enjoyed whatever game I've played on it. The real bottlenecks on my PC have existed in the form of high CPU temperatures, Ethernet slowdowns, frequent Windows corruption, and anomalous sleep behavior.
Partly due to procrastination and partly because I ran out of ideas, I struggled with these issues far longer than I needed to. In the last few months, however, I managed to weed out each one of these issues from my PC for good. And the best part is that I didn't have to spend a single penny doing it.
