I'm fairly new to gaming PCs and have owned this one for about four years, upgrading several parts along the way. Lately, downloads are much slower than expected, and games become nearly unplayable when I use high graphics settings. My current hardware includes a B450M Pro4 R2.0 motherboard, an AMD Ryzen 5 5500 processor, an ASUS GeForce RTX 3060 with 8GB of GDDR6 memory, 32GB of Corsair Vengeance RGB Pro DDR4 RAM, and a Thermaltake Smart 700W 80+ power supply. My storage devices show up as an Apple HDD and a Team T253A3512G drive. What should I check or upgrade first? I'm also open to reliable programs that could help diagnose or improve performance.

For the game problems, update the RTX 3060 drivers and monitor temperatures and clock speeds with a tool such as MSI Afterburner. If the GPU or CPU is overheating, it may throttle and lose performance. Also check Windows startup programs, scan for malware, and use a high-performance power plan while testing. If software checks do not help, back up your files and consider a clean Windows installation, followed by motherboard BIOS and driver updates.
Download speed usually comes from your internet connection and network setup, not from the graphics card or processor. Test with Ethernet if possible, check your internet plan, and make sure Wi-Fi antennas are connected if you use wireless. A faulty network adapter or cable is also possible, but the network connection should be tested before replacing PC parts.
The storage setup may be a major part of the problem. If Windows or your games are running from the hard drive, loading and general responsiveness will be much slower than with an SSD. Install Windows and frequently played games on the Team drive if it is an SSD, and check that it has enough free space. For gaming performance, also confirm that your monitor cable is plugged into the RTX 3060 rather than the motherboard’s video output.
Thanks for explaining that. I’m not very familiar with diagnosing hardware, so I’ll check which drive Windows and my games are using first.

The full diagnosis also depends on the exact storage drive, temperatures, game resolution, and frame-rate expectations. The Ryzen 5 5500 and RTX 3060 should handle many games well at 1080p, but demanding newer titles may require reduced settings rather than maximum graphics.
