I'm moving to PC gaming after more than 20 years with consoles. I'll still keep a PS5 Pro, but I'm interested in the wider range of visual-quality and performance options that a PC can provide. I'm not very technically experienced, so I'd like practical, beginner-friendly advice that won't compromise system stability or hardware safety. The system uses a Ryzen 7 9850X3D, GeForce RTX 5090, ASUS TUF Gaming X870-Plus WiFi motherboard, 64GB of DDR5-6000 CL30 memory, a 2TB Samsung 990 NVMe SSD, a 360mm liquid cooler, a 1200W power supply, and a Lian Li Lancool 217 case. I already know about enabling Resizable BAR in the BIOS. What five BIOS, Windows, cooling, or power-related changes would you recommend for improving gaming performance and reliability?

Check the case and radiator fan directions. You generally want a clear path for cool air to enter and warm air to leave, with sensible front-to-back or bottom-to-top airflow. Verify that the pump and fans are detected, set reasonable fan curves, and monitor CPU and GPU temperatures while gaming before attempting any overclocking.
Enable the memory profile in the BIOS—called EXPO on an AMD system—so the RAM runs at its advertised speed instead of a slower default setting. After enabling it, confirm in the BIOS or Windows that the memory is actually running around DDR5-6000. If the system becomes unstable, revert the setting or use a slightly lower speed.
Make sure the BIOS, chipset drivers, graphics drivers, and Windows are reasonably up to date. Also install the motherboard manufacturer’s chipset and networking drivers rather than relying entirely on generic Windows drivers. Once the PC is stable, avoid changing several settings at once; that makes troubleshooting much easier.
A UPS is useful if your area has outages or unreliable power, though it’s mainly for protection and graceful shutdown rather than extra gaming performance. I’d also consider a clean Windows installation if the store installed lots of unwanted software, then remove unnecessary startup programs and check that games are using the dedicated GPU.
