01.Why Monitor Your PC?
In 2026, with processors using automatic boosts based on temperature, not knowing how your hardware is performing is a mistake. Monitoring allows you to identify bottlenecks (CPU at 100% and GPU at 40%), overheating before the PC shuts down, and even voltage issues in the PSU that could fry your components. Knowledge is power for any PC enthusiast.
Don't do it Manually.

02.1. MSI Afterburner: The King of Frames
Indispensable for any gamer who wants to see data while playing:
- On-Screen Display (OSD): Places an FPS and frametime graph in the corner of your screen without needing to exit the game.
- Versatility: Works with graphics cards of all brands (NVIDIA, AMD, Intel).
- Thermal Throttling Check: Lets you see if the GPU clock drops when it hits 83ºC.
03.2. HWiNFO64: The Sensor Bible
Professional Information:
If Afterburner shows you the basics, HWiNFO64 shows you everything.
It reads sensors that other programs ignore, such as memory module (VRAM) temperatures, exact fan rotation speeds, and even if your motherboard is delivering the correct power. In 2026, it is the #1 tool for diagnosing blue screens and unstable hardware issues.
04.3. Tip: Xbox Game Bar (Win + G)
Don't want to install anything?
Windows 11 has a lightweight native monitor. Just press Win + G and open the 'Performance' widget. It shows CPU, GPU, VRAM, RAM, and FPS usage in a simple and discrete way. It's ideal for those who don't want screens full of numbers and graphs but want to have an idea of what's straining the PC.
