What is Gallium?

Gallium: finally understand your PC

Is your PC slow, crashing or blue-screening, and you don’t know why? Gallium checks your machine in 30 seconds and clearly tells you what’s fine, what to watch and what’s failing, with the steps to fix it.

🩺 Real diagnostics, component by component. CPU, graphics card, RAM, every drive (SMART status), battery, network, drivers and Windows security. Unexpected shutdowns and blue screens are explained, along with the component most likely at fault.

🧪 Tests to be sure. CPU stability test, graphics card test, RAM check without restarting or the full Windows memory test. Perfect after a clean-up, a hardware change or buying a used PC.

⚡ Risk-free optimizations. Power plan, Game Mode, mouse acceleration, temporary files… Every tweak is one click to apply and one click to undo, and a restore point is created automatically.

📊 What your PC is worth. A score for every component, estimated FPS in about thirty games, and a database of 470 CPUs and 300 GPUs to compare or plan an upgrade.

🛠️ Built for repair shops too. Professional mode adds PDF reports for your clients (serial number, diagnostics, tests, before / after), client records with multi-PC history, and a detailed driver list.

🔒 Privacy first. Gallium runs entirely on your PC: no account, no ads, no data sent.

Windows 10 and 11 · 20 languages · installer or portable version · free and open source (GPL-3.0). If Gallium helps you, you can support its development on Ko-fi ☕
