Your computer’s BIOS is like its brain’s foundation — it’s the first software that runs when you turn on your PC, initializing the hardware and starting Windows. But did you know that updating your BIOS can improve system stability, hardware compatibility, and even performance?
If you’ve ever wondered how to update BIOS on Windows 10, this guide will walk you through every step — safely and confidently.
We’ll explain what BIOS is, why you should (or shouldn’t) update it, and the best ways to perform a BIOS update without risking your system.
What Is BIOS in Windows 10?
BIOS stands for Basic Input/Output System — the firmware that boots your computer and connects the hardware with your operating system.
When you press the power button, BIOS:
-
Performs hardware checks (POST – Power-On Self-Test)
-
Initializes components (RAM, CPU, storage, GPU)
-
Loads the bootloader to start Windows
Modern PCs often use UEFI (Unified Extensible Firmware Interface) — an advanced version of BIOS with a user-friendly interface, faster booting, and secure boot options.
⚙️ What Does Updating BIOS Do?
A BIOS update can fix bugs, improve stability, and enhance hardware support.
Here’s what a BIOS update might include:
| Benefit | Description |
|---|---|
| Hardware compatibility | Supports new CPUs, GPUs, or RAM |
| Bug fixes | Resolves system crashes or boot issues |
| Performance improvements | Optimizes boot speed and system efficiency |
| Security patches | Fixes BIOS-level vulnerabilities |
| Feature upgrades | Adds new BIOS or UEFI options |
💡 Example: If you install a new AMD or Intel processor and your PC doesn’t start — a BIOS update often fixes that.
⚖️ Should You Update BIOS? (Pros & Cons)
Before you rush to update, know that BIOS updates are not like normal software updates — they carry more risk.
✅ Pros
