What to Do After Building a PC: BIOS, Windows and Drivers

1. Record the first BIOS baseline

Open the BIOS using the key named in the motherboard manual. Compare its CPU name, memory capacity and drive list with what you installed. If you fitted two memory modules but see only one module's capacity, fix that before installing Windows. Check the CPU temperature and the fan or pump readings expected for your cooler. A rapidly climbing temperature is a reason to shut down and inspect cooling, not to move on to a benchmark. Take a photo of the BIOS version and hardware summary; keep CPU tuning and XMP or EXPO disabled for now.

2. Review firmware updates deliberately

Find the support page for your exact motherboard, including its hardware revision. Compare the installed BIOS with the version required for your CPU, then read the update's release notes and security notices. If an update is needed, use that board's file, filename, USB preparation and update procedure. Let its restart sequence finish without interrupting power. With a reused encrypted drive, save the recovery key and follow the encryption precautions before updating. Afterwards, reopen the BIOS and check the settings again; an update may have reset them.

3. Check Windows 11 eligibility and prepare media

For Windows 11, check Microsoft's requirements against the complete build, including the supported CPU, UEFI with Secure Boot capability and TPM 2.0. A TPM warning calls for checking the board's firmware TPM instructions; clearing it is not a routine installation step. Use Microsoft's download page to create installation media on an empty USB drive. Have the motherboard's network driver available separately if needed. Windows 11 Home and Pro for personal use require internet access and a Microsoft account during initial setup, so prepare these before starting.

4. Install on the intended drive

Select the official installer from the board's boot menu in UEFI mode. At the disk-selection screen, stop long enough to identify the intended drive by model and capacity. Back up any data you want to keep before deleting partitions. If several drives make the choice confusing, shut down and disconnect the unrelated drives before continuing. Follow the prompts for the Windows edition and licence you own. If no drive appears, check the board's storage-controller setup and driver instructions. Randomly switching RAID settings can create another problem on an existing installation.

5. Add the correct updates and drivers

Once the desktop loads, install Windows updates and the drivers for the motherboard, network hardware and graphics card. Use the exact model's support page and select the correct operating system. If using an AMD chipset package, check its supported-chipset list. Restart when prompted, then test the device you just installed: network access after a network driver, audio after the audio driver, and display output after the graphics driver. Leave lighting suites and other optional utilities until these basics work. Avoid driver bundles that change several unknown packages at once.

6. Confirm everyday operation and protect recovery access

Set the display to its intended resolution and refresh rate, then check memory capacity and available storage in Windows. Plug a known working device into the front USB ports and try your headphones, microphone and network connection. Check activation and save any device-encryption recovery key somewhere accessible without this PC. Keep the parts list, BIOS version and essential driver downloads together. If the machine later needs recovery, you should not have to open the case to discover which network adapter or motherboard you bought.

7. Test before optional tuning

Use the stability guide below once ordinary use is working. Enable an XMP or EXPO profile only after those checks, and test it as a separate change: both are memory overclocking settings. If crashes start after the profile is enabled, restore the previous settings and repeat the task that failed. Know the board's recovery procedure before making changes that might prevent startup. A BIOS update, memory profile and CPU adjustment made together leave you with three suspects; doing them separately gives you a useful answer when something fails.

Your checklist

• The BIOS shows the installed CPU, full memory capacity and intended system drive.
• The CPU cooler is working before any sustained load test.
• Windows and the essential drivers are installed, with activation checked.
• Display settings, network, audio and front ports have been tried.
• Recovery keys and the working BIOS settings are saved before tuning.
