Post-Installation Fixes: Troubleshooting Your Fresh PC Build

Congratulations on finishing your build! However, sometimes a fresh installation can throw unexpected errors—from missing drivers to system verification issues. Don’t panic. Most post-installation problems are common and can be fixed in a few minutes. This guide covers the most frequent ‘Day 1’ issues and how to resolve them like a pro.

Resolving System Verification Errors

If you see an ‘Activation Failed’ message or a watermark, try these steps first:

Check Internet Connection: Windows needs to communicate with servers to verify your hardware-linked setup.
Error 0xc004c008: This often happens if the hardware signature isn’t picked up instantly. Use the ‘Troubleshoot’ button under Settings > Activation.
Bundle Support: If you are using a [PCBuilderKeys Bundle], ensure you have entered the setup support code exactly as provided in your delivery email.

Fixing Driver & Hardware Issues

Is your mouse lagging or is the screen flickering? It’s likely a driver conflict.

Graphics Drivers: Download the official installer for your GPU (NVIDIA/AMD) instead of relying on Windows Update.
Peripheral Mapping: If your mechanical keyboard isn’t responding correctly, try a different USB 3.0 port.
Unknown Devices: Open Device Manager. Any item with a yellow exclamation mark ⚠️ needs a driver update from the motherboard manufacturer’s website.

Performance & Stability Fixes

If your system feels sluggish after the first boot:

RAM Frequency: Check your BIOS to ensure XMP or DOCP is enabled so your RAM runs at its rated speed.
Windows Updates: Run Windows Update multiple times until it says ‘You’re up to date.’ Many system files are updated in waves.
Power Throttling: Ensure your PC is set to ‘Best Performance’ mode in system settings.
