Mini Project — Part 3: OS Setup, Verification, and Final Wrap-up

Let's think about this for a second

Since Part 2 got you to the POST screen, now you'll follow the OS, Drivers, and Final Checklist chapters to take the PC all the way to an actually usable state. The goal of this stage is to connect the hardware assembly to the software layer and verify stability/performance. The success criteria for the whole project isn't just "it boots" — it's reaching the level where temperature, stability, and every driver are all correct. Once that's done, the project is complete: a reliable PC ready for daily office/home use.

Let's build it for real

Boot from a USB installer (Windows 11 or a Linux distro) and install the OS onto the NVMe SSD. Once installed, download the motherboard's chipset driver and LAN driver from the manufacturer's website and install them (if you're using an iGPU, include the graphics driver too). Run Windows Update / your package manager's update to bring the system fully up to date. Use a tool like CPU-Z or HWMonitor to check idle temperature and confirm it's around 40-50°C, then run a short stress test and confirm the temperature doesn't go past 80°C. Finally, go through the Final Checklist — cable management, dust filter, BIOS date/time correct — review everything, and close out the project.

OS installed and chipset/LAN/graphics drivers all updated
Measured idle and stress-test temperatures with a tool and confirmed they're within an acceptable range
Reviewed the entire Final Checklist (cable management, BIOS setting, dust filter)

FINAL VERIFICATION (Part 3)
----------------------------
[ ] OS installed on NVMe SSD
[ ] Chipset driver installed
[ ] LAN driver installed
[ ] Graphics (iGPU) driver installed
[ ] Windows/package updates applied
[ ] Idle temp checked (target: 40-50C)
[ ] Stress test run (target: stays under 80C)
[ ] Cable management tidy
[ ] BIOS date/time correct
[ ] Dust filters clean / in place

STATUS: Project complete when all boxes checked.

You should see

You'll finish a daily-use-ready Budget PC project — OS, drivers, and updates all done, with temperatures holding stable under a stress test.

5-Minute Try-It

Open Task Manager (or System Monitor), watch idle-state RAM usage and CPU usage % for about 5 minutes, and note which background processes are using the most.

A Quick Word of Caution

Before you install drivers, Windows Update may already have auto-installed a generic driver — check Device Manager for a yellow warning icon first.
