Laptop Over Heating

Well, I’ve spent the whole entire night fixing my mom’s laptop. Running diagnostics because the laptop lost it’s ability to enter into the windows program. Finally after many attempts via the BIOS settings, I was able to re-enter into windows normally. The operating system shut off because of CPU and Mother Board over heating. As a physical inspection confirmed as well, the fan is dirty and I need to clean it as well and add thermal paste to the cpu. The laptop is finally back in service. Just a few more steps and it is complete.
