No CPU, sorry. But part of the nVidia-Chipset: NVIDIA nForce System Management Controller->PCI\VEN_10DE&DEV_0AA3 Install the last nVidia-chipset-drivers for your laptop.
Try this go to said device in device manager and uninstall it once you done reboot PC and see what happens.
I slapped myself across the face. When I read Obama's reply, I realised that I had indeed forgotten to download the chipset drivers... I took the drivers from ASUS's website and now the Device Manager lists my hardware correctly. Much obliged, people!
