I installed Motherboard Drivers from the Foxconn page
Also, I installed On-board Lan and Vga drivers from the same page, but Audio Drivers Installation could not be completed.
I uninstalled Turbo boost, but I could not find any Mpksl devices in Device manager.
Slimdrivers says that all my drivers are updated.
