Back up your files first, remember during the booted install to delete all partitions down to Unallocated Space, then click Next to auto-create and -format the needed partitions and begin - this makes it foolproof.
After install expedite Windows Updates until no more are offered, then import drivers from the manufacturer's Support Downloads web page for your exact model. While there make sure that you also have the latest chipset, BIOS, display, network, bluetooth, USB and all other drivers, compared to the ones presently installed in Device Manager reached by right clicking the Start button.
Keep me posted on your progress as I will be here to help until the case is resolved.
