Hi:

See if you can clean install W8.1 by using the W8 SL key in your PC's BIOS.

Install W8.1 by creating the Microsoft installation media, using another Windows PC, if yours is not working...You want W8.1 Single Language 64 bit.

Only if you are asked to enter a product key during the installation process, use this generic key.

This is the generic key for W8.1 Single Language

Y9NXP-XT8MV-PT9TG-97CT3-9D6TC

If you had to enter the generic key, manually change the generic product key to the W8 Single Lanugage key in your PC's BIOS in the PC settings menu.

After you get W8.1 installed, and you had to manually enter the W8.1 generic product key, you will need to run the free utility I zipped up and attached below, that will show you show the W8 product key in your PC's BIOS.

I have also zipped up and attached below, the Microsoft tool which hopefully will transfer the ISO file to a DVD or usb flash drive so it is bootable.

Then you can install the available drivers and software from your PC's support page.
