I am going to recommend you go back to Windows 7. What I have realized over the past couple years since Windows 10 launched in 2015; anything pre-September 2013 doesn't work well with it.
Step 1: You need to download the install files for Windows 7 if you are reinstalling it on a system where it was previously installed. You can use the following resources:

Step 2: Make a bootable copy:

Step 3: Download any necessary drivers you might need for Windows 7 from the manufacturers website.
Step 4: Perform a custom install - see the Windows 7 section of the following article how to do that:

Step 5: how find your product key and reactivate:
Windows 7 came preinstalled on my computer, how do I find the product key?
The product key is usually located on the COA sticker attached to the bottom of your laptop or in the battery compartment. In some rare cases it can also be found in the memory compartment. For tower systems, look at the top or the side of the system unit. It looks like the following:
If the Certificate of Authenticity (COA) sticker is damaged or letters or not legible, you will have to consider the following options:
Use a digital camera to capture a picture of the COA then enlarge it on your computer.
If the COA sticker is damaged, then you would need to use the recovery partition to reinstall Windows 7, this will exempt the need to use the product key to activate your Windows 7 installation.
If your recovery partition is not available or damaged, you should contact the manufacturer http://www.google.com/url?sa=t&rct=j&q=... of your computer and request a recovery disc set you can use to reinstall Windows 7. They might charge a small shipping and handling fee. This will exempt the need to use the product key also.
I bought a retail box copy of Windows 7 or Windows 8 or Windows 8.1; where do I find the product key?
For Windows 7, the product key can be located on a pamphlet in inside the Windows 7 box.
