Microsoft's drivers are only the beginning so let's here more of the work you do after the OS install.
I have a Win 7 Home Premium 64 bit OS. It is installed on Samsung 840 EVO 120g SSD. 8g memory installed. CPU is AMD A8-5600K MB A55BM-Plus.
The computer ran find for several months. The other day I plugged my cell phone into the computer to take some pictures off of the phone. I have a Samsung Galaxy S4.
When I plugged the phone in, the computer it wanted to search for a driver. It didn't find one and immediately after that, the computer started to run slow. I'm talking so slow that it took several hours to boot.
So, I decided to do a fresh install, formatting the SSD, etc.
At this point, the install is finished. Restarting Windows is still extremely slow. This computer has 2 HD's on board. Is it possible that when the phone was searching for a driver, that some sort of virus was embedded on one of the drives? Or perhaps the SSD was corrupted to the point where even a fresh install wouldn't fix it?
I didn't format the drive and perhaps that is an option.
And who, it their right mind decided to make the key code on the label for Win 7 so small that I had to use a magnifying glass to see it?
