So i just reccently upgraded my PC from a FX-6300 with a gb of ddr3 , to a Ryzen 5 1600 with 8gb of 2133 ddr4 and i also added a SSD to my system but ever since my PC has been EXTREMELY slow at opening applications, new chrome tabs and games even when they are located on the SSD and when i go to try to play Battlefield 1 the game frezzes up my entire PC and i have to restart it and when i play one of my favorite games, War Thunder when im in the game the game will freeze up for up to 15-20 seconds. I'm super confused as to why this is happening to my pc and i have no clue how to fix it or what is causing it, now i am running Windows 10 but since i buy my keys from a site called kinguin i have to buy a new key every time i upgrade so my Windows isn't activated but i highly doubt that that is causing this slowdown and i haven't bought one yet because im looking to upgrade from my GTX 1050. Any help is much appreciated.
