I have changed my hard disk drive to SSD and upgraded my RAM from 4GB to 12 GB. Before that, i can run league of legends with a stable 120 FPS but after that changes my league's FPS fluctuates so much. It goes from 20 FPS to 120FPS+ and then drops back to 20FPS + and the cycles keep on repeating. Anyone has any idea on this? I have provided my GPU/CPU and FPS chart in the link below.

After changing the SSD, i have fully installed a new window and didnt perfrom any updates yet ( im not sure if this related to any outdated drivers)
