I have a GTX 750ti with a i3 4170 and 8bg of ram. Yesterday I tried playing Breath of the wild on the pc but I didnt realise how resource intensive it was untill I looked at my Task Manager and saw my ram was at 97%. I shutdown the game and decided to come off for today and play some other games tomorrow. I got on today and I went on destiny 2 which I usually run at 60fps constant and now its at 20fps and lower and im stuttering alot.

I hardware reset my computer just incase it was a memory leak but that did not help at all. I reinstalled my drivers (obviously) but still it did not help. I don't know if my ram is dying or its something to do with my gpu or what. Any help?
