So, i built my first pc. It was wonderful, an i5-6400, GTX-1060, 8gb of RAM and 2tb of hdd. But my dog managed to knock it off my desk while i was away. Now I'm having problems doing anything. It completely boots up, but the disk usage is always jumping all over the place. I also cant play any games. My fps on CSGO went from 300 to a steady 20 that jumps to 100, just to go all the way back down. I cant tell what the problem is, i do heavily believe its related to the hdd. But i figured id ask you guys what you think.
