So, my knowledge on computers is very limited so if someone knows a fix on this problem, please let me know. I was playing a game on my computer with Spotify playing, when all of a sudden it froze, and I let it sit there like before (PS this isn't the first time it did this), usually I do this and It takes me back to the lock screen and everything was fixed after that, but this time it sat there for 10 mins, and it took me to the lock screen, but when I loaded up the game I was playing before it crashed, and this time my frames sucked, everything was lagging and I wasn't able to hear the audio. So, I went to watch YouTube to see if it was only the game but no it wasn't, the video was lagging and I dont know what to do. Can anybody help me fix this or at least know the problem, please and thank you.
