Ok, so this is a relatively new thing with my pc, just started in the past week or so but tonight it's happened twice within a couple hours. Basically my pc works fine and then it will randomly freeze up. My mouse during this will progressively get slower for about 2-3 seconds till the freeze actually happens and then nothing works on my pc till I hold the power button down till it shuts off. Also, one time it happened when I was watching a friend streaming and the sound got really warped as well and when it froze it just kept the same tone. I'm not entirely sure what it could be. Any suggestions/help would be much appreciated!
