So I'm not sure if this is the cause of my hard freezes but I've tried EVERYTHING too get my computer to stop freezing... what happens is I'll be casually browsing my desktop or internet browser and it'll just freeze up on me! The sound will stutter and I can't get anything to respond unless I shut it down via the power supply or unplug the computer entirely. I'd also like too note that this never happens when I'm playing a game or anything that requires full screen. I've already ran memtest86 overnight and have received no errors. I've also made sure nothing was wrong on the motherboard or power supply by checking the capacitors. It just baffles me and I don't know why this is happening... these freezes happen at random as well.. but once again will only happen if I'm on my desktop or on Firefox. I've also switched breakers to my computers outlets to make sure it wasn't that.
