Alright so I was just browsing YouTube when all of a sudden my PC shut down. When it rebooted itself (I didn't touch anything) only one of my front, LED fans were on, and I have two. I restarted manually and it all works fine but I'm wondering why this happened. Also when I tried to turn my PC on this morning 3-4 times it got stock on the bios screen? Any ideas. I know it wasn't my ram getting maxed I have 16 gigs. Please help!
