Today it was acting even weirder. I had the pc off for a while so as usual it made the sounds when I powered it on, but than next thing you know it went away on it's own after about 2 minutes.
Does anyone know what could be causing this? I tried vacuuming the back fan vent. It doesn't look SO dirty back there. Just normal dust build up... This thing is about a year old. I also looked back there to see if the fan wasn't spinning at anytime, and that's not the case because it seems to spin fine with and without the loud sounds.
