Had issues with loud noises and over heating/ pc not shutting off or on and taking HOURSSSS to reboot,and went to repair to manufacturer ( ty GOD for 2 yr full warranty) 4 times til they finally got it right!!!did alot of switching out of motherboards/fans/cpu fans etc turned out to be a serious cooling issue on both the motherboard and the cooling fan and cpu fan......now for the past 7 months not a problem!!! I am using now and for ever will use a cooler fan a heavy duty one since my laptop is 17inches and a dual core amd.
well at the moment everything is fine, and it only seems to do this like once a month over the past 4-5 months. If it happens again I'll post something.
Occasionally my laptop will make this horrendous ass loud whirring noise, as soon as I reboot it though it goes away. I suspect it would be the fan, but my fan still runs fine. It'll just randomly decide to go apeshit and as soon as I reboot it runs normal.
