So my mother handed me down maybe a year ago an MSI GT 783, Intel Core i7-2670QM with nvidia gtx 580m. Few months ago the computer begin to shut off every few seconds when playing a game and every few minutes when I was just on my internet browser up to the point that now when it turns on the touch buttons like the turbo bright bluetooth and wifi and disc eject don't light up and neither does the keyboard the monitor doesn't turn on and I plugged it into my hdmi t.v and got nothing. Aslo when I turn it on the fan goes into automatic full speed and just says at that speed untill i power it down.
