Had this PC for a year, recently ran into problems with it crashing whenever I play a game after 3 minutest I've got high end everything and was always able to play games for 8 hours and above and now 3 minutes into the same games it will crash, the pc won't crash but the monitor will go black then flash no signal... I've cleaned it out, cleaned all the dust, made sure all the fans are working and it still does this... I don't know why
