Hello early this year I upgraded from an Radeon hd 6450 to a R9 270x. I have an fx 6300 six core processor clocked at 3.5 ghz. My power supply is a turbo link 500w psu. Now I have been having the problem where when I am gaming my computer randomly shuts down and the power on button on the front flashes green all I have to do is turn it off and turn it back on to stop that. But I have had to lower the amount of speed my cores are at to stop this issue from happening and it still happens even at rather low speed sometimes. Now I think it's the power supply that is the problem but I am not to sure. That is why I need help from people who know what they are talking about. I am tired of not being able to have my pc game at it's max performance and causing me to get lower fps than I should be. Any information would help.
