I acquired a Gauntlet Legends and it played fine for a week or so and now it will reset while playing. When I say reset, I mean like someone pulls the power and plugs it back in. It looks like the power supply has been changed out before. Also, I have ran a self test on the board and everything appears fine. I have through;y cleaned the inside of dust and made sure they fans are working properly. Has anyone had this issue or have any idea of what might be going on? Thank you.
