What controls and makes r760 burn out I've replace parts q708,q703,z705,z702,r760,r765,and a few more got the monitor up runs for a few min. R so it's like when it starts I get good b+ then it's like something kicks in and b+ goes up then blows hot and r760 burns when i check tp106 its like its got a heart beat? Ive tested the power supply with the light bulb trick its fine its had the updates where do I need to look?
