Neighbor threw away a his old macpro 1,1, hasnt been turned on since about 2016 (6 years), i got it, plugged it in turned right on, used it for about 30 mins, turned it off, went back to it about 20 mins later, nothing, just 2 red lights that say cpu a+ b overheat, its been 2 days, still doing the same thing. Psu i tested and its good, took out the gpu, swapped ram boards with another macpro, still doing the same thing. Anyone know?
Did you replace the PRAM battery and check the CPU’s (apply fresh TIM and make sure the coolant hadn’t leaked out of the heat sink)
