FX 9590, SABERTOOTH 990FX R2.0 1000w power supply - the pc wont boot - the fans spin up for a few seconds and then it shuts down. The Post State led for the CPU is on so i assume its the CPU overheating and then shutting done the pc. the odd thing is I have another rig with the same MB and CPU and it started doing exactly the same thing at the same time! Is it a CPU failure? is it solvable or do I just throw them away and buy some replacements??
