System has been working for 14 months now. Recent problem. System is MSI K8N Neo4 Platinum SLI motherboard, Antec SP-500 powersupply, Extreme AX850 graphics board. System started by not booting at all not even fan power. So I jumpered the green and black to the motherboard from the powersupply and fan turns. Push button on front of cabinet is that still a factor? Machine won't boot and or is some time intermittent at booting all the way up.Thinking that it still could be the switch or wires to the motherboard if this is still a factor or maybe problems with the motherboard, history.
