My computer motherboard Gigabye 7nnxp would not boot with Seagate Baracude SATA drive any more. Nothing changed since last use. I tried all troubleshooting techniques and found no problem elsewhere. The SATA plastic cable has a crack on one end. When remove the power cable and SATA connector, the mobo will boot. As soon as the connector and power cord are connected. The computer just has front power switch light on, the computer won't boot. Does this mean the SATA drive is fried or I need to replace with new cables. I know the sATA cable is very flaky. Is this the source of the problem.
