I started building a new system last night, and had it working for probably 30 minutes or so, and was working through the BIOS to setup RAID. During one of the resets, however, the PC wouldn't start up again. More specifically, what I did during that reset was add a power cable to each SATA drive, rather than having them hooked up on the same power cable. After the startup, pushing the power button the case did nothing. No fans started up, no LEDs lit up. Nothing. I stripped everything, minus the motherboard, PSU, and RAM, just to be sure nothing was interefering with anything else. Also double-checked that all the case wires were plugged in correctly. Still nothing. This was all last night. This morning, I was jiggling some cables to try to get something, when I noticed that if I pulled the main 24-pin power cable out of its seat just a little bit, the PSU fan would start up, and the case's power LED would light up. The CPU fan didn't start, though. And if I plug in a case fan, that will start up, as well. But as soon as I fully seat that 24-pin again, everything shuts off. So I figure it's a problem with one of three things: the PSU, the motherboard, or possibly the case power button. Does this behavior sound familiar to anyone?
