So I built a new computer a few days ago, and when I went to turn it on for the first time it powered on for a split second, then I couldn't get it to turn on again. I rebuilt it from square one with only the essentials. It booted no problem. When it came down to the hard drive however.. it did the power thing again. I tried replacing both the power and the sata cables but nothing is changing. My main pc has a hot swap drive bay so i popped out my drive from that one to test it and it did the same thing. So now I have another issue. I popped my drive back into my main pc after that test... and now my main pc wont power on unless my HDD isn't plugged in. Any ideas here? I'm getting kinda frustrated...
