Hello, I am unsure if this is a motherboard problem. I was installing a usb header. When I try to power it up, there is a flash of power (all indicator lights on the motherboard turn on), then turns off. I took out the bios battery, waited for an hour then put the battery back in. The lights all come back up for a few seconds, then I think before it starts to post it shuts off. Subsequent presses will make the lights flash, but everything goes out again.
I removed everything including the cpu now, and the only things connected to the motherboard is the two power cables. I wanted to see if the motherboard will at least stay on and give me a error message, but it will do the same thing. Removing the battery, waiting for an hour then putting the battery back in and powering it on will have all the motherboard indicator lights come back on for a few seconds before shutting off. Again subsequent presses will make the lights flash, but everything goes out again.
I am just wondering if the motherboard should stay on and give an error even though there is no cpu. Just trying to figure out if it's the cpu or the motherboard, I wish I had an extra cpu or motherboard, but that's quite a chunk of money just to troubleshoot. Any help is appreciated!
