Need to start computer twice
So, I have a weird issue. Back in 2011, I built a computer. It has an ASUS Sabertooth 990FX motherboard inside and I forget what power supply (though I replaced it last year after the original one went bad). For the last few months, the first time I start the computer, it just sits and does nothing. The fans spin, but it won't POST. If I kill the power to it and restart it again, it boots up and runs perfectly fine, like nothing ever happened. However, once I shut it down for the night and go to start it the next morning, I have to go through the same procedure again.
It never throws any errors that I can see, and it doesn't lose track of time, so I'm not sure what it could be. Anyone have any ideas?
