I recently built a system using Tech Report's guide (which is great by the way), and it happens to be the first I have ever built. I assembled everything fine and it booted up right away the first time. I installed Windows 7 with no problem and have been playing games and such.
My problem is that on the next three times I have tried to boot the system after it is shut down for around 12 hours or more, it doesn't boot on the first try. My motherboard does not beep as it does when it boots up. If I hit reset or turn the power off, it then boots up right away on the second try and everything is normal. I have left it off for around 4 hour intervals and it still boots up normally, just not after longer ones it seems.
My googling suggests this could be a power supply problem, but I wondered if anyone had any other ideas. Here is my system...should I upgrade my power supply? Could the problem be something else?
