So here is my current issue. Everytime I boot my pc up in the morning after sitting all night it will not post correctly. I start it up everything turns on the fans spin properly all the lights in the case are on and functioning except the monitor does not power on right away then the pc reboots atleast once sometimes twice and boots perfectly my monitor turns on and everything is fine. Like i said this only happens on a cold boot. All my bios and drivers are up to date. I have tried a different psu i have tried removing memory to see if it was a bad stick no matter what it still happens on a cold boot. If i shutdown my pc let it sit for 5-10 minutes and start it back up everything is fine no issues at all. It's a very odd problem which I have never experienced. Below are the full specs of my system. Any ideas would be greatly appreciated.

Make sure nothing is overclocked and see if the problem still happens. You can also uninstall all the hardware and reinstall it to see if that helps. Past there you could be getting into a cold solder joint.
It's probably a motherboard problem. Sometimes motherboards come faulty and when turned on they'll go into a boot loop. How old is the motherboard? If it's still under warranty you can try to get an RMA from ASUS.
