When I turn on the computer the monitor shows "No signal" even though I turned on the CPU. I checked the cable if the monitor is plugged in the CPU correctly and still the same thing happened.

This is the sequence of what the monitor would display → AOC logo (AOC is the brand of our monitor) → blackness → "No signal" on the middle of the screen → monitor turns off → monitor button is blinking.

After several tries (powering the computer on and off again), it would sometimes work out halfway (AOC logo → blackness → Pro Series loading screen → "Your computer was turned off unexpectedly. Running automatic scan." )

From there, I could select two options; "Restart" and "Advance Options"

BUT! There's nowhere to go from there. If I chose "Restart" the screen would dim and the annoying "No signal" screen would show again and turns off the monitor.

If I chose "Advance Options", it presents me with more options. I tried selecting "Exit and continue running" because I'm fairly sure that there are no bugs in the computer for the computer to find and I just wanted it to boot up the computer properly. But still, upon selecting "Exit and continue", nothing new happens. It still shows "No signal" briefly and the monitor turns off.

First of all, you are posting in a hardware forum and no one [other than you] has any idea what hardware you are running. Post ALL of your exact system specs; ie exact motherboard, exact processor, exact pw supply, etc, etc. If this is a big box system ie dell, hp, whatever, post the exact brand model# and service tag#

From the very basic description, cold boot problems that go away after a restart are very often pw supply problems however without knowing what hardware you are running, it is impossible to help you.
