PC First Boot - turned on, off in 2 seconds, then stayed on and worked fine

[Demuny]

I booted my PC up for the first time. Everything turned on, but then 2 seconds later everything turned off, LEDs, fans, everything. Another 2 seconds later, they all came back on, then off again, and then they stayed on. I did a reboot to see if it would happen again, and it booted normally. I haven't connected a monitor to the PC yet. Should I be worried about anything?

with a new pc if xmp profile is not on the mb and ram and cpu wont have the right speed on first boot so the mb overclock failure kicks in, it turn on/off/on till the mb/cpu and ram speed can be set. once it set the error wont show up again. make sure in the bios the mb ram speed is set right if not it may have defaulted to a slow ram speed.

I plugged in my monitor, and the PC booted fine. Installed Windows and everything seems to work good, no more boot issues.
