Power-up - down - then up.

[adrianxw]

I have recently put together a new machine, MSI P35-Neo2 MoBo, Q6600 CPU and an 450W Enermax PSU. When I press the power button, the system immeadiately springs to life, lights on, fans running, but after about 1 second, it powers down to an apparent lifeless state. After about another second, it powers back up and then boots up and runs normally.

Why is it doing that?

A power cycle is normal behavior for many chipsets from a cold boot. Was this the first boot since AC power was applied to the system? If you shut down through the start menu and them turn power on with the front panel switch it should start without the power cycle.

Are other parts hooked up? Like ram?

I know Asus motherboards do this. Though they only do it under two circumstances:
#1 Power has been removed (unplugged from outlet), then restored
#2 A critical BIOS setting has changed such as memory or CPU parameters

It should only do it on the first boot however. After that it should boot up on first power up.

Yup, if I shut it down from the OS, then power up again, it does not cycle. Reading the MSI link, it would seem that this is normal - cheers folks.
