When I first push the power button on my system, I see the fan starting to rotate for a couple of seconds as though it is booting up, although nothing is shown on the screen. The fan then stops spinning and nothing happens for a further few seconds before the system appears to come to life. The system then boots up without a problem and you hear the hard drive reading etc. Once booted the system is really stable and there are no problems.
In light of this I ask if this is normal for my system to boot like this (it has always done it). Is it anything I should be concerned about? Why is it doing it?
The specs of my system are as follows:
600watt Silverpower PSU
Antec 300 Black Gamers case
Asus P5Q SE motherboard
Intel Core 2 Duo E8600
2 Gb (2 x1) Corsair XMS DDr2 800 ram
Asus EN8800 GS HTDP 384mb Video card
