I travel with my computer on the weekends to an office building to use the internet because i don't have high speed connection at home.
After setting up my computer, when i switch the power supply on and and hit the reset button on my case to turn my computer on, my computer turns on for about 3-5 seconds, then turns off for 2 seconds, then turns back on and starts up normally.
this happens whenever the computer loses power.
The most recent time this happen it stay in this state for 15 seconds, no signal sent to my monitor and no post bio beep for the little speaker on my motherboard, then turned off and then on again and started up normally.

Although i haven't seen any obvious negative affects from this, but it leaves me a little concerned as to why this is happening. this didn't happen the first time few times after building my PC.

any solutions or insight on why this is happening is much appreciated.

my setup is
intel i5 4670k
Z87-PRO
samsung SSD 750gb
8GB Corsair Vengeance
GTX 770 ASUS 4GB
windows 7 SP1 64bit

Is your system OC'd? It almost sounds like your BIOS battery on your Mobo isn't working right. Do you have to correct the date and time at all after boot up?

No, I think my computer is fine i just found this on the Asus website in the FAQ probably should have look there first but it said this

"This is a power saving design which is applied to some high-end ASUS Z87 series motherboard, and this phenomenon is normal. When customer power on the PC, motherboard will automatically detect the utilization of onboard ASMedia SATA controller. If there is no device connected to ASMedia SATA controller or it is disabled, motherboard will cut off the power supply to ASMedia SATA controller and restart computer to achieve better power saving."

Interesting. You might check your SATA connections and see if you have any connected. This way you know for sure if this is a problem or not.
