Dead mobo?

[Involution]

Hi, currently I am having a old computer which can't be turned on. The model of the mobo is p7h55-m le by Asus(http://www.asus.com/Motherboards/P7H55M_LE/).

And my cpu is i3-530

When I click on the power button,the fan of my psu spins for 1 sec and stops, without me clicking again the fan of the psu spins and stops. This process continues until I off the psu itself. For each interval to occur it take around 3-5 sec.

The troubleshoot I did include

-using another motherboard to check if the psu works. So I don't think it's the psu

- jumpstart the mobo with only cpu and cpu cooler.( check if ram or other stuff might affect)

- clearing cmos by taking the battery out and also tried replacing a new one.

- I cant take the cpu out as it is stuck due to the old cpu heatsink stand.( can't test without cpu, sorry)

I tired my best to keep components from getting static.

Before this problem, I left my comp off for 3 days straight, as I was not around. The power source was disconnected, so it's not possibility due to thunderstorm.

And yes, I know this comp is old but I would like to try my best to save it, if possible.

Is there any other way to check if the mobo really dead? Please do share thanks.

take out the RAM and install one stick into slot 1

Tried that just now, still having the same problem. I tried in both slot 1 and 2. Using 2 different sticks.

did you try the mobo onboard display output?

The mobo can't turn on for more than 1 sec , so my main concern is not on the display . As the mobo only ons for 1 sec before turning off and repeating it every 3-5 sec without me clicking on the button after once. And yes, I tried to connect my monitor to both gpu and mobo but they can't detect any input.

I tried that possibility already and it still don't work. I tried lending my friends ram (which is working) to double check if both of my ram are busted.. But it still have no change.

Go ahead and try another power supply just in case. Be sure it is the right amount of power for the system.
