Try to turn the power button as fast as possible don't make it to long

Here is a good step-by-step process to narrow down the problem to a specific component.

when i press the power the cpu fans starts nad then stops and then starts again and then stops and never starts again.. I have to remove the ac power and start again to start the cpu

You don't have a different power supply that you can try?

ya i also checked it with another psu but still same result.. Can it be a fault of the cpu???

mmaatt747 · Apr 30, 2014

Could be but motherboards fail much more often than CPU's.

Do you get a series of beeps or any LED's lighting on the motherboard at all. Sometime these are error codes telling you what is wrong.

i bought the board yesterday and a new hdd.. My processor and ram are old.. My ram and cpu came from my previous mobo, which was faulty.. Testing the cpu on a friends mobo is not an option for me. I tried running the mobo outside the case with cpu and hsf only, but still the same result. There is no led or speakers in my mobo. Can i start the mobo without the cpu and hsf???

mmaatt747 · May 1, 2014

Yes you can it wont' hurt it. But it wont' accomplish anything either as it won't do anything without the CPU. My motherboard did not have a built in speaker and I had to buy a little speaker that plugs into a speaker header on my motherboard to troubleshoot a problem I had. Something like this: http://www.frys.com/product/6488702?

Have you tried booting it with just 1 stick of ram to see if one of the sticks is now faulty?

i tried my frnds ram but still same.. I forgot to told u that both my cpu and psu stops after 5 secs and not only the cpu fan.. If i start the mobo without cpu and hsf, will the psu fan still run?

mmaatt747 · May 1, 2014

I don't think it will. Motherboard will detect no CPU and power itself down (along with the PSU). I believe you have received a bad motherboard.

how can i check that my mobo is not shutting down my psu?

souvikdas7 · May 2, 2014

i new thing i noticed that if i try to start without cpu and hsf then after 5 secs it doesnt stop, it runs normally. But as i dont have a cpu so the is no display. So could this mean that my cpu is dead?

mmaatt747 · May 2, 2014

It's hard to say. A motherboard won't do much without a CPU, so even a bad motherboard may not make you aware of a problem if there is no CPU installed.

If you have handled the CPU with care and haven't bent any of the pins since it was installed in your last motherbaord, my bet is still on the motherboard being the issue because they are so much more likely to be bad than a CPU.
