Computer turns off 3 seconds after turning on

[kdon27]

So i just put together my very first build but i'm having a big problem.

I turn it on and it powers up alright, then turns off after 3 seconds.. on one occassion it turned on, turned off 3 seconds later and then turned up again... i turned it off and kept it disconnected just to avoid causing havoc..

please help!!

hm.. seems that it is more likely the mobo is faulty.. i might just get a new mobo tomorrow and see what happens.

any ideas why the computer stayed on longer when i had the air-conditioner cooling it down? that's the only thing that is inconsistent with a mobo fault (according to the limited reading i had managed to get done).

re-seated cpu using new thermal paste and all - didn't work..


GOT NEW MOBO! - Worked!!!!
