Hi, so,recently my motherboard Asus P5KC decided not to post,tried everything,different psu,no ram,just cpu and board and same thing always, cpu fan & psu start spining,then after about 3 seconds they stop,then they start again etc..
Then,after some time i decided to try again,while i was shorting power switch to turn on,i touched speaker pin, it sparked,and after that it posted few times,so i put everything else in,gpu,ram,etc and it boots into windows,after few hours i decided to switch te cpu fan for one more silent,and switched,and now it wont post again,same reboot thing happens. tried again with first fan,same thing,sparked mobo again,same thing.
Ram,psu,gpu,cpu..everything works,tried it on different system.
Any ides,help?
I tried reseting bios,taking out a battery,tried all combinations outside of a case,etc..

Noup,everything is fine as i can see..
basically mobo sometimes post,sometimes not,and when it does,everything works fine except pci cards.
