computer wont power up
 
it was a sign long time whenever i boot up and it will have 60% of sucessful boot and 40% wont boot and just have loud noise while the monitor is black. then i finally bought a new power supply Antec Earthwatts 380 Green thinking it is due to broken psu.

so now I got Antec Earthwatts 380 Green installed for 4,5 months and the problem was the same. when boot up 60% sucess and 40% fail. so it was not the psu. now i dont know whats causing it.

above is long long time ago. now in present time.... the system wont power up at all! i press the power button and it just make noise and the fans inside runs and video card fan runs and eveyrthing but monitor still black. shutdown and press power button again and the whole system wont run... no fan running no no lights no nothing. its like its no juice from the psu... its just press and woosh sound then empty nothing. rinse and repeat... press power button... fan runs everything runs but monitor black out...... try to power up again and it jus woosh sound then nothing no fan run no nothing. it seems like a psu problem but how? i replaced the psu and nothing solve.

now i suspect its the ram... i took all ram out and put in one by one while trying to power up the computer with each ram and still no work.

now i suspect its the video card X850 XT.... i clean the dust and everything. still no work. so i tried pulling out the VGA cable from the video card and just use default graphic hole..... still same. no work.





(the system has no beep sound when powering up)
