Its important the replacement PSU is as capable as old one was or even better, wattage wise. Of course all connections MUST be done and in proper place. If this has been done and it still refuses to work, you have a secondary problem. When the PSU failed it *may have* taken down another device/component and refuses to boot or power-ON. If HD or CD dreive, etc., replace and hope it continues to work. However, if the mtrbd. is zapped, then consider another to replace it. In most cases, fixing the mtrbd. won't be practical or becomes troublesome as time goes on, of course this depends on your repair abilities. If so, eliminate any device/compotent before installing on new mtrbd..
Hi all after a little help here,
i Have a MSI K9N2GM MOTHERBOARD
ONE DAY WHILE TURNING THE SYSTEM ON VIA THE POWER UNIT POWER SWITCH AT REAR IT CRACKLED AND THEN THE SYSTEM WOULDN'T TURN ON. THE LIGHT ON THE POWER UNIT WOULDN'T ILLUMINATE AND THE FANS FAILED TO START.
AS SUCH I WAS UNABLE TO TEST ANY OF THE SYSTEMS. NOTE THAT THE POWER UNIT WAS CHECKED AND CONFIRMED FAULTY HOWEVER WHEN I CONNECTED THE NEW ONE UP THERE WAS NO POWER LIGHT ON THE BOARD. POWER UNIT WAS GOOD QUALITY 'OZ' ONE WITH SEVERAL SAFEGUARDS SO IM UNSURE WHERE TO GO FROM HERE
ANY IDEAS WHAT TO TRY NEXT ? IM HOPING THE 9850 PHENOM QUADCORE BLACK EDITION & 2 x 2gb 800mhz ddr2 ram ARE STILL ALIVE !!
