  1. hi guys,

    i had a problem as my computer was switched off suddenly.after all the checkings i found that 12v atx power connector on mother board is not functioning.

    case1: i tried connected both the 20pin and 12vatx pin and try switching on power nothing moves

    case2: i tries connecting only 20pin on motherboard the power comes and fan on the proccesor starts moving. but if i connect both the pins on motherboard nothing is happening

    so can anyone please tell me what is the problem and what i have to replace.

    you're PSU might have blown.. Replace that first.

    If its a crappy generic PSU, then it could have taken more than just itself out when your power cut.

    Does it speed up to full RPM? Or does it just flutter a bit and die, with power still being applied?

    If it just flutters thats a good indication of a blown motherboard or melted cpu, which is a whole 'nother mess of problems.
