Possibly due to the PSU (bad rails), bad pin contact at the ATX power connector and also possibly the motherboard. From those pictures, are those capacitors next to the ATX power connectors bulging? » Click to show Spoiler - click again to hide... « |

From those pictures, are those capacitors next to the ATX power connectors bulging? No, they are not bulging.*UPDATE (SOLVE):* Just replace it with a new 500watt PSU unit and it works perfectly now. I think i know what the problem was it seems the old PSU is a very old model where the sata connector has 5 cable and not 4, the extra 1 is the 3.3v orange cable and the PSU is only 230watt. From what i read online it said now days new HDD if they need the 3.3v it can produce it from the dc/ac change something like that so maybe the Old PSU already supplying the 3.3v and the new hdd producing 3.3v also made it short and burn that two 3.3v pins? Correct me if i'm wrong. This post has been edited by Jeremy_John: Oct 29 2013, 08:32 PM |

230W cannot power most of the modern stuff nowdays. Which requires at least 300W. Can see most branded machines go for 350W just to be safe.
