Broken mobo, cpu and power supply.

    Hello,

    I am wondering if anyone knows any simple method to test if either of these 3 are operating as they should, although I am pretty sure the power supply is completely gone and may have taken the motherboard and cpu with it.

    I would like to recover the motherboard for future use but am unsure if it is possible.

    When I plugged in the power supply and attempted to run it, some copper completely broke open between the main power connector and a copper wound coil in a plastic casing.

    It seems to have protected the rest of the board, but I am not sure if I can solder or re-connect this broken copper (it appeared to actually burst out of the PCB board).

    I don't get your problem, where's that coper coil comes from ?
    Namely to test the validity of your PSU, the easiest way I can think of, is startjumping : connect the green wire with the black one of the PSU in order to get power on, afterwards get a multimeter and test the voltages.

    For the MOBO, it depends, some configurations will notify a missing CPU by means of beeps combinations, and some others won't.

    So in order to test wether it's the cpu or mobo's fault, you will certainly need at least one extra functional component set aside.

    Sounds like something on the motherboard burned or broke off? Please post a pic of a similar motherboard and tell us where and what.

    Ok here is a picture of the actual motherboard model (not the one that is broken, but an identical product).

    Now I understand it. Copper track on PCB which connects power plug to a copper coil on the mobo got burned?


    Yea, that can be repaired, just substitute a good thick wire for the PCB track. But, because PCB copper track burned, this is an indication there is something wrong there. Most likely other parts are burned as well. Thus, you need a professional with tools to diagnose and repair this board.

    The easiest and most effective way is to order another board like this one, and return this one. Yes, you must break a commandement doing this. But rest easy, stores get credit is merchandise is returned.


    Your CPU could be OK.
    Your PSU is probably OK as well.


    It appears to be motherboard problem. A short on the motherboard caused PCB copper track to melt along with something else as well.


    Now, your PSU should have shut down, and perhaps it did. Does your PSU still work? You could test if it works by jumping green wire with black wire on the plug. If not, it could be repaired. Inside there is a transformer, inside transformer, if you cut insulation slowly, there is a fuse. Replace that fuse with wire from inside a 1.5 WATT fuse. (you break the fuse and take the wire, and solder it in place of the fuse in PSU's transformer) Then just put electric tape over it.

    Yeah I had a feeling it might have a been a short that caused it, although the PSU is what allowed it to burn out (the generic one just refused to start, although I use it with another mobo now just fine).

    I think I may have been having issues (or at least started out with) because of trying to screw the mount the bloody board to the case.

    These new boards have bloody metal tips on all the screw holes for some reason, and no matter how I screwed any of them in, soft, hard, even if they just sat there I couldn't even get my good config to work.

    I removed them all and now it works :S.

    What's up with these new boards? If it's not allowed to touch the case then it should be built so it does not, and if metal screws are an issue, make them plastic, sheesh lol.
