    Dead MoBo after Recapping

    I am a newbie here and have enjoyed reading many of the posts in search of a resolution to my problem. I have yet to find one. I have recapped several boards in the past and brought all but one back to a productive life. The one that is giving me a problem is an Asrock P4V88. I was getting BSODs like crazy. I had tested everything on the board that I could and decided to replace the bulging caps on the board and all others that even appeared to be OK. Now as I try to test the board, it won't power up. I have confirmed that the PSU is in good shape. It is supplying the +5 volt stand by voltage. Nothing happens. The PSU does not turn on. There are no voltages at the PSU. I am able to test the PSU and it tests good. I can't seem to find the problem. I had recapped 2 other boards at the same time that are working well. Does anybody have any ideas? I would appreciate any suggestions or help.

    Thanks from a gratefull newbie,
    Paul

    post a pic of the recapped board.
    asrock=cheap asus.
    asus marks their caps backwards.
    common newbie mistake to asume the mark=neg.

        One other note... I went by the markings on the old caps..not the board marking.

          then its likely a bad solder job or a trace/thruhole damage issue.

            The attachments are the pictures of the mobo. I had considered a possibility of thru hole damage, but did not notice any problems when I removed the old caps. Would removing and replacing the existing caps be worthwhile? The only nones that gave me any problems in the removal were the ones arround the CPU socket

              Since I haven't seen this posted as a possibility yet, I think at this point it might be a good idea to check also and see if maybe you might have a solder bridge somewhere. I tried to inspect your photos closely but wasn't able to tell.

              Good Luck!

                Suggest putting another mobo into the case with same setup if you can , confirm that it is the mobo (recapped) that isn't working before doing anything. A jolt may have messed up your PSU to CPU power supply. Or change the PSU to new or known good one.
