  1. I'm helping my brother put in a new mobo.
    He bought the MSI 651m-l mobo kit.

    Got everything hooked up, & there is power to the fans, but cd rom & hdd not booting up.

    He got a new 350 watt power supply.
    No luck.

    Called tech support & they weren't any help at all.

    Got a new mobo. Same problem.
    What the hell can be the problem?

    Went over all the jumper settings & connections.
    Everything looks fine.

    Please help.
    Losing my mind trying to figure this out.

    also consider the latest bios upgrade.

    I'm heading over there tomorrow.
    Haven't messed with the bios.
    Any advice would help.

    Again thanks.

    I believe that mobo has onboard sound. If you installed a separate sound card, you have a conflict. Remove the sound card and try starting the PC. If it works, you can disable the onboard sound in the BIOS later and install the sound card.

    As well as the twenty pin molex connector, have you also connected a four pin molex connector from the psu to the four pin socket on the mobo?

    I think this supplies power to the cpu, and without it, it wont work.
