J3355B shuts down if I connect the NIC



  • I got myself a J3355B along with a i340-T4 NIC card.

    I tested the motherboard and the RAM and had no issues/errors, but when I connect the NIC to the PCIE and restart the motherboard, all  I get is the AsRock splash screen and then the motherboard just shuts down. If I remove the card and restart, the motherboard boots up again. Does this mean I have a bad card? If so, I might have to go through the whole Ebay RMA process.

    Can someone confirm before I start that process?



  • Afraid so.

    I would… try another slot if available.  Use compressed air can on slot as well as NIC board in general in case of lose metal shavings present.

    Go another PCIe card to rest, in case is the Mobo.

    Got your 12v, Extended Power Plug hooked up (if any), lots of people miss it.

    Thanks. The J3355B is a mini-ITX board, so only 1 PCIE slot is available. It also only has a 24-pin power connector which I did connect.

    I don't have any other PCIE card available, but I can try to connect the NIC to my FreeNAS box and see if the same issue crops up. If so, then I will RMA, but if the FreeNAS board starts up without a problem, then I am not sure what to do. I will perform this test tonight hopefully.
