Re: Boston Acpustics BA745

You cannot plug the phono jack directly into the motherboard, there needs to be another piece that you can add, it has a yellow speaker sticker that you install into the computer, onto the motherboard. it is not an add-on card, but an accessory you can buy. this is because the speakers are self-powered, meaning that they need power from the motherboard instead of an AC adapter

How do i connect the boston BA745 comp. speakers to my gateway desktop?

Assuming you have the BA745 2.1 speaker set up, all of the cables connect to the subwoofer and then to the computer or the satellite speakers (these are built into the speakers IIRC). Take the cable with the black box (2 pins) to red and green. The red and green plugs go into the matching color ports on the computer and the pins on the black end fit into the jacks between the those for the two satellites. Plug the single end speaker cable into the subwoofer port all the way to the right on the back of the subwoofer. Plug the wire with the two plugs into the matching color jacks (blue to the left, red to the right). Then plug in the power adapter cable in the farthest left jack and plug in the other end to a surge protected power strip (that is plugged in and turned on).

If you live within the United States, you may be able to go to BestBuy or Radio Shack to get a similar power cord that will power your speaker system. Just try to get an idea of the shape of the connector.

U may have un installed your sound card. find your product driver disc that came with your computer and install the sound card drivers. if you do not have the CD, go to the product website that made your sound card and get the relivent drivers.
Hope this helps :)

I have no sound

Yes you must have the correct drivers installed. If you formatted your drive, you will most probably have to download all motherboard drivers also
