New Computer won't detect any drives!!!!

[ProMorpher]

I just finished putting together a whole new system. I have an ASUS A7M266 Mobo, AMD T-Bird 1.4, Seagate Baracuda III 40gb HD, GeForce3 video card, sound blaster audigy platinum ex sound card, plextor cd r/rw, pioneer dvd, sony floppy drive, and a tv card. It turns on, but it won't read any of my drives, not even my hard drive. I'm new to this so please help me. I tripled check to make sure it was all hooked up right too. It doesn't sound like the hard drive is turning on so I changed the power connector that is going to it and still nothing. Any suggestions?

If you can stick the drive in another PC, you can see if the drive works. You could also try swapping IDE cables. Check the drive jumpers as well, make sure you don't have two masters or slaves on the same connection. Also make sure you don't have a "cable select" on one of those drives but not the other. Do the drives appear in the BIOS (I'm guessing not)? Maybe put a known good drive in the box and see what happens. I would pull everything and add them back in one at a time to see if they work.

hope this helps

could be a power supply issue. Only have the video card and hard drive in, then try to boot.

Check the bios as well, make sure it's set to auto detect, or manually place in the settings for the drive.

also make sure you havent inserted the data cable incorrectly.
remember, the red line is one the side nearest the power cable.

A good way to do it is to only add one drive at a time. Start with the primary master (hard drive) and work from there.
