Q:my portable HD has 2 USB cables, one for the computer and one for power... why?

many devices get power from usb. however the new hard disks, required higher current/power to run and it cannot be provided through single usb cable. hence you have to use two cables.

Q:My power supply cable to the motherboard is only 20 pin and the motherboard has a slot to take a 24 pin power cord. The 20 pin will fit but 4 slots are just left empty. The motherboard LED light comes on showing it has power. When I try to boot up the motherboard runs but the hard drive doesn't boot or the screen isn't working. Could this be b/c of not having a 24 pin power cable?I know the video card and HD work b/c I just transfered them from another motherboard that was a 20 pin. Any ideas?

Yes it will work, but it may affect your system's performance.

Q:I bought a 1999 Volkswagon jetta and there is no sound coming from the speakers. There are speaker cables, power cables, and input cables in the trunk. The powers cables ( there is 2 of them) are both connected to the negative terminal of the battery. There is also 2 input cables. Do I need an amp in order for my speakers to work? If I do how do I connect it? I connected my ipod to each speaker individually and they all work.

what your probably missing is actual RCA cables from the head unit or you speakers were supposed to be connected to a amp and when the original owner took the amps he didn't connect the amp back to the stereo. so if you want theres more than one thing you can do. have a shop connect the speakers back to the head unit. get an 4! channel amp and have it hooked up also by a shop or you can try your self but i recommend a shop doing it if your not confident. but theres really no mechanical problem so you don't have to drop any money on replacing any speakers certainly if they sound good up to your quality when you heard them.

Q:So I finally bought a quot;boss blues driverand when I got it, I assumed it didn't work, because it didn't turn on, I tried it with an adapter and still nothing. So I decided to take back to the store, the guy who helped me plugged in with a power cable and used a battery, and it worked. MY QUESTION IS; do you need both for it to work? Or is there another option, for just the power cable?

I have the blues driver and it is my favorite pedal you need one or the other you have too make sure its hooked up right the out put goes in the amp and the input goes in the guitar

Q:so I bought a new power supply to go with my new case and motherboard, and when I recived the new power supply it didn't have a power cable That Plugs into the wall, can I use the one from my old power supply or will I have to get a new one? Cause I tried using it and my pc didn't turn on, or is my power supply that I got possibly dead?

every power supply I've gotten for years uses completely standard, detachable power cords. I've never yet seen one that will not use the same cords as all the others. Use the one from the old supply
