i'd like to know how to fix this, and is it in any way dangerous for the motherboard/pc components and the hub as well?

mb is asus k8v-mx sound and video integrated

it is very dangerous, dont plug anything into the usb port until it has been sorted, to start off with , what power supply are u using, with specs of rails aswell plz

input output
115VAC +12V 18A MAX
10A +5V 40A MAX

60Hz
230VAC +3.3V 28A MAX
5A MAX -5V 0.5A MAX

50Hz -12V 0.5A MAX

+5V/SB 1.5A MAX

whatever that means, as i said mb is asus k8v-mx sound and video integrated
and cpu is sempron 2600+

wat is the name of ur psu, i e antec, tagan, some generic one i suppose

Sparks were coming from the USB port/connector?! Thats very strange, never heard of this happening, as its quite unusual for a 5v current to do that unless there's an electrical fault.

i reckon its ur psu.
u shud get a descent one once and for all, which wil depend on ur system specs and if u want to upgrade in the future

sempron 2600+ on asus k8v-mx with 512mb DDR400
400W MAX is the psu
and 2 hdds, 80 and 120gb Maxtor
1 dvd nec
1 cdrw lg
thats about it, sound and video integrated

surely not a highend mashine, i use it mostly for emule, so
the pc is on 24/7

It could be that something isn't grounded, I know with my PSU you have to connect a grounding wire to the case but with others the SU grounds itself when it's screwed in.

I agree with Addis, it's very strange coming from a USB Connection as they do only use 5V. (And izzy there can be USB Connections on the back of the motherboard you know)

What I'd do is try a multi-meter on various parts of the case to make sure the case isn't shorting something somewhere.

I was referring to a small cable that comes form the PSU (inside the case) and screws into an mpty screw hole to ground the PSU's, most PSU's have this built in so when the PSU is screwed in it is grounded but the manufacturers of my PSU must have been smoking some strange substances the day they designed my one as that cable isn't neccessary.

Make sure that its a 3pin socket.
