Hello everyone, First of all, I've been away for a little while, distracted partly by the wonderful world of IT and Parliament and by other life issues. But onto the point - this may sounds like a daft question, but do USB 2.0 8 port external hubs use up more power than USB 2.0 4 port hubs? the reason I ask is that my old rig has started to throw up atidag error when I reboot the machine, so I was wondering if the 8 port hub could be whats tipping the power consumption over the edge so that the PC can't initialise the GPU on reboot. Of course, it could just be I need to move more devices out of the back of the main ports of my PC - or a failing power supply (although usually everything runs / initialises fine on power on). Anyway, nice to post again, there are probably more new faces than when I went into hibernate mode.
