hi all, recently bought a usb2.0 pci card (4 port) to put into my system (p3 700, 256mb, 40gb, with only 100w psu ) and it would not turn on... i removed all pci expansion cards that i had on there and tried again.. nothing.. not even a kick of the fans.. it seems like the card requires too much power that my psu cannot supply??? i run a 32mb tnt2 m64 graphix card and runs fine and also have a usb1.1 card (2 port) at the same time with no probs.. is it the particular brand having a conflict with my system ?? it is a laser usb2.0 card (cheap as they get i no) plz help and is there any other brands that could possibly work without changin my psu???
