uh, not necessecairly...i had teh same prob, before a fan broke and a wire hit my vid card...well sounds like ur ps is dying/dead, and its not sending out the right voltages....and hey welcome to the club, i got the same vid card u do, 3dfx voodoo3 16mb...k now about the voltages. a computer is a very precize peice of electonices and needs exact voltages inorder to function correctly. your harddrives and fans will spin when given power, but the motherboard needs the correct power in order to function correctly. to me it sounds like your 5v rail is fried...get a multimeter and check the 12v(red/black next to it) and the 5v(yellow and black next to it) and they should be exactly 12v or 5v give or take about .2 volts, if there is anymore fluctuation of either the 12v or 5v rails more than .4 volts, then the ps is shot. also the ps could be underpowered, as in there are too many devices in the system, the cd, hd, and floppy drives all draw power. try dissconnecting the hdd, cd, and floppy drives from the power supply and see if it will turn on, with the 12v atx connector connected on the motherboard. if still nothing, see if it is still under warranty and rma it, and get a new one, but if not, upgrade the ps, mobo, and cpu...
