i just got an imac g5 off craigslist the guy said it worked but of course it dosent. when i push the power button the white light on the front flashes once and it makes a noise like its about to start for like a split second but nothing.
Some hardware fault. You're going to have to find someone who knows how to repair Macs (but it's probably going to cost more than it's worth). Either that or ask for your money back (was it sold as "in working order"?). Edit: You should try Apple's troubleshooting procedure first: http://support.apple.com/kb/HT2173
Ya it was.
