Well I have picked up a powermac g3 from the local computer recyclers for free and the case isn't in perfect condition but does turn on the only problem is no video I've tested the hard drive in an imac and it has os 9 for some reason I cant get it to reset the vram and the speaker makes a wired fuzzing noise.
Can some one help :confused:

Could well be a bad video card. Take it out and re-seat it just in case the connection is poor. Replacement cards can be picked up very cheaply via eBay on occasion - I bought one a while back for around 5.

There's a possibility that there may be other problems, but the video card is the most likely.

Could also be faulty ram sticks. How much ram do you have? This happened to me one time. I had 4 X 256. Took them out one by one and rebooted. The second one I pulled was the wrong type of ram. After that it was fine.

Have you tried resetting the pmu? Small black button on the logic board?
