Imac G3 upgrade problems

I have an older imac g3 I am putting in a bigger hard drive and some new ram and im having several problems. first off I got pc 133 ram, which I thought was the right stuff but it didnt work (i.e. wouldnt boot) so I put in old ram and it booted up the the install disk like it should, but now it will not recognize the drive when it says select a place to install
i've tried the disk utility repair verify and every thing else I can think of

Any ideas are welcome

I am in need of some help asap
Thanks

i can sell the ram i guess I really like to use it but im more worried about getting the hard drive deal figurered out
thanks again

any ideas anybody

How big is the drive? The older G3s don't know what to do with drives bigger than 128 gigs (formatted).
