experienced mac users I need help

[bignose]

I bought a imac 6,1 on kijiji that I was going to use for internet and movies for the kids. But I'm having troubles with graphic glitching and locking. The last owner upgraded to snow leopard osx and left discs from his 15" laptop (osx 10.5.5) in the box. Soooo I didn't get the original os and from what I've researched so far snow leopard is not compatible with my iMac. I think it's a software problems but I'm new to Apple.
I've owned a iMac 9,1 for a couple of years and have never had a problem but I'm stumped with this computer. I feel ripped off at the moment so if you can help I will give you a frag from my tank.

the laptop disk isnt going to work on the imac.

you'll need to find an OSX disk thats for imac. probably before snow leopard

its probably because imac 6,1 isnt intel so the drivers are all messed up

This iMac has a 2.16GHz Intel Core Duo processor. Here is a link to the specs 24" iMac 6,1

iMac 6.1 is a Core2Duo INTEL chip, the problem could be incorrectly seated ram module, after checking I think preforming a clean install of current OS would be best.

Here is the specs for 6.1 model.

I think you should remove the ram from the computer, make sure both chips are from the same manufacturer, the computer will handle OS X 10.7x so this means you can install Lion, right down to Tiger 10.4.

If you have a current mac with Lion installed, you can download this tool from Apple

Use it on your iMac 9.1, the tool will read the recovery partition, and then create a recovery on a USB drive; you can then use this USB drive to install Lion on the 6.1 iMac, do a completely fresh install, not an upgrade.

If you need help learning how to do a fresh install send me a PM I will help you with detailed instructions mate

edit--

Here is a link that will guide you though a clean install

If you do require a Snow Leopard disc I have a retail copy I can drop in the mail for you if you like.

My 9,1 came with snow leopard installed, the 6,1 also came with a copy of snow leopard.

It's a retail copy of Snow Leopard, or laptop recovery discs ?

If you are trying to use model specific recovery DVD's it will not work out properly mate, you will need to use a retail DVD that looks like this


The grey topped discs are no good for different models mate.
