I'm betting you're getting what is known as "kernel panics". You are probably getting the "restart" message written in about 4-6 different languages after a short time after starting up your computer.

The #1 cause of kernel panics (like you mentioned)...is trouble with the ram. I would bet that if you removed the new ram, and installed the old ram (which you had no problems with I'm assuming)...that your computer would be stable.

The new ram you installed is either:

- the wrong ram type
- incompatible ram
- you have the correct ram...but it's defective in some way.

Macintosh's can be sensitive to the ram used. If this ram was purchased on e-Bay or from a local electronics store...it may work fine in a Windows computer...but not in a Macintosh. You need to get ram that is certified to be compatible with the Macintosh model you have...or if you do have Macintosh compatible ram...it could be defective.

Hope this helps,

- Nick

Techtool and Apple Hardware Test doesn't always find a fault, unless something is totally dead.
So, even though it says that everything passed, it doesn't really mean that there are no problems.
Frustrating, I know, but just the way it is.

Thanks for the help, I bought this RAM:

OCZ 4GB (2x2GB) DDR3 1066MHz Laptop Memory Kit CL8 1.5V | Ebuyer.com

Guess i'll have to sell it and get crucial RAM or something, I wasnt aware Mac can be picky with RAM, lesson learnt.

That may have been true at one time, but since the Mac moved over to x86, I haven't found that to be the case. I'd be willing to bet you've just got some bad memory modules. Have you tried contacting OCZ? They're a pretty big player, I'd be surprised if they didn't have a lifetime warranty.

That's because OWC is not located in the UK...it's located in the United States. But folks all over the world have used OWC...with lots of positive feedback.

And you will find just as we do in Australia, OWC, even with first class USPS mail, to be much, much cheaper than local suppliers with delivery in seven days. They are Mac specialist with lifetime warranty on their memory.

Took out 1 of the modules, laptop runs fine, swapped in the other one, laptop works fine. Gonna put both back in, maybe it just wasnt happy on first install.

When you live here, waiting a few days for quality RAM to arrive isn't really an issue :)

Glad you're up and running again!

put the 2 modules in, Firefox randomly crashing again.

Maybe some dust in the contacts on the 2nd slot?
