Macbook is freezing.

Hello.
I have a 2.4 ghz intel core duo macabook (silver casing) that i purchased this fall. Im running os x version 10.5.6. I had 2 gigs of ram that came with the computer and recently upgraded to 4 gigs.

I recently (after i upgraded my ram) starting having issues where my computer will freeze. If itunes is playing it gets stuck on 1 second of a song that repeats over and over. I can't turn anything off and the only way to fix this is to remove the battery.
I downloaded member which made the computer freeze again when i tried to run it, after restarting, the computer no longer detected my airport card. it didnt appear in my top bar and when i ran the system profiler it didnt show up as well.

This was last night, this morning after leaving the computer to sleep all night, it all seems ok. Id obviously like to resolve this as it can be quite frustrating to be working on something just to have you computer freeze for no reason all of a sudden.

I briefly spoke to an IT guy at work who seems to think it might be more of an overheating problem rather than an issue with the new ram but i figured i would get the opinion of the people on here.

any help would be greatly appreciated.

Thank you

So in other words:

"My MacBook was working fine before I upgraded the RAM. Now I'm having weird problems. What could be the cause?"

Sure sounds like bad RAM to me. Why don't you try removing the upgraded RAM and see if the problems go away? If they do, then I think you have your answer.

I love how every problem in the computer world can be blamed on "overheating." iTunes freezing and your AirPort card not showing up is unlikely to be heat related. It sounds hardware related, but not heat related (possible RAM/logic board issue, speculation at this point). If you work in another user account, does the same problem occur? (Likely.) If you swap the RAM for the original, does the same problem occur?

ram should be life time warranty from most manufacturers. just give a quick phone call and ask.

also check about return policy of where you bought the ram.. if it hasn't been too long ago..

If you have AppleCare, then you have TechTool Deluxe on the DVD that came with the AppleCare box. You can Test the RAM with TechTool Deluxe. I believe there are online tests for RAM too, but I've never used them.

You don't generally have to "prove" anything to reputable RAM merchants. A quick call to inform them that when their RAM is installed, things go funky but don't when it's not installed is more than sufficient. Take note of what MacDoc told you about the speed of the RAM (this could be the issue instead of just "being bad") and proceed accordingly.

As previously stated remove the new RAM, replace it with the old. If the problem goes away it is RAM related.

RAM may not be defective it may just not be perfect for your Mac. There have been numerous threads on this topic and Canada RAM is The Authority on what is right for your Mac.

Here is one current thread that should illustrate how important buying the correct RAM can be.
Help, after upgrading to 4GB RAM, iMac won't start
