Macbook crashes with 4 Gig and not with 2 Gig

[Wobble]

Hi,

After a static electric shock, my ethernet port is dead and the Macbook Pro crashes; freezes and only a hard reboot helps. But it only crashes with 4 Gig installed and memory use over 2 Gig. Installed just 2 Gig it keeps running, even with all the memory in use. It run's with either of the 2 Gig DIMMS installed, so the DIMMs are fine.

The Panic report says:

I have attached three Panic reports.

Can anyone help me? What is wrong with the MacBook?

Thanks Wobble.

Does it work with either stick of ram in EITHER slot as well?

yes, 2 gig works in either of the two banks

the panic occurs in your graphics card.
but as you have the 9400m and it uses the main memory as its own i would still say its your memory.
also using the other graphics card, 9600gt or whatever might narrow it down as it has its own memory.
