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: Interval Since Last Panic Report: -570 sec Panics Since Last Report: 1 Anonymous UUID: 4D44E794-E199-45CB-BF24-0D58E2A038E2 Sun Dec 12 15:01:17 2010 panic(cpu 1 caller 0x9cdbfa): NVRM[1/3:0:0]: Read Error 0x00009410: CFG 0x086310de 0x00100406 0xd6000000, BAR0 0xd6000000 0x6d270000 0x0ac180b1, D0, P3/4 Backtrace (CPU 1), Frame : Return Address (4 potential args on stack) I have attached three Panic reports. Can anyone help me? What is wrong with the MacBook? Thanks Wobble.
