hi, i have this situation wherein my macbook, after a kernel panic and reinstallation of the software won't accept the previous strontium RAM (2x 1g 667htz PC2 5300)that i installed. before that kernel panic it worked perfectly fine but now the sleep indicator just keeps on pulsating but it doesn't boot up. when i install the original RAM provided by Apple it worked fine. i tried mixing different rams but only the Apple provided RAM works. the other Slots says its empty. can anyone help me please..
