[QUOTE="Flenix, post: 1404715, member: 252376"] Whilst waiting for your reply, I did some more ram tests. I looked at the original configuration (I always revert back to how it was when I got it after any tests) and if the computer was up it was like this: Empty Empty 256 512 GAP 512 256 Empty Empty So, I pulled everything out, and looked at the RAM. All are Samsung, matched except the amounts so no mixed brands or anything, so I tried this: Empty for all top 4, 256 256 Empty Empty Power, flashing as usual, nothing special. THEN, I tried this: Empty Empty Empty 256 GAP 256 Empty Empty Empty Pressed power, didn't expect anything and CHIME, it did the startup noise, I got my ? on the screen back! Now, the HDD from my old macbook was the next step - made no difference. Next I'm going to try a blank HDD, and install a fresh Leopard on it if it'll let me. Anything I should know before I do this step? [/QUOTE]
