Hey all, newbie here
I've got a tricky one for yall. I picked up this Mac Pro last week for $20. Pretty good deal considering the graphics card still works. But alas for that price it had to come with a catch. The previous owner already mentioned it didn't had a hard drive but other than that he was clueless. Didn't even know what model it was. And neither do I. The model # is A1186 but says it's a mac_3.0 which is apparently a built to order model? Anyways with no hd that means no OS. So after some research I decided to try and load Lion (OSX 10.x.x) system recovery software onto a CD. To boot into recovery mode via CD you are suppose to hold down the power button until the optical drive comes out and load the cd from there. But when I hold down the button it flashes rapidly (approx 2-3 times a second) then screeches one single long tone/beep. Then chimes and loads up the white/gray screen with flashing question mark folder. Now according to the service manual this means that no ram is detected. BTW this thing came loaded with ram. Every slot was filled with various types of make and size. And a red LED diagnostic light would pop up on DIMM2 of riser card B. To make things simple I took out all ram except for the Kingston FB-DIMM 4gb and placed one in each of the first slots closest to the gold plated chips on the end. Get the same error message. Now assuming the RAM slots on the logic board are dead would it be possible to desolder the dead ones and throw on new/working ones? I'm quite handy with a soldering/desoldering iron. Just wondering if anyone has done this before. Here's a youtube video of me going over the problem if it helps.
