Long time reader first time poster... So after waiting a good 20 days for my new OWC 120GB SSD to arrive I finally had the final piece to the puzzle in my upgrade plans on my early 2008 MBP (2.5Ghz, 8600M GT 512mb, etc.) First to go into the computer was a bump to 6GB of ram from 4GB. Although not officially supported I sourced out the reported compatible ram and all 6GB was working and addressable in 10.6.5. I didn't have any problems, my virtual machine ran noticeably faster and it was a great little memory boost. So continued... I trimmed my OSX and cloned it to the SSD then pulled the laptop apart. I installed the SSD in the original HD spot, removed the optical drive and installed a new WD black 500GB HD into the opti-bay. I then booted up and (quickest ever) and confirmed everything was hunky dory. Which overall it seemed to be, despite a seemingly random OS freeze requiring a reboot. Also, I now had a service battery indicator (less than one year old) and would shut down when saying it had around 1/2 hour of life. Then I noticed that my external monitor was showing artifacts and some generally fine scale gitteryness like problems (hmm... thought monitor must be on it's last legs) I had the system operational for a good 36 hours, transferring various home folders to the 2nd HD (WD Black 500GB) and creating symbolic links in terminal so that the OS would treat those folders the same for my various programs etc. (which i'll post how i did eventually as I didn't find any forum or blog posts particularity helpful...) I went to sleep last night and returned to my newly tweaked laptop with my morning americano and thats when the proverbial s%*# hit the fan. The display's didn't respond to input.... hmm thats unfortunate.... reboot. Spinning icon.... spinning indefinitely.... reboot. spinning icon.... you computer cannot boot screen. (never seen that before....) reboot. Black screen, no tones, steady light, won't post. reboot. Same thing x3. Another coffee reboot. gray screen, starts up to just about login screen then hard locks. reboot. black screen again, which leads me down the 8600M GT rabbit hole. Do I have a defective video card/logic board? Might explain the monitor artifacts....Well, luckily I have applecare, unluckily I'll have to replace my optical drive and original hard-drive because my apple tech was just in my computer replacing the ribbon cable responsible for keyboard and mouse. one last try. reboot. now i'm getting 2 beeps and 3 beeps. Memory wtf? reboot. i'm still getting the beeps but now my HD is making that sound like it's toast. I then commenced dis-assembling everything that I had done. Old HD back, optical drive back, pull the ssd and new HD. Remove the ram and replace with 4gb sticks. Put everything back together Reboot. Computer works perfect, no stability problems at all. Now of course I realize I've got way too many hardware changes to make this thing a cut and dry troubleshoot. I called MCE technologies (maker of opti-bay) and explained to them my experience. They suggested their product's board may be faulty and asked me to return it for a new one. I'm hoping that was the case, but it seems odd that it could totally corrupt me system like that. Any thoughts, suggestions, ideas. I'm thinking of taking the computer in AASP and getting them to run some diagnostics on the logic board and video card, but if I can't get it to replicate those problems it doesn't seem like they'd find anything.
