Macbook Pro Late 2008 Boot Issue

Hello All!

So I have an issue i would like to throw into the ring and see if I get any responses I have not thought of yet. Let me give you a quick backstory to my recent macbook adventures.... I will start with a quick prelude story.

Chapter One:

Purchased a used Macbook Pro, Late 2008 2.53ghz, 4gb DDR3 ram with no charger off ebay. And yes, I should know better. But honestly, it only had a cracked screen but still worked perfectly connected to an external monitor and i could not pass on the price of it.

Chapter Two:

After recieving my purchase, I determined that it was just a cracked cover over the LCD screen which is easily replaced, but the backlight was out on the LCD. So i ordered a new LCD. The new LCD did not fix my issue, which then pointed me to a problem on the motherboard. I then sent it out and had it repaired.

Chapter Three:

Upon recieving my newly repaired macbook, I installed a new SSD drive, battery and replaced the screen cover for the newly installed LCD. It looks Fantastic if I do say so myself! I then proceded to install lion and I have a perfect running Macbook Pro for less than 700 bucks after all was said and done.

Chapter Four:

Now, at this point you should know why I bought it... I use it for djing. That is it. There is nothing else on this. No apps, programs, or scripts. It has an updated lion OS on it and my serato itch Djing software. There isnt even any music on it as i store that on an external 3T WD elements drive. (I only installed an 80gb SSD for the OS system). Unfortunately i have had some instances where the Mac Pro has just shut down completely while im spinning! Not good for business!

Chapter Five:

Over the course of the last year I have noticed some things happening. Longer than normal boot times (especially since it has an SSD in it this seems wierd to me) and crashing of the Itch software while trying to analyze music or just not closing itch at all when im done playing a show and having to press and hold the power button to turn off the mac. Now for the kicker... Unbeknowst to me, apparently you cant use a 65W charger on a macbook that requires an 85W charger, this i just recently learned. The charger i was using was a 65W from a white 13 inch macbook 2006. I just recently aquired the 85W charger.

This brings us to the present.....

Here is the issue. I was analyzing my music files using itch, when suddenly & randomly one of the 2 analyzing indicators would just stop analyzing the track it was on... This leaves only one analyzer bar going and the other just stuck where it is (16000 songs will take awhile with only one analyzer going). If i stop analyzing and restart it, it picks up where it left off and continues for a bit and stops again, but its never the same track or same length of time before it stops analyzing. Now I have tried this with both Lion and Snow Leopard (the white macbook 2006 has snow) and it appears to happen with either OS.

So I decided to install Snow on my Mac Pro 2008. For some reason, and I dont know why, it would not let me install snow to the partion I made on the drive. The disc would just keep rebooting the Mac pro over and over again. I know for a fact that snow works because I took the drive out of the white Macbook 2006 and put it into the Mac Pro 2008. Booted right up.

So, I have re-installed itch on lion... Still has the same problem with lion.

I have restored a copy of snow to the partioned hard drive of my Mac Pro 2008 from my white macbook 2006. This seems to be the only way to do this if i want snow on my Mac Pro 2008 since it won't boot Snow from disc or USB. Installed a new copy of itch, still the same problem.

So my question is this.... Is it hardware or software?

And to stop those from putting the obvious, I have done all the PVRAM, SMC etc resets!! I am not some 12yr old trying to make daddys computer work again because i used it like i shouldn't have. Im looking for something besides the obvious!

Sorry, but I felt the entire story needed to be told in order to get the responses I'm looking for....

And thanks for taking the time to read about my issues! Hopefully someone can point me in the direction I need to go to get this to stop doing what it's doing. I will be more than happy to answer any and all questions concerning this issue as best I can.
