Ranom Kernel error - even after clean install can't solve

Hey guys I'm working with an issue here, I have a 2008 (early) macbook its white
randomly sometimes 20 seconds in other times after 30+ min i get the Kernel panic screen.
i reboot to a white screen, turn off and turn back on and it boots fine (until the next panic) i have tried googling the error codes but i can't find any help there
Im running Lion 10.7.5 and when i reboot and press and only 'D' it just goes to a while screen and stays there, after about 10 seconds i give up and reboot it normally. I haven't changed any hardware, and i am working on a clean Erase of the hard drive and a reinstall.

I purchased the computer a few years ago off cragslist and it has been running great, I don't use it often, but lately i have had a need for it.

Being an early 2008 and never getting disks with the machine, i can't run AHT. I have used "Techtools Pro" to test memory and hard drive and that came back ok. I don't know if thats a good scanner or not, just what i found searching google, if theres another you can suggest i will give ti a try
Any guidance will be great,
Below is the panic code:
