continuos Kernel panics. I DID EVERYTHING. HELP

I have a late 2010 Macbook pro. one year ago it began to restart suddenly without evident cause while doing different duties. I erased and reinstall everything and it didn't work. So I thought it could be the RAM so I downgrade to the original (4gb) but it doesnt work neither. recently I've bought mountain lion and I did a clean install, hoping it solves the problem, but no. 😟 I also did a ram test but it appears to be OK.

so here is the kernel panic report.

any ideas? does anyone know how to read this?

PLEASE HELP

thanks
