OK well its been several days since i installed the new kernel and all iss well, i havent had any lockups. system is running fine. i think this did it and it was really an easy fix . thanks everyone i appreciate the help and am now much happier .
Oh my temps range from 120's to 210 F but since ive had no lockups since the upgrade i dont think temps was the cause . i dont know what the exact cause was , but the kernel update seems to have worked
