i Have aDimension 3000 and have an error code 0F00:136C...

That probably means that you didn't have a CD in your drive when you ran the test. Did it tell you it needed media like the resource cd in the error message? Try running it with any software disc in it (not a movie or music cd) and try it again and see if the error still comes up.

thanks I tried that but am still getting same error code.
