Ok Im not sure the "Exact" kext that was causing the problem because i went in and took out all the NV navida ones and all the ati ones that had nothing to do with my 4850 and the geforce drivers and OMG it booted. Im going to redo my install i think i messed something up in the install but to load and not be in safeboot was a godsend. I now see hope. hay BTW what sound kext did you use. becuase i had no sound. Thanks for your help.
