    these kernel panics are driving me nuts, i cannot understand why someone cant read a kernel panic

        and know what the problem is, all this stuff safe mode, hold this key hold that key and you still have the problem if at apple they know the problem so should the novice a code is a code its meant to be broken

            one of those codes says exactly what the problem is. why such a secret???????

    Kernel panics are often caused by hardware issues.  Diagnosing a hardware issue is best done by someone with expertise who can look at the actual hardware.  No one is trying to keep any "secrets."

           going to take out logic board again read alot about thermal paste, however last time it was out

                i did not notice where the paste went, saw no gunk as such is there a diagram that shows where it goes

                  i get the gray screen, apple logo, spinning gear, all fans race, then the restart computer logo

                      once or twice i managed to get to safe boot, but it shut down with the hardware chec disk

                         running, can i narrow this down to heat related, power supply getting too hot???

                           what would be the first component to heat up. spoke to a guy on the phone

                             where i live had same problem, said its not power supply, it was a heat sink

                                 problem, again with that thermal paste, he fixed his???????
