Hi everyone. Hope you could help me diagnose my MacBook's problem. My MacBook is about 3 years old now. Its processor speed is 2GHz and originally had 1Gb of RAM. It runs on OS X 10.4.11. I don't install any junk and keep the desktop clean. I mostly stream video, and edit photos. I guess the probs originally started with my my Safari randomly closing on me. Eventually, the MacBook would freeze when I opened iPhoto. I figured it's about time I get some more RAM. So I upgraded from 1Gb to 2Gb. I also formatted the machine and did a clean install (I think that's what it's called). So I don't have any of the above problems much or at all anymore. What I do have is an extremely slow start up. I'll see the apple screen for a while. Then, the Mac OS X loading screen for short while relative to the other waiting periods. Before I could use the Mac, I'll have to wait on a blue screen for maybe 5 mins before everything else including the mouse arrow appears. Aside from the slow start up, the Mac freezes if I close it and then open it up. The beach ball also regularly appears when downloading updates. A recent finding that I noticed is that the MagSafe wiring is partially melted. I read somewhere on here that not using a battery with a MacBook or having a bad battery could slow down the start up process. Could a damaged battery as the result of the MagSafe adaptor be the root cause of my problems or is it one of many root causes? Update (1/11/10): Last night my MacBook didn't boot up. It would show the loading screen with the apple and then switch over to a black screen that looks similar to DOS. It apparently continued to try to restart but failed and ended with a message, something like "I have no name!". I appreciate any help. Going to get a new MagSafe adaptor today.
