Last couple of days my MacBook (see sig) has been a bit unreliable. I can no longer play Football Manager 2007 without the system hanging and forcing me to force quit. Safari and Firefox were not working the other day, but now appear to be fine. In general the system tends to beach ball much more than normal. I fear it may be the HDD which has made some rather un healthy sounds over the last few days. I ran Disk Utility and it said my disk seems to be fine, I also ran the extended hardware test which also reported no errors. Now, my dilemma is that I go on holiday tomorrow for 2 weeks. I really need my MacBook in action so I'm going to try reinstalling the OS and hoping that helps the issues. It's worth a shot anyway. Everything is backed up via Time Machine - is it possible to reinstall Leopard (erase+install) and then copy back only certain Time Machine backed up files (music, video, apps) so as to keep my fresh install fresh at a system level? Any help would be greatly appreciated, if there's anything I haven't been clear enough on please ask me to elaborate.
