Alrighty, so I have a 15" PowerBook. 1.5 GHz PowerPC G4, 512 MB. I know little about computers. Safari, iTunes and MSN Messenger will not open on my computer. Safari has been doing this for a while, iTunes and MSN just since yesterday. When I click on the logos, they will bounce in the toolbar and then just stop. The log that I somehow found earlier reports them as crashing. Any tips? I can live without Safari, but no music is killing me... Any suggestions would be greatly appreciated and if you need any info on the system I will do my best with that. Thank you so much. And if it helps you want to help me... today's my birthday. AND my car broke down earlier. So awesome day.
