Okay, I have a feeling this is probably due to insufficient RAM or overheating, but some input would be nice. My iMac has a 60GB HDD, 256MB PC133 module, 700MHz G3 CPU. It is currently running MacOS X 10.3.9. When I am in Safari, it seems that if I visit some sites (heavy data ones), Safari seems to "unexpectedly quit." 😡 When running SNES9X emulator, I can play for a while, then the iMac freezes or tells me to restart it😡... Any suggestions? 😕
