I have an IMAC G5, with OS X 10.3.9 , and a couple of weeks ago all the icons disappeared off my desktop and I am now not able to open any applications such as itunes, iphoto, any files, etc. I can open Safari, however, when most pages load I get a pop up window saying my shockwave flash plug-in failed and it usually will not recgonize some image on that screen. I can click on the apple and get into preferences and what not but everything is greyed out for the most part and not able to access. I cannot play any video as that locks up the cpu and eventually it just shuts off. This happend about 2 years ago, and I think within a month it came back. Can anyone shed some light on this situation?
