I have a PM G4, Dual 1Ghz w/ 2 gigs of ram. In the last 2 or 3 days a majority of my programs will shut down without warning...Word, Excel, Safari, IPhoto (had to remove a pref.folder in Library to get it working again). UT2003 quits after 2 or 3 minutes of playing. I've been with Mac for about 10 months and now the experience is reminding me of using a peecee. I'm still new to OSX but is there anything I can do to prevent all these problems or reduce them? Thanks!
