Greetings, I have a 2 X 2.66 Dual Core Intel Xeon with 10.4.8 and 2 gigs. It is about 6 months old and lately I constantly get the spinning rainbow ball when trying to do certain tasks. i can go stretches of time with no problems and then I have problems. half the time I have to force shut down. Relaunching the finder doesn't work. When attempting to open certain files I have problems, sometimes when browsing the internet with crap fire fox the same thing happens as well. I used disk warrior, that didn't help any. I'm not sure if there any preferences I should trash or what else I can try. knowing my experience with the hard drives apple uses it is probably the hard drive giving me an early warning sign. But I hope its not. I would appreciate any help. Thank you.
