I'm not positive if this is an OS issue or hardware, but hopefully you guys can help me pinpoint the problem. Currently I'm waiting for Leopard (Feb. 20th... PLEASE) to do a clean install on a 74gb Raptor that will replace my 250gb Seagate as System drive. Overall, I'd say my mac pro is a pretty stable machine. I have had some burps and weird little glitches, but I'm a switcher so it's not at all out of the realm of possibility that I've borked it up somehow. I've done repairs on disk permissions and every other possible OS fix that I can find and also run the Apple hardware test, but my Mac still feels much slower/glitchier than it really should be. Hardware: 2x2.66ghz, 2gb Apple RAM, 250gb Seagate from Apple as System + 500gb Seagate OEM as Storage, 2xNvidia 7300GT Note: After I got my Mac I used it for a while, then did a fresh install of OS X after it had begun to slow down and act abnormally. This install is probably about 3months old maximum. 1. Parallels is awful to get going. Once it's running, I'm ok, but it is at least 5 mins of letting my system just sit and do nothing while it loads WinXP VM. 2. While extracting files from RAR, I can't listen to music. This was never a problem on my PC. I do realize it's disk intensive, but c'mon. Something isn't right here. 3. My GUI effects sometimes get extremely choppy and I have to reboot to fix the issue. Genie effect is most affected, but sometimes Dashboard and Expose also. 4. Sometimes app just refuse to load. They will be running fine and then next time I try to load, nothing. A bounce or two in the dock and then nothing. 5. MS Office 2004 has begun randomly crashing. Please let me know if I can provide any more info to help troubleshoot. Thanks.
