My new G5 is running slowly, it hangs up frequently and things crash practically more than on my windows machine. Its not just in my head, most times when I wake the computer from its sleep the computer tries once to get back to the desktop, which it fails at, it GOES BACK TO SLEEP, and I wake it up a second time - at which point it freezes on the login window or gets me back into OS X. Apple wants me to go two or three days without peripherals attached and start limiting what third party software I am using in order to figure out what it is. So I have to go on a usage diet! I just want to bring this thing into a store and have someone confirm that this isnt up to snuff! Any ideas???
