Old G4 with processor upgrade is crashing

I have a G4 running 10.4.  I upgraded the processor last year.  It’s now panicking often. Blue screens. Freezes. Fun, fun. I am sure the original processor is somewhere, nearby, packed in a moving box.
The only thing I really want to save on that tower is, predictably, my iTunes library which is on a 2nd hard drive which is mounted separately from the original disk.

I suspect a new Mac will be purchased very soon. I have an original Drobo, but have yet to purchase drives for it.

Allow the yelling about backing up to commence.

I’m a bit biased here, as I have always distrusted processor upgrades. They just seemed more trouble and expense than benefit. Now with the Intel machines, I figure they’re pretty much irrelevant.

Your G4 may be salvageable, but I really do think you need a new Mac. Bite that bullet, bubba. And to get your data off the G4, if it won’t boot to FireWire target disk mode by booting while holding down the “T” key, you can buy a Firewire enclosure or even better, a data cable such as this one, for the internal hard drives from which you need to rescue data.

Excellent work buying that Drobo. Now about those drives
