Yesterday my computer froze solid. This is actually an odd thing even for my computer (usually it just breaks without warning). I restarted the computer and continued reading email/surfing/whatever I was doing and then went to bed.
Today when I got home, the computer was frozen solid again (with the screen saver on). Fearful, though very unsurprised mind you, I restarted the computer and it froze when it hit the gray Apple logo but before the circling arrows appear. Hard restart and it freezes again. Disconnect everything except the monitor and keyboard/mouse and it still freezes. Zap the PRAM and when it starts up, I now drop to the lovely Open Firmware with:
DEFAULT CATCH!, code=300 at %SRR0: ff84755c %SRR1: 0000b030
I really wish I could link it somehow with something I did (things that make no sense irritate me), but I'm pretty sure there are other Mac users who check their email (and listen to music with iTunes _at_the_same_time_ *gasp*) and don't have such problems...
More detailed computer specs:
Power Mac G4 2x800Mhz
Mac OS X 10.2.4 (one partition; no Classic support)
512MB RAM (stock)
Geforce 2 MX Twinview
a low-end ATI card (for second monitor)
LiteOn 52x24x52 (replaced CDRW/DVD combo)
2x80G Western Digital hard drives (RAID1)
stock Zip drive
stock SCSI card
Thanks and I look forward to any help anyone can provide.
