It sounds like a power supply failure.

hi all,
newbie to this group. have a 2004 G5/1.8 DP all stock except 4 x 1GB
RAM and second HD. isolated stand-alone machine not connected to LAN
or internet. has run in this configuration flawlessly since i bought
it in 2004. today while executing a command on video file, something
i've done hundreds of times before, the processor fans began spinning
up to levels that had never been reached before, and when i tried to
move the mouse, the cursor was frozen in place. as the fans continued
to accelerate, i yanked the power plug.
i left it unplugged for 20 min to cool down. when i plugged the power
cord back in and tried to start up, no chime, the power LED indicator
on the front panel lit dimly for a few seconds, then flickered rapidly
between normal brightness and dim, then came on full brightness, and
after a few more seconds, a screen i have never seen on a mac
appeared. it looked similar to an old DOS boot screen. it had some
info about the machine, and a blinking cursor on a command line with a
simple carat (>), and instructions to type either "mac-boot" or "shut-
down" and hit return. i typed mac-boot and hit return, and got a
white screen that lasted 10 minutes before i manually shut it down
again by hitting the front power button. i went thru this over and
over, 6-7 times. twice the chime sounded, but cut off abruptly and
uncharacteristically in mid-chime. same end result. the most recent
time, it sat with the white screen for several minutes, then i got the
blinking system folder/question mark icon on the screen and it won't
go further. i've put the original system disc in the DVD drive, and
it spins up for a few minutes, then ultimately spins down and self-
ejects the disc. it's done this three times now.
WTF happened? what do i do now?
TIA to all who reply.
john
