mac wont boot

Hi , I bought a 2nd hand G4 which was fine for a couple of months but after a couple of problems ( system preferences disappeared , safari wouldnt launch ) , which occurred shortly after the last apple update I foolishly decided to reinstall osx tiger .
The reinstall looked to be going ok until I got ot the bit that says ' restart computer to finish installation ' , on restarting there was the normal start up chime , then a grey / off white screen with the apple logo , then nothing ..it just stays at this screen
the start up disk In using is a copy which was supplied on 1 dvd so I dont know if this is the problem , but I do have the apple original system restore & software restore disks and get the same result with them
also I am using a lacie firewire dvd drive as the internal superdrive broke , so Im wondering if pressing C at start up still works ..
tried booting in single user mode and attempted to type in 'mount.. 'etc but it doesnt register - I get a couple of pages of text inc. stuff like ' failed to load extension ' 'couldnt alloc. class ' 'cannot provide time of day ' ' RTC did not show up ' & ' com.apple.driver.AppleMacRucPCI ' , (the last one in yellow )
then ' still waiting for root device ' repeated ad infinitum...
have tried waiting but after an hour its still the same
Is this salvageable ? any advice greatly appreciated
 
01. Relax and take a breath.
02. Consider pressing the CUDA button.
03. Verify that the clock (backup) battery (1) is also of proper voltage.

(1) Types of clock batteries used in PowerMac G4 models.
922-1262 (3.6 Vdc Lithium), if PowerMac G4 - PCI model
922-4028 (3.6 Vdc 850 mAh Lithium), if PowerMac G4 - AGP through Mirrored Drive Door 2003 models.
 
thanks ,
pressing the cuda button didnt seem to make any difference ...

its a PowerMac G4 ,AGP , 400mhz. ,dual boot ,
the previous owner upgraded to 1 gb memory and added a second hard drive , the only thing I have added is a PCI card with usb ports - I have seen suggestions that when theres a problem you should remove anything thats not apple / part of the original setup , am not too keen to do this as I'm not very technically proficient but if theres a good chance of it making a difference I'll attempt it . Any thoughts on this ?
 
yank the usb card. i had one that kept my g4 from even booting. pulled it out, and my mac worked again. what got me was that the card had worked in my older pci macs.
