Blue screen on start up

[sabusforms]

Hi everyone,
Wheneveri start up my Imac G4 Superdrive 800MHZ 512 MB (desktop ) , I get a blank blue screen. But if i "safe boot" it starts up fine. Can't determine what the problem is. Bought the iMac from new about 8 years ago & have the original instal disks. Can anyone tell me what maybe causing the problem & how to fix it . Would greatly appreciate any help, thanks:

What version of Mac OS is on the machine? Old Mac OS? OSX and if so which version?

Still hoping someone can assist with my problem above. Have not heard from dtravis7 since last contact.

If I were you, I would back up all the data and do a clean reinstall of Tiger. If it's any kind of software problem, that'll fix it. If you do that and it still won't boot properly, then you're looking at a hardware failure (logic board?)
