Hello there,
I have an iBook 14", 1.33 Ghz which has outrunned it's warranty.
Well after using screen spanning doctor (maybe too abusively), my computer ended up with the
blue screen startup... I didn't have much important documents on the so I tried cleaning the harddrive and reinstalling Tiger. However, the machine freezes sometimes before the CD loads, sometimes after I chose the language, somtimes in the middle of a function.
I tried resetting the NVRAM and the PMU to no avail. Now it's not only the blue screen. Sometimes I get to my desktop and it freezes, sometimes there's a black screen, blue screen, black screen lines with white lines, sometimes a Greyish background with a black box. Also, do note that sometimes the iBook freezes at the open firmware command prompt (Option+Apple+P+F). Overall, I can say that it freezes randomly.
However, target mode works perfectly. I can access and open my files with my desktop mac. It doesn't freeze or anything. It just seems to freeze when I startup or use the boot CD.
So does anyone know anything else I can do? This happened two months ago, so I bought an HP (

) and kinda gave up on the mac. I also noticed some "yellow burn" right at the exit of the fan, right under the iBook G4 logo at the base of the screen. I thought at that moment that my logic board fried, but maybe it's not that after all.
I'm hesitating between going to a Mac Repair shop, them charging me 50$ for an evaluation and telling me that it'll cost 600$ to repair the motherboard, or just selling the mac for parts on eBay...
What do you think?
