I have a 900mhz G3 12.1 iBook, which I ordered in August 2003 through the Apple UK Store.
It has been running perfectly fine for the last few months, but today I took it on a train, which is where my trouble started. I opened the lid to wake it up, and used it for a few moments. After a minute or two, the screen flickered slightly and some lines appeared. Then, the whole screen started to fill with lines of odd colours! I promptly turned it off, folded it up, and put it back in my bag.
When I returned home, I plugged it into the mains, and powered it on. The machine started but the screen did not come on. I turned it off and tried again a few times, eventually the screen came on. It started to loads OS X, and then the screen filled with the similar lines, and the loading-gear stopped spinning on screen. I turned it off and tried again, with similar results.
I inserted the OS X install CD and ran the disk check utility from the install program, checking first the permissions and then a full disk repair. I then rebooted to find that after a considerable amount of loading time, it booted into OS X. After a few moments, however, the same screen errors appeared.
As a student of IT and an experienced computer user, I am completely baffled!! Can I fix this problem, or does it need to be returned?
