My 17-inch late 2006 iMac running Mac OS X 10.4.11 has started having some display issues, that is, showing vertical blue lines on the left side of the screen. At the moment this only occurs at the log-in screen or sometimes when waking from sleep.

Is this a hardware or software issue?
Can I do anything to solve it?
Will it get any worse?

I was planning to upgrade to Mac OS 10.6 and add more RAM but if this continues I can't really spend any more money on it.

Any help is really appreciated.
