From way you've stated it does sound like your GPU card is failing. Here's the part info for the replacement part. Bars tend to be bad Video RAM so you'll likely need a new board

* 2007 24” iMac Video card
** 661-4426 ATI Radeon HD 2600 Pro, 256 MB 
* Early 2008 24” iMac Video Cards
** 661-4663 MXM III, M76XT+/256MB GDDR3 
** 661-4664 MXM III, G92GT+/512MB GDDR3 (CTO) 

We don't have IFIXIT guide for your system, but this one will get you there: [guide|5214]

You'll need a good thermal paste for the GPU and you'll need thermal pads for the RAM chips after you fully clean the old thermal paste & pads when you re-mount the heat sink.
