Bad graphics card on an Intel iMac?

My intel iMac is displaying vertical lines (20-30) on the screen.  The Genius Bar guys saud that it was the graphics card.  My question is whether this is totally separate from the motherboard?  I plan to  buy a used iMac with a dead motherboard and take the graphics card out and put it in mine.

    While that may be true, it gets me no closer to an answer.  Does anyone know of a source of information on the replacement of the motherboard or the video card?  Can I use a video card from a G5 as a replacement?  I have lots of questions, some ingenuity, but I need help...

    Strange lines on screen. tech Tools Pro, however, does not detect anything wrong with the video card. The symptoms match a bad video card, however. I'm looking for a link showing video card replacement on an Intel IMAC video card.

Lines on an iMac are usually a sign of a bad monitor not video card. The technicians at the Genius Bar are anything but genius.

It is most likely the video card, and I though Mac's didn't have any issues?

Monitor gets striped display


Hello did you install the graphic driver ???
If not download the driver here for your windows system:

http://www.asrock.com/mb/Intel/G41M-VS/?cat=Download

Please check the screen cable for loose connection.
Check also the screen on another pc for fault.

If a external graphic card is installed, visit the graphic cards homepage for downloading the driver.

Try also to look in the device manager for any drivers missing.

Good luck

Thin yellow vertical line


Linear defects of this sort can be caused by a faulty display cable, a faulty LCD panel, or a faulty connector between the two. Much less likely is a problem with your graphic processor, since the line is static in appearance and position. Unless your Mac guy has lots of spare parts hanging around, I would suggest you replace the cable first, as it is the least expensive fix. If that doesn't do the job, then the display panel must be replaced.

White bar on right side of screen


Try a reboot. If it remains, shut down and leave off for about an hour. If it comes back you probably have a problem with your video card. You can have it replaced (it will be pricey though), or consider getting a new computer. I had a similar issue with an Intel iMac 24-inch out of warranty and had the card replaced but your machine is much older.

Vertical line in imac 17" core 2 duo intel 2006 model


Attach an external monitor (you may need to buy an adapter to try this) and turn on Display Mirroring in the Display preferences.
If the same symptom shows on the external monitor, then you've got a video card problem. If not, I'd say you're screen has some kind of damage of failure.
Sorry, but either one is likely going to require a trip to the Apple Hospital.
At least with the display problem, you could use the external monitor until repaired.

Graphic card problem.


Your graphics card is bad. The reason you don't see it on your bios screen is because it is not displaying in the high resolution high color graphics. Once your card starts displaying high resolution high color, then you get the lines. You need to replace your graphics card.
