Graphic Card problem or Motherboard Problem?
Since 2 days ago my iMac 24 has graphical problems.
Everything else works fine, but when there are elements that require the graphics card for 3D, bugs happen.
The bugs are similar on Windows and Mac
For over 4 years, it has never caused any problems.
iMac 24' Early 2008 (EMC 2211)
3.06Ghz Intel Core 2 Duo
NVIDIA GeForce 8800 GS 512MB
4GB RAM DDR2 800Mhz
500GB HD Western Digital
Mac OS X 10.6.8
Windows 7 Ultimate 64Bits
The bugs are the following:
- fixed windows
- 3d objects twisted
- black areas
- textures bugs
Here are some pictures and videos for you to realize the problems.
I made several tests:
- Update complete
- Reduce the resolution to minimum
- Apple Hardware Test (AHT) [no problem found]
- Test several resolutions
- Disconnect the secondary display
- Testings with Windows
A copy of the last kernel panic:
The problem remains constant. The problem affects everything in 3D. I wonder if the problem is with the graphics card or motherboard.
In my opinion, the problem is the graphics card.
Is there a way to fix this problem? Do I need to perform more tests?
At worst, is there a website or a shop that I can count on to buy a graphics card new or used?
Thank you in advance for your help and answers.
