Have you checked all the software updates and installed all of the available ones? especially the EFI firmware? Check the EFI firmware version on your system and verify that is the latest from this link. http://support.apple.com/kb/HT1237.
If the version is not right you need to install the software updates and restart the Mac. After installing the firmware updates install the Boot Camp drivers again.
Also I know that you had tried most of the possible stuffs to get the issue resolved. However if you haven't tried that please try this.
1. Boot to Windows in Boot Camp
2. Right click on My Computer and select Manage
3. Check the display drivers installed
4. Right click on that and choose to update driver
5. When the wizard comes up let it search for the drivers first
6. If it is not finding the appropriate drivers repeat the steps and choose to install from the disk
7. Insert the Boot Camp driver disk (i.e. Mac OS X install disk) and try to update the driver.
This should update the drivers for the graphic card and the issue may be resolved. If the issue persists, please run an AHT as there may be an issue with either the Boot Camp drivers in the DVD or the Card itself.
You will need to contact the Apple store for a different disk and try installing the Boot Camp drivers or analyzing the Graphic card issues.
Hope this helps you......

Best way to play windows games on mac 2017. How much faster is the graphics performance of the 'Unibody' MacBook Pro when using the NVIDIA GeForce 9600M GT compared to the NVIDIA GeForce 9400M?
Please note that this Q&A specifically refers to the 'Late 2008/Unibody' MacBook Pro models although subsequently introduced MacBook Pro models with dual graphics systems also provide significantly better performance while using the 'dedicated' graphics memory rather than the 'integrated' graphics (which shares memory with the system). This Q&A is up-to-date and is quite useful for anyone considering one of these models on the used market.
The 'Late 2008/Unibody' MacBook Pro models have both a NVIDIA GeForce 9600M GT with dedicated GDDR3 SDRAM and a NVIDIA GeForce 9400M with 256 MB of DDR3 SDRAM shared with main memory.

The NVIDIA GeForce 9400M conserves battery life, but provides inferior performance. With general knowledge, one would expect an 'integrated' graphics system that 'borrows memory from the system' to be substantially slower than a graphics system with dedicated memory, but how much slower only can be unveiled with real-world tests, and most dramatically with games.
Third-Party Graphics Test Results
In a series of gaming tests, MacWorld found:
On the new MacBook Pros the frame rate performance takes a dramatic leap when switching from the 9400M to the 9600M GT. In Doom 3, the frame rate more than doubled when testing at 1,024-by-768, and nearly tripled at 1,280-by-800. In Quake 4, switching from the 9400M to the 9600M GT resulted in a gain of 20 to 30 frames per second. In Unreal Tournament 2004, the gain at 1,024-by-768 is modest, but significant at 1,280-by-854.
As part of an in-depth review, ArsTechnica also hit both graphics processors in the 'Unibody' MacBook Pro with a test in Spore:
First, we set the machine to use the integrated GeForce 9400M graphics and loaded up Spore. We cranked the detail settings to the maximum and ran the game at the LCD's native resolution (1440x960). For the next 15 minutes or so, we played through the game's first phase -- an essentially 2D experience where one swims through goo while attacking smaller creatures and avoiding getting eaten by bigger ones. This portion of the game play was extremely fluid and there were no delays or slow-downs.
The 9400 showed its limits however, when the game entered it's second phase. Our creature, quite literally, crawled onto land and we entered a world of sluggish video. The 'creature phase' takes place in a much more complex world, with depth-of-field, many 3D characters, and a whole landscape to interact with. . . maximum quality levels at this resolution on the integrated graphics was simply too much.
Next, we switched the computer over to the discrete GeForce 9600M GT card and turned all settings back to their maximum. The 9600, in contrast, handled everything Spore could throw at it.
For Windows games, the MacBook Pro is limited to using its GeForce 9600M GT graphics processor, so there is no other way to test the GeForce 9400M without using it on the 'non-Pro' MacBook. Consequently, the Gizmodo blog did exactly that in a 'Hardcore Graphics Death Match' and concluded:
Pretty gigantic gap in Crysis performance here. It's a bit more than the 50ish% difference tossed around a few weeks ago when describing the 9600 vs. the 9400, but that's also due to the faster CPU, more RAM and increased L2 cache found in the MacBook Pro. Still, though, you can gauge from the two charts that Crysis is kinda playable on the MacBook on low, and playable on the MacBook Pro on medium. Both are chunktastic on high, and both get slower when you start shooting people in the forest.
Performance Summary
Chunktastic, indeed. Ultimately, the performance of the GeForce 9600M GT is massively superior to the GeForce 9400M, which is best reserved for use when battery life is more important than performance.
