Display doesn't light up with a wireless card installed.

I am working on a 15" Macbook Model #A1150, after installing this wireless card. The machine starts and runs perfectly with no card installed. The strangest part is that it seems every time to fail in a different way. Here are the most common failures.

Boot failures so far (with card installed):

- Does not boot

- Boots, and remains on with no display out

- Boots, no display, shuts down ~10 seconds into start up

- Boots, working display, shuts down ~10 seconds into start up.

Attempted fixes so far:

- Different, known working, Left I/O Board

- Different, known working, Wireless Card

- Different, known working, 85 Watt AC Adapter

Thanks.

If the I/O board and wireless cards are known working, check the I/O board cable too.
