550D SD Card problem

So i recently flashed magic lantern 1.0.9 for my Canon 550D.

When i was recording a video it flashed something like "EXT SD CARD..." and then it quickly switched off. Since then, it functions normally without an SD card inserted - LCD, viewfinder and shutter works fine.

However, when i insert my 32gb class 10 sd card, the LCD of won't be able to turn on. The viewfinder works normally but i am unable take a picture/trigger the shutter and a green dot on the extreme right of the viewfinder would be blinking instead.

I tried reformatting my SD card via my laptop but it still is the same.

It actually happened once before when i was doing a photo shoot outdoors. Before i even flashed magic lantern. The camera displayed "EXT SD CARD..." and it turned off shortly after. I actually left the camera aside for a couple of weeks and it returned back to normal.

Does anyone know the solution to this problem? I don't think magic lantern might really be the cause of it. Maybe the card reader is turning faulty?
