Check what BurnUnit said, try turning it on without the SD card but in any case use a full size SD card. Replace the battery with a new Canon made one

Ok, how old is your battery? The least expensive solution to try is a new battery. Even though yours might indicate a full charge it may have lost its capacity and goes flat instantly when you boot up your camera.

I kind of doubt it, but how about the battery and memory card door switch? Try putting a little extra thumb pressure on the closed door when you try powering it up.
