WTF BB 9900 no red light, no nothing

I started to have random memory card errors and phone wouldn't ring(it wouldn't play the ringtone) last week. It would be fixed by alt+shift+del but I got myself a new memory card today and moved all my data. In order to change the memory card I took my battery out (not hot-swappable thx to RIM) and put in the new one. Now 9900 is completely dead. I mean no red light no nothing. I tried to reload OS but pc won't recognize it despite whatever I do.

Do you guys have any suggestions?
