HTC Touch Pro 2 is constantly crashing

[Kenaf]

I've had this phone for awhile now, and I was playing around with it yesterday (Friday) by loading up Android on my SD card. This is a Sprint HTC Touch Pro 2. I've loaded up Android before and it was fine, I was just trying out new versions/kernels. Anyway, I got Android up, and I was trying to get 3G going, so one of the things I tried was removing the SIM card and putting it back in.

I'm not sure if it was loading up Android or removing the SIM card that did it, but ever since my phone (in Windows) has been crashing constantly. It just suddenly shuts off. It seems like it mostly happens whenever I slide out/in the keyboard. I've tried taking the SIM card back out and its still crashing constantly. I did a hard reset on Windows (to factory default), thought for sure it would fix it, and it didn't, its still crashing. Did I manage to screw something up really badly? I don't think its Windows anymore since the hard reset didn't work, the only thing I can think of is maybe I broke something when I removed the SIM card.

Thoughts?
