When you navigate through the XMB does your PS3 glitch and then freeze? Not doing anything else, just moving through your XMB.

I've tried this 5 times now, and all 5 times my screen flashes and then goes black. I have to hard power off the system but when I plug it in again it works fine...til I move around the XMB some more.

Anyone else with this problem?

EDIT: Disregard all that now. Found a thread that got bumped, didn't find it when searching though :/
