Have any plugins installed? Or are you using a UMD?
The Power Manager plugin for example L+[] will shut down the psp completely.
I have the XMB custom theme plug in and PSN enabler plugin enabled. I've disabled them then try play the game but it still goes to a white screen for a few seconds then shuts down; whether they were on or off. And I'm playing it from an ISO

QUOTE(Bowser-jr @ Feb 18 2010, 06:40 AM) Okay, I'll be playing story mode and after a i beat a chapter/part it will go to a white screen and then shut down. This happens every time I play story mode. Could someone please tell me how to fix this problem?
This happened to me once. Every time I defeated Chaos in FF2 story, the same happened in an Unmodded PSP with 6.00 OFW.
I you saved before the battle with chaos (that was my case) then you'll need to restart the entire chapter or history.
