PSP tunrns off by its self

My psp turns off by its self but when I flashed the flash1 it didn't do that anymore what was wrong with it?

 

it still does that

 

Have you tried reinstalling CFW?

That saved my ass plenty of times.

 

no

 

Also try with no games on the memory card, a bad game can cause the PSP to shut down completely as soon as you try to view the game in the menu

 

Yea but when I have the charger in the psp it does not do that at all.

 

Then change the battery, the batteries have a circuit board in them and can cause strange happenings when they are faulty
