Reboot/Freeze(2 problems in 1)

ok my problem is that wenever i got to home menu in a game and decide to end the game i can select end. but as soon as i do it freezes my psp.i then hold my master power button till it turns off. this is where the second problem starts. Wen i manually turn my psp back on with the power button it turns on but doesnt load up UNTILL i hold the R button then it goes to recovery mode. then i exit recovery mode and the psp loads up fine.
how do i get the psp to load up without goin into recovery mode? and how do i get my psp to stop freezing aftet i select home and end game?
