hello, I know what you are talking about with the clicking, my psp does that some times to. My suggestion is, format the memory stick (after backing it up if you want) then put what ever programs that you want to put on it, and everything that you put in the seplugins folder. restart your psp and see if it still happens, if it still happens then you have a program that is running in the back ground that is crashing. go back to your seplugins folder and make sure you have every thing for all your programs in there, turn on your psp in recovery, and check all your setting. when my psp did this i had to restore the system completely, that worked in till I upgraded the cfw to 5.50 gen-d full, it then did the cracking and shut of, I then used the psp tool battery with a magic memory card that installed 5.50 gen-d full directly, this fixed it for me, and should let you use your go cam as well
. hope it helped
. if this didn't work for you, and you get it fixed tell us what you did to fix it.
