Alright, so I've got this problem with my PSP, it always shuts down after a few minutes of being on. I doubt its a system problem, it's not a memory card problem, not a battery problem (tried 2) which work on my friends psp. I've tried a lot of things and tests and I've concluded that this thing that started happening recently, my UMD drive is going all crazy, there's nothing in it i've turned all the system settings concerning UMD's to off or none. It started doing this thing where every time i turn on my psp the UMD drive starts doing something. I can hear moving noises, like when you actually put a UMD in. Something is moving inside the drive left and right stopping for a second and spinning or something. I've never had that happen before, but now it happens every time i turn it on. The psp also stopped working when that started. It's kinda like that action which the UMD drive preforms, tells the PSP to shut down in 5 minutes, and it always shuts down in the same timeframe too. Does anyone have any insight on this? I'd really appreciate help.
