Psp problems

My PSP can not read discs anymore.When I put the UMD in my PSP it keeps making a buzzing sound.After like 20 minutes it says the disc can not be read.Why can't my PSP read discs and how do I fix it?

My wii does that to I read the booklet it said thatt it probaly needs cleaning. Try looking at your PSP booklet

Uh huh.

I've had this problem before
turn your psp on
leave it alone till the battery goes out
then get the charger
put the cd in
then put the plug on the psp so it will start charging and if you have like auto start (if that was on psp) then the game will automatically start

I'll try that.
