My psp has been running GREAT for months... running DAX 3.40 OE with a 4 gig memory stick... Starting 2 days ago it just freezes.. whether it is playing an ISO or a UMD or just scrolling through the menus...I can leave it off for a bit and it will be just fine for a little bit.. then it suddenly freezes again. I tried putting in another memory stick and it still freezes... I am SERIOUSLY starting to pull my hair out... Anyone got any suggestions??
