(System: PSP-1004 CFW: 5.50 GEN-D3) What happens is that when I turn my PSP on (from shutdown), the screen stays black, the power LED is green, and the memory card LED blinks in regular intervals (maybe half a second). However, this only happens sometimes. Other times, everything works perfectly fine. I usually just turn it off and on until it works. Another time, the PSP wouldn't turn on at all until I removed the battery. (happened only ONCE so far) I disabled all plugins and non-default configurations in the recovery menu. So far, it has not happened when I unplugged the memory card, but because it happens so randomly, its hard to tell whether or not it is at fault. The battery is an original Sony battery, the memorycard is a Photofast CR-5400 (genuine!) and two 8GB Sandisc Micro-SDHC (genuine). I would assume its the card's fault, but I don't know. Has this happened before? Sound familiar to anyone?
