Memory overload

I got a sansa fuze 4GB. Lately I’ve been converting videos a lot, and once, when i unplugged, the screen gone all white…I’m pretty sure that i overloaded the memory.The usb device is not recognized, and i dont know how to remove the videos now x.x…Anyway, the screen is all white, and memory overload or not, ill be very glad if someone knew how to fix that.

Disconnect it. Hold the power button up for a full 30 seconds, well after the screen turns off.

See if it’s reset itself. Often it does.
