How to clear up the memory buffer on my nikon D60?

My Nikon D60 froze up on me last night and it won't autofocus because of the memory buffer being almost full. I know i can't actually do it myself (no such action on the camera exists) but what should i do to get it back to normal? Can it get back to normal?

I tried changing settings, changing lenses, reseting it and nothing has changed.

Have you tried removing the battery and letting it sit idle for about 30 seconds before plugging the battery back in? Have you tried using another memory card? The buffer are used to 'store' the image before being written to the memory card. If it is full, then I would guess it was the memory card's fault.

Cameras memory buffers to NOT stay full. Once the buffer has written image files to your memory card, it is empty and ready to buffer more images. The butter is only needed if you are in the habit of machine gunning your subjects.

If you use shot discipline, your memory card should keep up with your shooting speed, no problem if your memory cards are Class 6 or faster.

Remember, you need to copy all your image files from your memory card at the end of each shooting day and once they are safely on your computer, the card needs to be formatted using the format feature on your camera. When was the last time you formatted your memory card(s)?

The memory buffer is volatile memory; meaning it is erased when the camera is shut off.

If you are having issues where the memory buffer fills up after taking a couple of photos, then your SD card may not be allowing the camera to write to it. This could indicate a problem with the SD card, and simply formatting the card or replacing it may correct your problem.

Otherwise, you may have a hardware issue with your camera.

Turn power off.

You have no control over it but you can make it clear up faster by using a Class 10 SDHC memory card with the camera. Also remember to format the card each and every time you begin a shoot or after you copy all contents to the computer.
