BB Bold 9000 :: White Screen, Red/blue/yellow Pixels

There seems to be a problem with my blackberry or my blackberry's screen.

Sometimes when I click any of the buttons to wake up my screen to check if I have messages/make a call or what have you...

1. The screen is black white and stays that way for a few seconds before reverting to the normal screen.
2. The screen is covered in static similar to a television except it isn't moving, and the pixels are red, yellow and blue. This either fixes itself after I unlock the phone, or it only fixes the part of the screen where the box that says "keypad is locked" is usually located, and then goes back to normal once I press another button. This happens sometimes even if the phone isn't locked, and if I have a text message open I can roll the type cursor back and forth and that part of the screen will be fixed again.
3. The screen is white, but the red/blue/yellow pixels wash across the screen from left to right, and once I press a button it fixes itself.

It's a Blackberry Bold 9000, only one year and one month old, and at&t is my provider. I'm not sure if it's a coincidence, but the problem seems to have started around the time I put a memory card in it.

I have tried taking the battery out of the phone and putting it back in. Nothing changes.
