Screen Flashing

I have noticed over the past week which at random, when my screen saver starts, instead of starting, the screen will just start flashing/blinking/pulsating. I can see the desktop, then it goes black, then desktop, then black, really fast (maybe 30-40 times per minute). It doesn't happen every time, so its not like I can walk into the Apple Store and show it to them. The unit is under AppleCare, so what is going on? Video card? Bug?

Anyone????

Sounds like your system is having sleep issues... Is this an older machine?
If it's under apple care then they are the guys to talk with about it for sure.

It is listed in the profile at left. It's not an old unit. MBP 2.4 with OS X 10.5.6.

Anyone?
