How did you capture this on video? Does it do it at the same spot all the time? or is this a small clip from a larger video?
I ask because I've had this problem with my setup - Using DP7 - for over a year now. It sounds just like your video, but since it happens to me every few hours, and so quickly, I haven't every "Caught it" in action..
I've done everything to try and solve this and nothing has prevailed. I bought all new RAM, all new hard drives, re-installed Mac OS X, everything! Except buy a new computer..
Let me know if you solve this. I'm willing try anything!
Do you think it could possibly be a bad part of the mother board? like where the RAM fits into? Anyone that tech saavy to know if it's possible?
Good luck!
