I recently purchased a Dell OptiPlex 755 computer and am having a mysterious power on issue. Although it came with 32 bit Vista Business, I installed the 64 bit version. Ever since I've had the computer (approximately 1 month), the following issue occurs (not everytime but frequently):
This is the strangest thing I've seen. Admitedly, I have not yet contacted Dell as I have tried to figure out the sequence of events that consistently puts the machine in this state.
I welcome any and all ideas regarding this matter.

this happened to me as well but it stopped as time passed... couldn't figure out the underlying cause.
