For the last two days, when my computer is first booting up in the morning, the display lights up then goes black. This happens every few seconds until the entire process is finished and then the display stays on full time. Does anyone have a clue?? I'm using an Acer mother board, Princeton 19" flat screen monitor and MS windows xp. When I went into the control panel this morning, and checked the various tabs in display, I did discover the desktop tab showed "azul" as the option, but the monitor in the tab was black. I re-set the option and the correct desktop came up... Is there any connection? Norma
