Monitor blinking on startup

  1. I'm working as a student assistant at my university. The computer that I use at the desk there is a Dell GX 280. When I start the computer, the monitor works fine until I reach the login screen with the "Press Ctrl+Alt+Dlt" box, at which point the monitor goes black for a second, then returns, then goes black and so on. The monitor power button remains green throughout the hissy fit. This can last anywhere between five and ten minutes, regardless of if I log on or not.

    Considering that the computer belongs to the university, I can't take it apart and look around inside. Despite this, if the problem most likely involves hardware, I can notify someone to (hopefully) replace it. What do you all think?
