Yeah, it's possible if the monitor is getting a signal that is all black. This means the monitor is probably working, and the video card is at least half-working.
This sort of thing will happen if a device is drastically misconnected inside the computer, or has died. I've seen a similar boot sequence when a CPU fan died, except on that one the speaker kept beeping.
Hate to be the bearer of bad news about this situation, but unless it's under warranty, or it turns out to be something obvious once you open it up, it may be time to just get another PC and transfer all the stuff over - if the hard drive works, they might be able to install it in a new computer and run a repair installation on the Windows install and get it running again so they don't have to reinstall everything. I say this because the time to diagnose and fix what's wrong, including whatever parts are needed, is most likely going to cost more than a comparable computer.
