I would also like to note that this also only seems to happen when there's a program running. If the monitor is looking at the desktop, it doesn't blink at all -- As soon as I open ANY program, it will begin blinking incessantly.
Additionally, if I use a DVI adapter and use the standard cable, it also works fine -- So it's not the DVI output on my video card, that seems to work just fine.

You said you bought 2 2001FP's. Do you have them set up in dual monitor mode? If so, does each of them work OK in single monitor mode?
You may want to try this: Go into Control Panel>Power Options. Under "Power Schemes" set everything to "never". You can also set the system to not enter "Hibernate" mode by clicking on the tab and unchecking the box.
I've seen this happen under Linux when changing from 1600x1200 to VGA text mode (640x480) during shutdown. But as long as it's in a graphics mode it works fine.

No, they don't. If I use a the DVI connection at 1600x1200 in 16 or 32 bit mode, the monitor blinks continually. Both monitors have this behaviour when connected using a DVI connection. If I use the VGA connection, the problem goes away. If I use a DVI->VGA adapter the problem also goes away.
I've tried both cables supplied to me by Dell, and purchased a third, thinking it might have been a bad batch of cables, again, the problem persists.
This isn't a power mode issue since it's directly related to running at 1600x1200 resolution using the DVI connection -- Yet works fine in 1600x1200 resolution using a VGA cable.

If you got 2 monitors, you got 2 of everything else...Did you also try it using each of the 2 electrical transformers (the little black box that comes with the monitor)...Try that and if that doesn't fix the problem, you've pretty much eliminated everything on the monitor side of the equation as the source of the problem...I would then suspect a problem on the computer side of the equation, e. g., your video card. I no nothing about nVida cards, so I can't help you there.
I have a Precision 330 with Win2000 and FireGL2 (ATI) graphics. This was purchased about 2 years ago. I got the 2000FP a week ago and experienced a similar problem using the DVI connector (analog was quite horrible, btw).
I noticed that the problem was associated with a change in the location or size of bright areas on the screen. For example, moving a window with a white background or even scrolling within the window caused the screen to blank out momentarily, as though it were switching video modes. I'm guessing that somehow transient noise or spiking in the data signal due to movement of white space is confusing the monitor or card. Makes me wonder if the quality of the cable is contributing.
After a lot of toiling, including updating drivers, I found a switch on the video card configuration utility called Sync Polarity (in the Adjustments tab). There are two of them, one for horizontal positive and one for vertical positive. Unchecking these boxes fixed it for me. I also have "Enable Sync Control Extension" (in the advanced settings tab) turned on, but I don't know if this matters. No clue why this worked, but it did the trick. It hasn't blinked for over a day now.
Anyway, if I had any advice to give just play around with some of the video card's switches.
