To assist in planning possible diagnosis, could I ask that you define the port/adapter/input configurations for your monitors, and clarify that it is not just one monitor or one port that always has the problem. This being so, is it always the same one for a given configuration, or can it randomly be any monitor for a given arrangement? If one starts showing the problem at a given time, will it continue to be only that one for that operating session?

So my graphics card has 5 outputs: 1 DVI out, 3 DisplayPort outs, and 1 HDMI out (that mirrors the last DP port).
I ran DVI directly to one of the monitors, and used three DisplayPort>DVI adapters to run DVI to the other three. It's always a DisplayPort monitor that has the problem.
I'm able to plug 3 monitors into any configuration of three ports with no problem, but when plugging in a fourth, that's when the problem arises. For example, my ports are laid out like:
   
1 being DVI and 2-4 being DisplayPort. I have monitors A B and C plugged into ports 1-3, and when I plug monitor D into port 4, the problem starts. I tried plugging monitor C into port 4 and it worked with no problem, but when I plugged monitor D into Port 3, the problem started again. I also tried only plugging Monitors A B and D in to see if it was a monitor problem, and they all worked fine until I plugged in monitor C.
Hopefully that made sense. And it used to work temporarily before going out, now if I plug it in it just immediately starts doing the connect/disconnect thing.

If it's the last one being plugged in that causes the symptom, is it that one that has the problem? i.e A, B & C are OK, plug in D and D has problem. A, B & D is OK, plug in C & C has problem.
Are the DVI adapters just passive adapters, not a converter with power?
Being only the DisplayPort having trouble, I wonder if a less than ideal driver has got installed? Is Windows Update set to install both important and recommended updates or only important updates?
Would you mind publishing a Speccy system report?
Another thought is, to work out if the problem is some strange quirk of simultaneously using 3 DisplayPorts through converters, drive one of the monitors from the HDMI out through a HDMI-DVI adapter/lead.

It's weirder than that. I just plugged in B, and B came on, but C went out instead.
The adapters are passive, yes.
I just went into Windows update and saw a driver update for my monitor, which I got really excited about, but even after installing it, the problem persists.

I'll try to pick up an HDMI/DVI adapter and see if that helps.
Thanks for all your help so far! Let me know if you need any more info from me.

Driver updates sourced thru Windows Update can sometimes cause a problem, which was what I wondered about. However there seems to be no indication of a random video driver update, and MSI link to default GeForce WHQL drivers for their products anyway so there shouldn't be a problem there.
There have been a couple of video driver version releases since yours, so you could try the current release if you wish, in case your effect was a bug that's been addressed:
Yours is Driver version: 10.18.13.5582, latest is 10.18.13.5887
Under Windows 7, monitor detection is performed by Windows' own CCD (Connecting and Configuring Displays) API, so it could be worth running a check on system file integrity:
Before you look at potentially making any alterations to the system, do you have adequate system backup - any system partition image or similar? Apart from this just being good safe practice for an important computer, it can be useful if something annoying goes wrong during maintenance. For example, as per release notes, GeForce video drivers do not support rollback thru Windows restore, or removal through Device Manager. It can only safely be done thru Add and Remove Programs. If a video driver install becomes horribly corrupted (remote chance but not impossible), a good system backup can be a godsend.
