Record screen in a loop

[Shpaget]

I'd like to record the screens on a PC since a program I'm running acts up a bit every once in a while (sometimes entire day goes by without a hitch, sometimes I get two problem in an hour and then nothing for a week).

The thing is, the program takes up 3 1920 x 1080 monitors and there are a bunch of tiny numbers all around, which I'd like to be able to see in the recording. Good news is that I only need about 5-10 minutes worth of footage to satisfy my needs. The bad news is I don't know when the problem is about to occur, so I'd like to record continuously.

Since I would not like to burden the PC with any unnecessary tasks such as compression on the fly, my thinking was to have the screen recorder overwrite old footage as to not consume insane amount of storage. Is there a screen recorder that can record 3840 x 2160 desktop (there are two monitors in the bottom row and one on top of them) and loop through the recording?

Are you by any chance doing this?

 

3 monitors. Bunch of tiny numbers all around...

 

Sorry for the joke and no help (I have no idea about computer recording), but it just seem too perfect to pass by.

No, this is somewhat different. Tank has it easy.

 

As you can see, given the situation, my request to record only three screens is rather simplistic. The three screens I'm interested are in the bottom row, third and fourth from the right and the one above them. The one above them is actually only a bonus. If all else fails, I can do without the image from it and will be happy-ish with just the bottom two.
