Question Both monitors go black after computer being on for a few minutes

[Rancidtea]

I have two monitors, both only with VGA outputs. When I only have one of them plugged in, the monitor runs fine, no issues. When I have both of them plugged in, they are fine for about 5 minutes then go completely black.

Unplugging one and restarting my computer, it shows the asus start up screen but then is only turned on but blank. I have to open up bios settings, restart, then have my computer blue screen with an error, and restart from there to register my single monitor working anymore.

It is not a cable issue as I have tried swapping the cables over and having a single monitor still works fine, and I have tried clean uninstalling/reinstalling my graphics driver as well.

Any advice?
