My mid-2010 Mini works fine, but lately my dual Dell monitors have started going blank at the same time. The only recourse is to power down the Mini and restart and the monitors come back fine. This has happened twice just today. A few months ago I went through a period where one monitor would go blank. That seemed to cease, but now both will go blank at random times.
Any updates on this problem?

First try resetting the NVRAM / PRAM, as per > About NVRAM and PRAM
Then what connections and adapters are you using..?
I have the same 2010 Mac Mini w/8GB RAM set up using dual 21.5" Samsungs DVI monitors. One is on the Apple Supplied HDMI to DVI adapter and the other is on a Kanex Mini DisplayPort to DVI adapter. I'm using the Kanex adapter, because I had nothing but the same trouble that you are describing using other Mini DisplayPort to DVI adapters including a couple of Apple branded ones.
