Monitor Randomly Shuts Off

Hey all, I have an odd monitor problem.

I have a HANNspree HF237 monitor hooked to a GTX-570 via DVI cable.

Starting yesterday, my monitor will randomly go black. But the LED light near the power button stays blue (blue means it is powered on and receiving a signal, and amber means no signal).

If I turn the monitor off and then back on, it will show my screen for about 2 seconds before it goes black again, but the LED still stays blue.

If I restart the system, the problem goes away, at least for a little while.

I tried hooking up the DVI cable to the other DVI port on my GTX-570 and that did not solve the problem.

I purchased this monitor in December 2009, so it is not that old.

I did not update any drivers or anything else since yesterday.

I am running a Core i7-975 with 12GB Corsair Dominator and an Intel 320 series 120gb SSD. My GTX-570 was made by Galaxy and purchased in December, and has worked flawlessly since then. I have never had a single other problem with my system.

It seems like I might need a new monitor, but I wanted to rule out anything else before I go spend $200 on a new display.

Thanks.
