Hello RJ...
I think you mean the ASRock ION 330HT?
I have on of last year's version, before they stuffed in wireless and infrared, but it's basically the same Mini-ITX board as yours. I had the same stupid problem with Win7... What's likely happened is that your Video Memory has been de-allocated in the BIOS...
For me the fix was to go into the bios (Press F2 during startup) and load the bios defaults, save the settings, power down and then let it start up again...
There's a bunch of overclocking and voltage settings in there that probably shouldn't be user accessible. I've played with them but always end up back on the Bios Defaults to get it stablized.
Of course in the end I went back to XP in that machine and it's...
