When it keeps turing on and off, I can see the windows screen - so the system boots up ok. Its the monitor that keps turning on and off. Once it stays on, the monitor works fine.
The moitor did not come with drivers, it uses generic driver. I have resinstalled the monitor drivers just to be safe. But it didnt help.
LiquidVideo is a Circuitcity brand, there is not much documentation avl - like specs, users manual etc.
