I recently moved to the USA from NZ. I brought with me my hard drive K&T Pro2(MS-6330) ATX VA Motherboard. I decided not to bring my monitor across with me (too costly). I bought a monitor here in the USA which works on US PCs (tested). For some reason it will not work off my hard drive. Could it be the power supply? Graphics card? I have checked the cables (US); monitor and power supply. Appreciate any assistance.
