The screen actually turns on and works for 10 seconds before turning off. Everything is plugged in correctly, there doesn't seem to be a problem with any cords, my computer is definitely capable of running it... Support hasn't replied and it's been a few days.
It's not video card that's at issue - as seen in the compatibility check that's OK. The software doesn't recognize the processor (CPU) in your system - what is it? Do you have an unusual processor/MB in your system?
