Never hurts to check that you plugged all your power cables into your GPU and have seated it properly (it happend to me a couple times when i was doing a lot of hardware swapping).

Another thing you should check is the bios to see what display it has set for primary (could easily not have the gpu as the primary display and therefore you're getting nothing on the screen). Have you tried also changing which slot you plug your monitor cable into your gpu, there is typically a primary and a secondary, which again can lead to this.

Do you potentially have more then one system hooked up to the monitor? I know when i had two desktops hooked to one monitor and the monitor was set to auto-select mode it would always toggle itself between the two whenever i restarted as they typically try to select the at the time active video signal
