PC only gives signal to the monitor every second time I switch it on! :S

[Stardusted]

My build is the one in my sig. Lately, I faced a strange problem. When I switch it on, there is no image showing, and the monitor led stays orange. I switch it off, switch it on again, and fixed.

That happens always, and always on the second power up it shows image, on the first not.

Plus, I think I noticed when in windows some slight, veeeeeeeery smooth alteration in brightness level like someone is gently lowering the lights for a second, slightly, and then, again really smoothly, brightness goes up again.

The above may or may not be my idea, since it is so slight It might be me.

Any help please? :/

1. Try clearing cmos and resetting bios to default.
2. Dynamic contrast w/ monitor?
