Hi Tomshardware

I have just finished assembling my first computer. But when i try to boot it the following happens:
Case light turns on, then turns off after a second
A second later, it turns on again, but nothing shows up at the monitor. It doesnt even indicate that it is connected to the pc. Everything inside the pc seems like its on, though. Though i didn't install an optical drive yet (as i lack the cables), the mobo should show the bios anyway, shouldn't it?

I have no idea what is causing this, and i would very much like your help
 
Solution
Assuming that the monitor is just black but not showing the "No Signal" screen, check the 2 power supply connections on the motherboard; 8 pin and 24 pin.

Well the thing is, my monitor just blinks as it does when you have not powered the pc on yet (when there is absolutly no signal)

Are you connected to the discrete GPU cards or the intergrated graphics? It may just be that Bios is using your integrated graphics instead of your GPU cards.
