Just to make sure, you have cycled through all the various input signals while the machine is running, aye?


Have you switched the cable out yet, or tried a cable you know works?


If you have done the previous two, have you tried a different video card? Does the machine post with an error code (certain amount of beeps)?


Point is, it's difficult to suggest corrective measures with this little information.

Sorry for the short message first of all.

What I have tried connected with all new built items above:
- no beep sound detected
- motherboard is running because it got an switch to the board that I use to turn on and off. Asus z97-deluxe
- tried with old graphic card - still giving no signal detected from the monitor.
- is an old monitor benq xl2411 - still can run on my previous pc - DVI cable checked ok.
- new power supply Corsair RM650 with correct 6+2 pin connected with green leg light up on graphic card Asus Geforce Direct CU II 2GB

Will try later:
- inboard graphic with Mini DisplayPort to DVI to my monitor - need to get one later
- unplug everything except motherboard, graphic card, CPU to power supply later.
- unplug CPU and reinstall again

I recheck my motherboard, there are two power supply that we need to plug into it.
- single 6 pins power supply to support CPU
- combined 20 pins power supply to the motherboard itself.

That's actually already solved the black screen that appear on my monitor. :)

However, the motherboard came in with built-in graphic card which you need to plug in the DVI-D cable or Displayport cable (depending your monitor type) before you starting to set up your separate graphic card. Note, cable need to plug into the motherboard built in graphic card, NOT the separate graphic card you installed.

Install your separate graphic card's software into your computer.

After the software installation,
- click start menu, type msconfig
- click on boot tab, click on safe mode, keep it in 'minimum'
- click apply and ok
- restart later
- right click on computer icon to find device manager
- find display, right click on and then disable VGA or the built in video graphic
- click yes, Do not restart
- click menu and click on shut down instead.
- unplug DVI-D cable and plug into the separate graphics card you got

- turn power on your PC
- once if you successfully gone into your window, go to menu tab, type in msconfig again
- click on boot tab, unclick safe mode, click apply and ok.
- restart computer and once you back to window, it should works!

Good luck to you, otherwise you need some troubleshooting.
