Hello all.

I have just built my first PC. I have followed the steps found in a post on this website. I have then tried to boot it but my monitor doesn't get any signal from my PC.

I have tried the steps found here (http://www.tomshardware.com/forum/261145-31-perform-ste...) but it didn't help.

My system speaker beeps once, my graphics card is powered up (the fans are spinning), I'm really hitting a wall here, I have no idea what do try next.

Here are my specs :

Are you sure that no pins in the motherboard are bent?

Are you sure that everything CPU, cooler, ram, GPU and all power plugs are seated well?

Try removing one stick of ram and try 1 of them by itself in separately in each ram slot.

You can also try removing the GPU and connect to the onboard video to exclude the GPU from being the issue.

Also unplug one of the hard drives. Basically get it down to just the bare essentials needed to boot up and display video so you can start excluding things as being the problem.

How do you have it plugged in? to both the monitor and to the video card?

check to make sure that the monitor's settings on the monitor's menu is actually set to the correct input method, ie. HDMI or Vga/analog, etc.

Also, in your UEFI bios,Verify that the motherboard is set to look for video on the PCI-E slot and not the onboard video.

Hello bccorrupt. I have verified the pins and none appeared bent.
The plugs seemed okay. The CPU has lights turning on, the GPU had its fans on, the cooler fan is spinning.
I have tried removing 1 RAM stick and then tried with the other stick in all 4 slots but nothing different happened.
After removing my GPU (and plugging my monitor on the onboard video) and booting my computer, the system speaker made a second beep, slightly longer and lower-pitched than the first, occurring approximately 5 seconds after the first beep.
I have unplugged the SSD for all of my tests, leaving only my HDD plugged.

My monitor is still not receiving any signal.

I believe one short beep and one long beep usually relates to ram. Try the other stick by itself in a couple different slots. Also, you are aware that you will have to push harder than you think you would have to to seat the ram right? Make sure it is seated completely on both sides.

Hello all and thank you for your help. I have simply restarted from scratch and replaced every part. Now it is working, I guess there was something improperly connected somewhere.
