I just built my first pc and went to plug it into my Samsung tv. At first I tried HDMI. No luck. I tried another HDMI cable too and still nothing. I just went out and bought a DVI-D to HDMI cable for £23 and it still displays nothing. When I turn the computer on, all the fans on the build spin and the LED's light up. I can hear the optical disk drive starting too, but I can't hear any beeps. I think that my speaker may be broken. At the moment I have the DVI - HDMI cable plugged into the GPU and the other end into my TV. I haven't tested it on a monitor yet. I have checked everything multiple times. The GPU's LED's turn on and the fans start to spin. I have tried taking out the graphics card, using only one stick of RAM (would use 2x4gb) and all the cables are connected for all I can see. I am really stuck and I'm not sure what to do. Please help :)

While getting the black screen, if pressing F10 then Y or Enter, does the PC restart?

Nope. It stays as it is.

Can you borrow a monitor just for testing?
Attaching an internal case speaker to the motherboard would also help.

I have just been to my uncle's house and borrowed his monitor. This time I used a dvi-d to dvi-d cable but still nothing happens. I have a speaker on my motherboard but a wire came loose so I put it back in and I'm not sure if the speaker actually works.

If starting the board, only CPU and CPU fan installed, are you getting beeps?
What motherboard, CPU, power supply and graphics card?

CPU: AMD FX-6300
GPU: Asus AMD R9 270X
PSU: Corsair CX500
Mobo: asus M5A78L-M

As for the first part I am not sure. I will have to try it with only the cpu and cpu fan installed later on. I don't hear any beeps when I turn on the system on with all the components installed, but I do think that my speaker is broken. I shall see if I can pick one up from Maplins or somewhere later on and try it out.

The CPU requires the 1401 BIOS version. Is it a new board? There's a thin bar code sticker on the motherboard. What are the last 4 digits on that sticker?

The last 4 digits on the sticker reads '1503'

Then the CPU is supported. Let's wait until getting the case speaker, start the board with only CPU and CPU fan and see if getting 1 long 2 short beeps.

Just a few questions:

Do I take out everything but the cpu and heatsink including fans, hdd etc or are there some things I leave connected
Do I connect the build to a monitor or not and just listen out for the beeps?

Remove everything but CPU and CPU fan. Leave both 24 and 8 pin power cables and the CPU fan wires connected to the motherboard. The case speaker connected too.
Start the board. The CPU fan should spin and the speaker should get 1 long 2 short beeps.

I found the solution! It has something to do with the CMOS battery:

1ST. TAKE OUT THE BATTERY
2ND. WHILE IN THIS SITUATION (WITHOUT BATTERY), POWER SYSTEM ON.
3RD. SET DATE AND TIME IN BIOS
4TH. POWER OFF SYSTEM.
5TH. INSERT THE BATTERY.

END.

SYSTEM STARTS UP
HOPE IT HELPS!
