PC turns on but wont boot

You need to select the HDMI port that the PC is connected to by using a button on the TVs handset, the button should have Source written on it, make sure that the PC is turned on, press the Source button then select the particular HDMI port on the TV that the PC is connected to.

I think I get what your saying and yes it was the correct hdmi, my xbox was plugged in and displaying, then when I plugged that same cable into the tv there was nothing

With the HDMI cable from your xbox connected to the TV and HDMI port on the Dell, restart the computer.

When the computer is restarting if your keyboard has any lights on it watch to see if they light up and likewise watch for any LEDs on the Dell that may light up.

Only LEDS are on my keyboard and are the lights for caps lock etc. I plugged it in again and pressed those keys and none of their respective lights came on

Never said anything about pressing any keys, do you see the caps lock or any other key light up when you press the case power on button.

Also what about any LEDs on the PC itself.

Do the internal fans start up when your press the case power button.

The keyboard leds dont turn on, the case and cpu fan both spin, and when plugged in the gpu fans do too

Long shot and this only for testing purposes, put the add on video card back in and use the same xbox HDMI cable and TV HDMI port to see if there is any change.

[Alex15787]

Am I plugging it into the video card hdmi port or the motherboards one

[phillpower2]

Video card

[Alex15787]

Still no display

[phillpower2]

Not looking good this I`m afraid

Is the MB at Amazon here the same as the one in your PC

[Alex15787]

Yep, that looks identical

Thanks (y)

Reason I asked was because the board has a BIOS error speaker on it that will help us with our testing, the boards must be the same though.

Lets see if we can get any error beeps from the MB.

The following checks require the computer case to be opened so take the following safety precautions 1st, disconnect the power cord from the wall socket, press the case power button for twenty seconds or so to get rid of any residual charge in the system, take anti static precautions before touching anything inside, you can do this by touching a bare metal part of the case or PSU.

Remove the GTX 1070 from the motherboard.

Remove the RAM from the motherboard.

Connect the video cable to the TVs HDMI port and the HDMI port on the motherboard.

Connect the keyboard to one of the black USB 2.0 ports on the motherboard.

Connect the power cord, press the case power on button, post back and let us know if you got any error beeps.

[Alex15787]

So I need to remove all 4 ram sticks

There is a constant beep, I heard it earlier too when the gpu was disconnected but thought nothing off it
