I just built up a new computer. The motherboard, fans, CPU, GPU all working. Motherboard no error signal. But when I connected to monitor(DP), it no cable connected. I tried another monitor with HDMI, but also no signal.
Is dit een goede vraag?

If you are sure all is working then BIOS is looking for incorrect video port as in VGA, HDMI, Display Port or DVI.
Depending on motherboard hold done the key for BIOS/UEFI.
It is <Del> on my Gigabyte one. Once in BIOS don’t use “Auto” for port but select the actual one.
That should do it. If not do the same on the monitor, as well, to manually match the port.
Funny, I was just having the same problem today. BIOS fixed mine.

I didn’t change the port cos I couldn’t find it. But going into bios and exiting fixed it for me.
How do you go in bios if you have no monitor?
How do you go in Bios if output doesn’t work ?
Hi @iphoneapple
Turn off computer. Try reseating graphics card and RAM. Remove the CMOS coin battery and connect the Clear CMOS jumper for a few seconds, remove jumper, re-insert coin battery, turn on monitor and power up computer. Did that work?

Hi @bohaoz
Do you have on-board video? You may need to connect the monitor to video outputs on the motherboard first to set-up the BIOS settings. In the settings, there is the ability to set the default video output to PCI GPU Graphics.
Be sure to check all power connections to the motherboard. It is easy to miss some small important connections that will make all the difference. Here is an excellent guide on further troubleshooting if needed.
Best of luck!

Is the monitor on the right setting! lol I’ve done that
Could be these types of hardware
PSU, orThe GPU is shorted not giving drawing enough power to display fans move looks as it is working
I would recommend trying reseating all connections 1st Starting with reseating Ram and make sure you have them placed in the correct slot Worked for me before
If not disconnect the hard drives boot to bios could be a windows drivers are corrupted
last but not least do the whole thing CPU reseat and all the connections full disassembly and reassembly if that doesn’t
USE PSU Tester and if its good it is your GPU failed

@bohaoz let us start with the make and model for your motherboard. Also, let us know if you are using a dedicated video card or how you connect your monitor to the computer.
