No display on monitor (gpu fan spinning and 8 pin plugged in)

jcspec · Oct 22, 2016

So I currently have an ASUS GTX 1070 turbo. I finished by build 1 week ago and it worked fine. I was playing games and such so everything was working. Today my screen froze and didn't get any response from task manager or anything so I held the power button to turn it off. Now whenever I turn it on, it says no signal on my monitor. I tried plugging in my old gpu (amd hd 7950) and I didnt get a signal from that. I took my gpu out and tried hdmi and dvi cables on the motherboard. No signal there either. I have integrated graphics from my i5-6600k. I tried unplugging the little battery and waiting a minute too, didnt work.

Monitor and cable are fine because I connected it to my xbox and got a signal. I checked the psu connection. The gtx 1070 has a red led when it doesn't have power and a white one when it does. It has power. The computer is booting because all fans turn on and my mobo led is on.

Any ideas on what's wrong?

Do you a have any kind of beep code when you turn on your PC? A single short beep should be heard when everything is ok.
Anyway you could also test your Ram modules one by one to make shure they are not the problem.

my motherboard did not come with a speaker. I tried plugging in a speaker from my old comp in. It doesnt beep at all even when my pc did work.

Usually the case brings a small pc speaker.. not the Mb.
Did you test your RAM sticks one by one?

Yes. I tried swapping them and 1 at a time. No signal

Does it look like your computer is starting normally although you have no signal on your monitor? Does the HDD Led on you case blinks like in a normal startup?
Do the Fans in your case/CPU/GPU start to rotate?

CPU fans turn on, GPU fan turns on. HDD led does not blink at all, I just noticed that. The PC turns on like it normally does. leds are on and all fans are spinning.

If the HDD led doesn´t blink, that means your computer is not loading anything from your drive. So it´s not correctly starting. It´s not POSTing for that matter. (POST = Power On Self Test) I am assuming your HDD led is correctly connected to your MB and was working before. If you have a HDD for your SO, even if your HDD led isn´t connected you should clearly hear it reading stuff from it when it´s starting.
So that means that there is a faulty essential component that is not allowing your PC to POST correctly.
If you tested everything else, my bet is that your Mb died on ya..
But try to test everything again individually. Preferably on another computer if you have the chance. GPU, RAM, PSU..
Try also disconnecting all the power cables from your MB and reconnecting them.

Ok I thought it was either my motherboard or my cpu. But my motherboard light next to the front panel connections is lit up.

It can be either the MB or the CPU.. But lights on the Mb lighting up don´t mean it´s fully functional. Still, my bet goes to a faulty Mb.
But try to test everything else if you have the chance.
