So I've already googled this multiple times and have asked a lot of people and nothing seems to work for me. I turn on my PC and the fans run, lights turn on, everything is good, but the monitor shows no signal and then goes to sleep. I've tried every single possible ram combination, that doesn't work. I'm using a DisplayPort cable from my monitor to my gpu. I also tried with an HDMI to my motherboard to try the onboard graphics but that doesn't work either. I don't think the gpu is fried as everything is brand new. I also tried installing the speaker cable to see if I can hear beeps but i can't hear any, maybe I didn't put it in right? I also came across another forum where apparently removing the power cord and holding the on button for 30 seconds to a minute worked for a lot of people. But the power cord from my psu to the wall? Or the monitor power cord, and I hold the on button that's on my PC case? Any help would be appreciated

Hi

Have you tried another monitor ?

Have you tried another graphic card ?

Yes I've tried my friends monitor, does not work.

I've tried onboard graphics and my graphics card, both not working

Usually when I get a no display signal, 99% of the time, it's a cabling issue HDMI or DVI, otherwise, I try to reseat the graphic card after a carefull clean-up

Sorry, I am stumped.

Yeah it's not a gpu issue, but why would the gpu not work though? Can the motherboard cause the gpu to not work or could the gpu be fried? How can it be a cabling issue, like what do you mean by that? I only have 1 cable going from the monitor to the PC and that's the HDMI. Do you think it can be a CPU or mobo problem?

You must troubleshoot the situation. Can you try another graphics card ? If it works, then you will know where the issue resides.

Just out of curiosity, what is your GPU's make and model ? Is it brand new or brand old ?

No I don't have another graphics card but I tried onboard graphics and those don't work. GPU is GTX 1070 and it's brand new

Buzzzzzzzzzzz !

Is your GTX 1070 with your mummy board?

If your onboard card and GPU don't give you a signal, if no other monitor will work, If you didn't need to install drivers for the GPU I would look into the mobo problem. Kind of logic isn't it ? Kind of a turn off also.

Yes the 1070 is on the mobo,

I can't really install drivers when I haven't even been able to turn on my PC yet. I really do hope it's a motherboard problem, I'm getting it replaced in the next couple of days, have any good z170 motherboard suggestions? Preferably under 140$

If it's for gaming, perhaps:

ASRock Fatal1ty Z170 Gaming K4 or

Gigabyte Z170X-Ultra Gaming

This it out of the blue for the money you wish to spend. I think the above are available on Amazon. While you are on Amazon, you can also do your grocery shopping and get it delivered by drone.

Good luck
