When I use dvi my computer screen goes black but I get no post

But I still get no post screen

It boots up for a sec then shuts down and boots up and stays running

REMINDER: this thread is not to ask questions about your PC. Please create a NEW thread if you still have issues after going through this thread.

 

So, you've put together your brand new, shining rig. You plug in the power cord and push the button. Nothing happens. What now? The answer depends on what is happening:

 

 

The machine doesn't do anything. No beeps, LEDs or spinning fans.

1. Check if your power cable is firmly plugged in on both ends (you would be surprised how many issues this resolves)
2. Check if the power supply (PSU) has a button to cut the power to the machine. Check if this button is in the position denoted with ON or I
3. Check if EVERY power cable is plugged in securely, reseat if necessary.
4. Check if the power button is installed correctly (consult your motherboard manual)
5. Try shorting out the pins you connect the power button to manually. If this powers on your system, you have a faulty power button.
6. Check with a device of which you know that it works if the power outlet you're using is actually providing power.

If this hasn't solved the problem, check if your PSU isn't dead. To do this, you can follow these steps:

1. Unplug your power cord and/or flip the switch on the back of the PSU in the position denoted with OFF or 0
2. Unplug every connector coming from your PSU (this is very important)
3. Using a bent paperclip, short out the green wire on the 24 pin header with any of the black wires, like so.
4. If you have a PSU that shuts down its fan under low load, or a PSU that is fanless, connect something small like a hard drive to it.
5. Plug in your power cord and/or flip the switch on the back of the PSU in the position denoted with ON or I

If the PSU does NOT power on (the fan/hard drive you connected should start spinning) after following these steps, your PSU is in all likelyhood defective. Request an RMA.

If the PSU DOES power on, then the problem is most likely your motherboard.

 

 

The machine does power up, but my screen remains black (no POST).

1. Make sure your BIOS version is compatible with the CPU generation you're trying to run in your motherboard, you can consult the manual or the manufacturer's website about this.
2. Check if EVERY power cable is connected. Auxiliary power connectors included.
3. Make sure the cable coming from your monitor is attached securely to the graphics card. Also make sure it is securely attached to the monitor itself.
4. Make sure your PSU is powerful enough to power your complete system.
5. Make sure your monitor works by testing it on a different computer.
6. If you have both a dedicated GPU and an iGPU, try your monitor on both the outputs on the graphics cards as well as on the motherboard.
7. Make sure all connectors and cables are plugged in securely, reseat if necessary.
8. Make sure your RAM, CPU and GPU are plugged in securely, reseat if necessary.
9. If the motherboard you're using has debug LEDs, check the error code and consult the motherboard manual to see what it means.
10. If you have a debug speaker connected to the motherboard, note the beep sequence and consult the motherboard manual or this thread to see what it means.
11. Try clearing your CMOS.
12. Try booting your computer with only a motherboard, CPU and one stick of RAM attached (if you don't have an iGPU, plug in your GPU as well ).
13. Make sure your GPU works (if you have a dedicated one), try it in another computer.
14. Make sure your RAM works, try it another computer.
15. Make sure the RAM is compatible with your CPU and your motherboard.

 

If the PC still doesn't POST after this, create a new thread and, as explained here, post IN FULL DETAIL about your problem. Make sure you include the following:

1. System configuration
2. Troubleshooting steps you already did
3. Any additional information that may be relevant.

 

Lastly, if you find any mistakes/grammatical errors, inaccuracies or missing steps in this post, please do post them in a comment so I can fix it.

 

 

PS: @TheXDS has posted how you can do some more in depth checking of the internal circuitry of you PSU. The only thing you need is a multimeter or potentiometer (if you're oldschool :D). You can find his post at http://linustechtips.com/main/topic/42440-readme-how-to-respond-to-a-no-post-or-no-power-up-situation/?p=4561958

ASRock H110M‑ITX LGA 1151 Intel H110

i5 7600k

radeon graphics card 

750 corsair modular power supply 

Anarchy ram 

all of those should work right 

But it still won't post

Ok new update it boots shuts down for a sec and boots on and stays on

What's sorting?

Are you saying shorting?

So what do you think it may be 

ASRock H110M‑ITX LGA 1151 Intel H110

i5 7600k

radeon graphics card 

750 corsair modular power supply 

Anarchy ram 

all of those should work right

That sounds more like something sorting or RAM issue. If you can't get into BIOS, I don't really think its cooling issue. Even loose contact with cooler should let you into BIOS and check the temps.

That's why I think it's a the overheated protection 

I don't even get a picture or anything but I hear a pewww when it shuts down instantly 

Not yet I gave up tonight 

If so that's what I'm hoping tbh bc I have a new cooler coming in

I'm building a itx I have everything hooked up io is backward but other then that when I boot up for the first time it runs for 15 seconds shuts down then boots back up 15 seconds later pretty sure it's not my psu bc everything is getting power

I run a Cryo rig and it handles my atx when I push it I like no tuna but idk

Yes it would work. But you would be better off getting something like a Cryorig C7 and if you need something really slim then the C1. What case are you using?

So all intel stock coolers work?

And I have a full atx 750 power supply that hovers over it

Cooler master elite 130

It's for a mini itx

I'm making a min itx build and was wondering my i5 7600k didn't have a fan could any intel stock fan work for it I'm having issues finding one that lga 1151 compatible in the specs when I'm looking?

Know any good extra ports that I can put on

What can I put in this port

Well that depends on a number of factors. Depends which game you're running, if you have Vsync on/off, what graphics settings and resolution etc. At times, the GPU will be the bottleneck  (which is what you want), or the CPU will be the bottleneck (which you don't want). 

 

You wan the GPU at 100% or close to it while the CPU is at 80-90% or less (on all cores). Your PSU is probably not the bottleneck. You'd know because it would just shut off to save itself.

my gpu runs at 99 bc i have it toned down to 70 c for heat so my motherboard doesnt heat up and most games only run 4 cores at 100% leaving the other 4 cores at 1% the only game i really have that runs all cores is the division and that still only puts 4 cores at 75 and the other 4 at varous numbers
