PC WILL NOT POST TO DISPLAY

[jlcald839]

Hello, I have recently built a $900 Gaming pc. I turn it on and every fan, all the lights it all turns on like a normal pc would do. But it then doesn’t post a signal to the monitor. I leave the pc on and still no signal even after 20mins. I have tried every troubleshooting step, What I have done : take out GPU to destermine if it is a driver issue. Reset bios. Re seat cpu. Unplug everything from psu and plugged it back in. Nothing is working.

computers don't have drivers loaded until the os loads so you have a hardware issue not software

 

without knowing what the machine is it'll be hard to help

After further investigation and research it may be HDD problem. HDD and ssd are on because I can hear HDD noise and ssd is warm. So there’s power going to them. It may be my SATA cables or te system is trying to boot on the HDD or ssd but it can’t. I tested this because if you plug in a keyboard and press caps lock if a indicator saying you have it engaged doesn’t come up there isn’t a boot sequence or HDD recognised so it won’t boot

Do you get any beeps ? 

Or a error code on display ?

 

dit you connected every cable including power supply to the 4-8 pins at the gpu?

dit you put the motherboard holders under the motherboard ?

do you have onboard video ?

is onboard taking priority ?

is ram inserted right

so you fill equal slots ( brown and brown. White and white )

so many more things that can do this

so please provide us some more Info

 

Do you see a post screen to enter bios ? If not then it isn’t even your hd as it doesn’t even get there

Nothing will go to display it is just blank screen. Everything you listed I have checked. Ram is in b1 and b2 on my board which is what the manual said to do.

Ok 

do the following

 

unplug everything

only plug-in 1 ram slot

and your video card if you do not have onboard video 

And of course your cpu and a cpu cooler

 

then test again

on the mobo you should see the post error codes or your screen should turn on

 

is it a brand new mobo ?

it could be broken if it does nothing

but the video card could also be broken

or even the cpu

 

so it need to provide a error code else it is really hard to debug and most likely is it then the video card

I guess your $900 PC must have a debug led if not a full post code display. If so, check it carefully what it outputs in the post process. Typically, there are 4 arrays of LEDs and they should stand for CPU, RAM, VGA, UEFI mode-in respectably. And do your action accordingly. Try out different dram combination, try resetting the CMOS, flashing updated BIOS. 

 

Or don't insert your drives at all, maybe for some weird reasons, I've seen faulty drives not even letting it into the UEFI, if not directly into the OS.

I hope i am not breaking any rules by linking to toms hardware.

20 steps one should go through. every time i have posted before in regards to something like this, i am linked to this.

 

try 1 stick of ram in the b2 slot. you could have a defective cpu with odd lane support, or a bad stick of ram.

 

but i will say that there is usually just one little thing that is preventing a post.
