PC will NOT Post , NO Display , can’t boot up , HELP!

[Bogut]

Hi guys, i built a pc from scratch but i am having trouble with the pc, its booting up fine ( fans/rgb are all turned on/spinning) but will not display anything on the monitor, need to access bios in order to install windows via usb. But i couldnt get anything on the screen despite everything has gotten power.

Ive had this problem before with another pc, all i had to do was reseat the ram/test it out using only one ram stick into different slots one at a time. Ive tried this method and it isnt working in any slots, i dont think the ram is not seated properly as i had to push it down untill both side clicks in.

CPU 8pin is connected, 24pin also connected. Ive tried plugging hdmi into motherboard and also gpu but still no luck. I also have motherboard speaker plugged onto the mobo but it isnt making any beeps. As you can see HDMI does detect device is connected when i turn the pc on. Any help would he appreciated! Thanks !

Build

Anybodyy? Im out of ideas,
-unplug power cable, took the battery out for 10mins, hold power button for 5seconds, put in battery n powered on , no luck
- took out motherboard and everything out of the case, tested it outside of the case still no luck

You say it is not displaying anything on the monitor, but then show a screen shot of the inputs - apparently being displayed on the monitor. ???

I would try a different video cable.

With a card inserted, that's is where you connect the monitor to. Since that CPU does not support integrated graphics, the motherboard's graphics' ports will have no output.

Are you sure the monitor works fine otherwise? Have you tried it on another computer? Have you tried another monitor on this computer?

Are you 100% sure you only inserted a standoff in the case where there is a corresponding motherboard mounting hole? Oops - never mind. You said it does not work outside the case either.

I would try a different PSU. If still no luck, you need to try a different graphics card or try that card with a different motherboard so you can determine if your motherboard, or the graphics card is bad.

You don't want to attempt anything that might void out your warranty or return policy.

I would first try a different PSU

is that a sony bravia tv you have connected?..please use a proper monitor and connect the tv as a secondary display...

To show you that it does detect input of hdmi, refer to HDMI 1 ,
HDMI is connected on gpu, not the motherboard.
My monitor/tv works fine with my other pc.

Is it a bad thing to use my tv as a pc monitor? Been using it eversince without issues lol

 

[Mr Bill]

If you take your tv remote and scroll down to HDMI 2 hit enter what happens?

Did you check RAM on the motherboard's QVL list? You didn't list the manufacturer and model.

Not at all. Most TVs made for the last 5 - 10+ years have supported computer input. After all, what is a TV but a monitor with a built in tuner.

It will go to my other pc, as im using hdmi 2 on that. But the pc wasnt turned on , thats why theres no icon on the right hand side indicating there is an active device running/turned on/in use

HDMI 1 is the channel where the current pc with issue is connected

No idea why hes making a big deal out of it lol

He's not making a big deal out of it. Trying a different display device is a sound troubleshooting step.

Try gpu from the other pc ? Examin pcie slot for any visible debris ,hair and what not ,if psu is modular recheck plugs on both ends.

Its a SiliconPower Xpower Turbine ddr4 ram

Already tried another gpu, msi 1050 ti and still didnt work , hmm

Was in a similar situation like you for a recent build, lost more hair on my balding head troubleshooting the crappy mobo, went to MC, picked up another mobo, problem solved, finished the build.

 

[bobbybluz]

Considering what you've eliminated it comes down to a defective PSU, CPU, RAM or motherboard. With ATX fans will spin up without a CPU in the motherboard. No beep codes would mean most likely the CPU or motherboard. BTW big screen TV's work great as monitors, I've been using them for several years.

 

[Bill_Bright]

Depends on the BIOS/Chipset because some beep codes will indicate a faulty or missing CPU. So I'm leaning towards the PSU or motherboard.

The PSU must output 3 voltages. +12VDC, +5VDC and +3.3VDC. 12V fans, for example, can still spin up if the 12V is present but the system will not boot if the 5V is missing or way out of tolerance.

That mobo is new enough to still be able to RMA it as well as the PSU. The odds of it being the CPU are so small I wouldn't consider it if the PSU and mobo are known good unless OP managed to bend a pin or pins. Doing a proper diagnosis online is next to impossible unless we have the unit in hand, it's all educated guesses. Since nothing I now have in my inventory except RAM, PSU's and GPU's is newer than early 2016 I can't speak with experience about new mobos but Asus and ASRock boards won't give a beep code if the CPU is missing. That's one of the reasons I like LED displays on the mobo for codes.

Back in the socket A days I trolled a local Best Buy during a "free PC diagnosis" the Geek Squad offered. I pulled the CPU from a fully functional PC, reattached the heatsink then took it in to see if they'd catch the missing CPU. Two days later I got a call it was ready for pickup. A stern faced kid told me the motherboard, hard drive and RAM were defective then gave me a price quote for "repairs" It was twice what it'd cost me to build the PC. He then switched to a hard-sell for one of their prebuilts with an alleged deep discount. I kept a straight face, got my PC and left. When I got home I put the CPU back in and it's still working today as my vintage museum piece I fire up around once a year. Asus A7N8X with a Barton XP 3200+.

Its a Silicon Power Xpower Turbine ddr4 ram

It might not be on the QVL but it's cheap and it works, as I have used it in a build with a 3600 previously on a B450.
Edit: with no Ram inserted it should give a beep code.
Does the Motherboard have LED's to indicate the boot stage and possible faults?

Did you fire up your board with out any RAM stick? Board will definitely beep/complain if the board is still alive.

When you turn on your PC, does the Num+Scroll Lock lights blink momentarily and go away?

Like others suggested try another PSU.

Ive tried without any ram, but still no beep from the speaker.
my keyboard rgb is lit when i turn it on

the only method i have not tried is doing a bios update. As bios update are kind of risky, especially if i cannot get display , how do i do a bios update? Ive read that u can use qflash plus by just pushing the button on the board. Anybody tried this before?

Unfortunately it doesnt beep even without any ram stick installed which is odd. Do u think i should do a bios update? Someone has mention that he still needs to update a b550 board in order to get it posted upon booting

No, don't update the Bios, it supports the 3600 out of the box.

How do u tell the mobo is the issue here? Because everything thats connected to the mobo is receiving power, which means the mobo is working right? Same for the psu, its powering up just fine, my tv does detect an input of the hdmi when i turn on my pc, just not posting n not giving any display

Mobo can still light up and be toast at the same time.
I'd suggest try a new HDMI cable

The HDMi is working just fine, its was connected to the ps4 and been working without issues, tho i did try using the other hdmi which is on my other pc, same thing, it detects input, jist that the pc is not posting

 

[Vayra86]

Is the motherboard speaker even connected? No beeping unless you have one

No POST means you need to have those beep codes or you're dead in the water and RMA is the only other solution

 

[Bogut]

‘Have you updated the BIOS on your motherboard, some B550 motherboards (Mine included) wont post without a bios update to support zen 3’

This was taken from LTT forum, maybe the board bios does need an update?

Is the motherboard speaker even connected? No beeping unless you have one

No POST means you need to have those beep codes or you're dead in the water and RMA is the only other solution

Ofcourse it is connected! A 4pin tiny round speaker
