[SOLVED] Why isn't my monitor receiving input?

[cadok5]

I have built a new computer with all completely new parts. When i start up the PC it seems to all be working well on the inside, fans running and LED lights on. However, when I try to get it to connect to my monitor it says "NO SIGNAL".
I have tried many "fixes" for this. First, the cables and monitors are fine because they were used on my last PC and worked perfectly. Secondly I have attempted to use both a Display Port cable and an HDMI cable. On top of that I have attempted to plug both of these cords in both my CPU and GPU. I have also attempted to boot with one stick of RAM. I have booted with my SSD removed. I have removed my GPU and firmly replaced it into its slot. I have moved the GPU into a second available slot.
None of these have helped.
I have a RTX 2080 ti and an Asus Prime Z390-A. Please help.

I believe I have it wired correctly now, but the fans do not turn on still.

How have you got it connected now and did you connect the large sata power cable to the psu?

The sata cable is connected to the PSU.
The 2 fans are connected into the 4piece splitter.
The 3 pin cable is plugged into the cpu_fan on the motherboard.
The Mini USB cable crosses the motherboard and plugs into one of it's USB 2.0 slots.

That looks right to me but why the fans aren't spinning im not sure, setup may still be wrong. Wait if you can for verification from someone with more knowledge.

Okay, I'll probably be off to bed then. I need to be up in 7hrs from now. Thanks for all the help so far!

 

[boju]

You're welcome. Hopefully get this sorted soon. Gnight.

The cooler is totally good, it's exactly how it should be. Dunno why @boju would need me lol, ya'll are doin great so far.

What I'm not seeing is some leds lighted on the mobo, there's 4 of them right above the main power connection. This generally means the cpu isn't getting power, so you aren't actually going into boot process, so you won't get any signal.

What I'd like you to check is the connections. The main power can be a pain to seat fully, especially on a new motherboard, but it'll handle a good push.

The other power is the EPS in the very top left corner. Make sure that's actually the EPS/CPU/ATX12v 4+4 connectors and not the 6+2 PCIE, and see if it's seated fully. Might have to pick the board up and get a good grip on it.

Also make sure the modular connections at the psu are good.

I'd move the ram stick to slot #2, it's currently in slot #4.

Thanks man, i appreciate it. Seen you have experience with water cooler installations and thought maybe you could check the wires are where they should be and not preventing motherboard from operating cpu.

I have no experience with this and was getting confused with the instructions 😊

First of all, make sure your display cables and power cables are not loose and or not faulty. If that doesn't make sense to you or they are working fine from other computers well I assume that's not the case.

But, sadly I have another issue for you. I am suspecting a GPU or PSU problem right here. Are your fans and leds working properly or they are misbehaving?

A faulty GPU can cause this issue obviously, what you can do is try your GPU to another computer. If the PC runs fine using the graphic card then it's not faulty.

Being said a GPU can cause this issue, a faulty PSU can cause a misbehaving GPU. Why? Well because a GPU is a power hungry hardware. It is the first hardware that shows signs and symptoms of an unstable power or faulty power supply. Everything else will lead to a monitor no signal issue.

If this isn't the issue, please check your motherboard and processor.

NOTE: I assume that you did all the basic trouble shooting technique first. If you did not, then go back to zero and start with the RAM and CMOS Battery.

Have you tried booting without the GPU? or maybe using the built in graphics? It's the display, so make sure the GPU is not faulty. You can also try it to a different computer to make sure.

New doesn't mean working.

Did what you said and stuff came on! Fans are running and I heard the water running through the cooler. Still not getting any input to the monitor though. Of those 4 lights above the main power you mentioned, only the DRAM happens to be lit.

I have tried and still am at the moment trying to boot without the graphics card and instead with the integrated graphics. Problem is that isn't working either. Will try the GPU in a different computer when I get the chance though!

Lights and fans are working. Even when I have the GPU in all the fans seem to be working well. I believe some lights are not coming on that need to be (BOOT, VGA, CPU) that are above the 24 pin connecter.

 

[cadok5]

When I press the power switch the light above the 24pin connecter on the mobo labeled "CPU" flashes red for a moment before turning off, then an orange light comes on next to "DRAM".

 

[Karadjgne]

Those are diagnostic leds. They should only come on for a second or so. The dram led being lit means a ram error of some sort. That can happen in several ways. First I'd try reseating the ram several times, inside the slot is little spring loaded arms and they'll slightly scratch your ram, on the little gold keys. This is done so that it's a direct, good connection. If the arms fail to scratch the ram due to oxidation or finger oils etc then it'll throw an error. Reseating a few times, making sure the ram is locked down solidly can fix this.

If that fails, clear your cmos. There's directions in the manual, but once locating the 2 pins, unplug the pc, hold the power switch for 20 seconds then just use a paperclip or flat head screwdriver and short them together for 10 seconds. That forces the bios to do a hard search and reload every components info and drivers etc. Which includes going in search of the ram.

Make sure however you have the monitor plugged in, the monitor Input matches, there'll be several modes, like vga, dvi, hdmi or dp etc. Otherwise if you have hdmi chosen on the monitor, hooked up through a display port cable, you'll get no signal.

 

[boju]

Do you still get a lit dram led if ram was in the 4th slot? Noticed it's been moved to the 2nd comparing to your other pictures. Asus changed their memory channels and first A2 slot for single memory is the outer dimm.

 

[Karadjgne]

They did what?

 

[boju]

Not sure if all 300 series Asus boards are configured that way, id have to check but for z370 and 90, yeah, they've changed it. Afaik, rest of the 3rd party vendors still configure the usual way.

 

[Karadjgne]

Ok, that's the dumbest thing I've seen yet from Asus, would mean a total reconfiguration of i/o for the primary and secondary gates to match up with the cpu. It's also confusing as now DIMMs read 4-2-3-1 instead of the normal 3-1-4-2. Gigabyte had a similar system years ago, and scrapped it in favor of a standard approach.

@cadok5 , I guess if @boju is right, which from my viewpoint he is, put the ram back in the 4th slot like you originally had it, my bad for saying to move it, I didn't know Asus had pulled a fast one and changed ram orientation.

 

[boju]

Was only recently i found out. The OP i was helping told me the last dimm was used for single stick because id assumed 2nd slot. Couldn't believe it and checked manuals. Z270 is still the traditional way though so dunno why they changed it for the 300 series. Maybe they thought this way is more convenient for large coolers. But even then, don't think it's that much of an issue, the D14 cooler im using leaves plenty of room for the 2nd slot. Dunno.

 

[Karadjgne]

Yeah, it's a bone head decision. 99% of ppl using Z390 mobo will not only be using the most powerful cpus they can on it, but also that'll require the largest coolers. Ok, I could see that logic if it wasn't for the fact they'll also be using dual channel ram, which puts the second stick in slot #2, exactly the same setup as standard A2/B2, only they have it labeled as B2/A2 now. Nobody pushing a i9 9900k is using a single 16Gb stick.
