H'i Folks,
Please bear with me as this is my first post, and I'm not sure of all the rules yet. Thanks.
Anyway, I've just built a new desktop computer and everything seemed to be going alright until I powered it up for the first time. My problem is my monitor just says "no signal" I think I've connected everything up alright from the PSU but I'm not absolutely sure, this my first attempt so it's all pretty new to me. I keep thinking I've missed something. The motherboard is a: Gigabyte GA-A320M-S2H-rev-1, with a CIT 1016 Glos black micro ATX PC computer case mATX with a PSU A 500W power unit.
I don't know what else to do. So I was wondering if anyone could help me with this. It would be greatly appreciated. Many thanks.
STUMPTXXX.


 
Have you got a video cable going from the GPU to the monitor, and set the input on the monitor to the correct port?
 
please fill the spec of your pc first

H'i Kayjay, thanks for your reply. I have my computer connected to my monitor with a VGA slot, and obviously a mains cable. I'm not sure what you mean when you say "a video cable going from the GPU to the monitor". I don't know what they are.
 
Is the cable from the monitor connected to the Motherboard or a graphics card?
What Processor is installed?

H'i Caring, thanks for your interest. The monitor is connected to the back of the computer via a VAG socket which is connected to the motherboard. The Processor is: AM4 Socket: - AMD Ryzen™ processor - AMD 7th Generation A-series/Athlon™ processors
 
Processor - Full name please and since it is AMD also RAM, full name there as well.
 
It's possible the motherboard might need to have it's Bios updated to recognise the 7th Gen Processor as the 3000 series came along later and early version of that Motherboard can't run without the update.
Later versions shipped in a box marked Ryzen 3000 Desktop Ready.

Have you any idea how I can update the Bios if I can't get it up on the monitor?

You can’t with that motherboard. Why don’t you answer our questios? You made the computer so you must know what components you put inside. Since the MB doesn’t have a LED ready-out of the post you don’t have any idea why it doesn't post. If we are to help ......

After watching various videos on youtube, I thought I was competent enough to build a desktop computer myself. After looking at different M/B and other items that were compatible. I bought this M/B as a bundle.. and I thought I only had to connect to PSU, configure the Bios, add an o/s and thought everything would be working ok. I was obviously wrong. I will have to contact Gigabyte and see what they suggest. Thanks for your help anyway.
 
@stumpyxxx can you update your system specs or share the exact models of your components? You've got motherboard covered. You mentioned a 7th gen A-series processor, but which one? The motherboard shouldn't need a BIOS update as the 7th gen Athlons were launched back in 2017. If it's easier, you could probably just share a link to the bundle you purchased...
 
Stumpy, do you have graphic card, I think no?
You have monitor cable connected to motherboard port, right?
My guess is your CPU does not have on-board graphics.
So, as already asked what CPU do you have exactly? Model number please.

About Us
 
Ok, thx, so your CPU has on-board graphics.

You don't have video card, you are using CPU graphics, right?

When you turn computer on what is happening? Are fans spinning, lights turning on? Any beeps? Just nothing on monitor?

Are you sure all power cables are connected correctly. In particular big power connector on the edge of motherboard and small 8 pin next to CPU?

What monitor cable you use? I mean which port on motherboard, VGA (black on top), DVI (white bottom), HDMI (smallest one next to two others).

Are you sure monitor is set to correct input? (I assume you know that monitor itself works)

If nothing is faulty, this looks to be a possible problem. VGA only supports up to 1920x1200 res (I checked the mobo manual). Monitor-cable-connection seems likely. Somewhere along there.

Double check your cable connections, make sure monitor is set to the proper input source. As @Tom.699 mentioned, what's happening inside your system? Are your fans spinning?

Yes, I'm using CPU graphics, and no I don't have a video card.
When I turn on the computer, the on/off button lights up, all fans are spinning, there are no beeps, and the only thing on the monitor is the message "no signal" All cables connected correctly including the main large motherboard connections and the small 8 pins one too. The monitor connection I'm using is the VGA. I know the monitor is working fine as it is normally used for my wife's desktop computer, I've just borrowed it. I'm not sure what you mean when you say "is the monitor set to the correct input". How do I do that?
There is one other thing that might have some bearing on this issue is when I try to turn it off with the on/off switch, it doesn't turn off, I have to turn it off at the plug socket. I put that down to is that you normally switch off by shutting down with the computer software.

Checked and double-checked cables, all good. they all work on my wife's desktop computer.

We're not saying the cables are faulty, just incorrect for your use on that system.
What works on hers may not work on the new system.
Post pics of connections and cables if you can.
 
I'm not sure what you mean when you say "is the monitor set to the correct input". How do I do that?

I mean if monitor has multiple inputs you may need to manually select which one is currently used using monitor menu/buttons.

Can you try it with other port, HDMI for example? You can connect it to your TV for test.

If it's a regular bog-standard monitor, it'll have either touch captive buttons or physical buttons to activate the on-screen display. The on/off switch should also be one of those buttons, afaik there's never been any monitor that needs to be shut off in software. They all have on/off buttons. You need to find the buttons to activate the OSD and change the input setting to match the port you're using. Again, pictures would be helpful, along with the model name of the monitor.
 
It would be handy to know exactly the make and model number of the monitor because the mobo has VGA, DVI and HDMI outputs.

H'i Caring1, I've tried the monitor connected to a neighbours computer as well and it's fine, I've also connected my new computer to his monitor, and it comes up with the same message "No signal"
 
@stumpyxxx

Can you provide a picture please of the PC mobo (your actual build) with power running?

For example:

Can you try using an HDMI cable:

And can you tell us what monitor you are using, and check it has HDMI inputs?

Using the HDMI cables will help us determine if there's any weird connectivity issue between your build and the monitor. My PC had a 'no signal' and it was down to not choosing the DP (displayport) input on the monitor (manual buttons).


Thanks.
