Hey! 

Okay. So I've researched for the past few days and figured all my mistakes (using HDMI). I just built this PC (specs below) and I tried everything to show something on the screen. All I get is a "No Signal" error. I've tried moving the RAM (only have 1 stick) and I've checked that nothing is damaged. When I connect the PC and turn it on, all the motherboard and fan lights turn on. 

Also, I'm using VGA (before, I was using HDMI) and it doesn't connect to my video card (only supports HDMI and DVI). I've tried everything to fix this from removing the video card and trying but nothing works. 

It's a brand new PC so I don't think I need to dust it or there's any dust issues. It looks completely dust-free. 

Another thing is that I haven't connected some cables from my power supply to my motherboard or any components (like extra drive cables). Is that something I should worry about? 

Here are my specs: 
Asus Prime B350 Plus MotherBoard 
AMD Ryzen 5 1600X 
Wraith Spire Max Cooler 
Zotac GTX 1050Ti 
1x 16GB Ballistix DDR4 RAM 
Corsair VS550 Power Supply 
Barracuda 2TB SATA 
Kingston 120GB SSD

 

(Basically, my question is why is this taking place? Yes, I know my GPU doesn't support VGA so I removed it and tried connecting the cable to my motherboard with no success.)

first try cleaning the the ram slots with a soft brush and also use air duster can and blow a little

then take out the ram stick and blow off any loose dust using canned air (hold the module by its edges)

then clean the contacts of the ram using a cotton swab slightly moistened with rubbing alcohol. you can also use a soft cloth that does not leave fibers behind, such as a length cleaning cloth.. let the ram dry then try.

 

if that doesn't work try removing the battery, then clear cmos, let the battery out for 10 minutes, then put it back..

Nope. Didn't work. I even tried connecting it to a different monitor but same story - No Signal.

do you hear the sound of windows starting up?.. if not, are you sure you are connecting your HDD with the two cabels? one coming from mobo to HDD, and the other coming from psu to HDD.. remove your ssd for now, try work with less components installed as possible.

 

also if its a brand new build (you never use it before), you would need try checking if ths cpu fan is seated properly.

try to unplug all cables from mobo, hdd and plug it again, make sure it is plugged.

  

i would suspect the psu, but corsair known to be good. i wouldn't rule out anything though and i would try another psu, or test mine on another pc.  

 

or maybe in the end it will turn out to be small issue like your vga cables.. try another one.

I don't even have windows yet xD, but I've got it on a USB Flash Drive. Thanks again dude, I'll try it all out. :)

 

Edit 1: The HDD is connected all well and fine. I've removed the SSD from the drive cage and disconnected it for now. Still now working.

 

Edit 2: I don't have another PSU and I've tested this VGA cable with other devices. It works a charm.

have you applied thermal on cpu in a corrected way (a shape of a small dot on the middle of the cpu) so thermal can spread and cover all of the cpu. also you should check if the cpu fan is seated properly. 

 

start with the simple things, like trying a different monitor, maybe yours is set on a kind of resoultion that isn't working with your new build somehow and giving you no signal. also if you could try using another hdd that have windows installed. 

 

if all of that didn't work you should try to borrow a psu, or test yours on a different build.

 Take out the RAM out of the motherboard and turn it on,  It will scream at you this is normal. If not check the CPU assembly. Make sure you have it set correctly with lining the PIN 1 and add thermal compound and reseat the fan assembly.

You say "haven't connected some cables from my power supply to my motherboard".  Are there any power connectors on the motherboard left unconnected?  You need both the 24 pin ATX connector and the 8 pin EPS connector (which powers the CPU) connected.

 

The motherboards VGA connector will not do anything with a Ryzen CPU installed.  It is only for use with AM4 CPU's with integrated graphics.  You must connect the monitor to a discrete video card.

Thanks everyone for the help.

 

Does the quote above mean that I need a DVI cable to connect the Video Card to the monitor? 
I've got all the important cables like the 8 pin EPS connector and the 24 pin ATX connector connected. I just didn't have extra drive wires and a PCIe connector in because my Video Card doesn't need one.

 

Thanks, again, to everyone. I'll try get a DVI cable and work this out :).

The motherboard onboard graphics with your particular CPU needs a standalone graphics card to display correctly. The VGA on the motherboard only works if you have an onboard graphics processor. 

 

Discrete is another word for a standalone graphics card (which is 1050ti). In my opinion, it is better than an onboard graphics card because onboard uses system resources like RAM and the CPU. While the card has its GPU and decided ram on the card  Connect your DVI cable from 1050ti to the monitor.

 

Depending on the style of your PSU you may have extra cables for future upgrade or a modular PSU only connect the cables you need (is only for cable management and to look nice for people when they open it up for maintenance) 

 

Make sure you have the important ones connected securely like ATX-24, 8 pin EPS, SATA Power and data

 

Hope that helps :)

Yep if the video card does not support VGA (I believe analogue outputs have been discontinued on Nvidia 10 series GPU's, so a passive DVI-VGA adaptor will not work) then you will need to use a monitor which has DVI or HDMI.

Thanks you guys. I'll get my DVI cable by today and try it out.

 

Plus, if I try to boot without RAM should I get a beeping? That's what someone else informed to me but I don't seem to get any beeping.

Only if you have a speaker connected to the motherboard header.  Many cases these days don't have one.

Usually, when you buy new cases  they have this in the box

10Pcs-Motherboard-Speaker-Alarm-Mainboar

 

 

When you don't RAM installed  It just beeps Were just determining if the CPU and the fan assembly is initializing upon POST and the EPS 4 or 8 pin has power and 24 pin has power. then we usually check the items connected on the motherboard. Although try your DVI cable first
