Question New PC build won’t turn on

[DylBKR]

Hi All,

I have today just built my first PC, that being said it doesn’t turn on at all. Everything is plugged in to the best of my knowledge but my knowledge is very very limited as to where certain wires go, piecing the parts together was fine but when I start seeing wires such as Power SW appear and no manuals giving guidance it’s stumped me. As of current when I turn on my power supply one of the run fans on the case lights for less than a second and turns off.

Any help will be massively appreciated. Here is the part list in case anyone has a build similar to this.

Thank you, I ended up finding this for the b650 but I’m still not able to get power. I’m in the process of unplugging any cables and resocketing any further suggestions will be appreciated.

The CPU power to the top left of motherboard.

Have this plugged in will send through pictures of the build to the thread hopefully allowing you guys to troubleshoot better.

 

[Dark Lord of Tech]

Double check the main power and the CPU power , make sure they are fully inserted , all your hardware is compatible.

Didn’t realise I couldn’t simply upload media. As said though I have unplugged and replugged and I just can’t get anything to come through.

This contains multiple angles of the front aswell as what’s going on at the back. If you require anything else I’m free and active thanks for helping.

Have you gone thru the setup and plugged in all the needed connections , for the board and GPU.

Just gone through and cable managed better, have all 3 PCIEs required in the gpu and sorted out my front ports, unsure if my board has all required connections. I have left over satas and psu sata adapters aswell as molex connectors. My 24 pin is in the board aswell as the Cable labled CPU and yet nothing.

PSU in the powered on position?

PSU in the powered on position?

Yep.

 

[DylBKR]

It’s my bios I believe, when pressing the Qflash back button on my pc I get rgb response.

 

[Dark Lord of Tech]

BIOS should be fine it only has that one available.

I attempted to update it with the latest motherboard bios and as said this provides power to everything but for some reason outside of the update no luck.

One of the more common errors made by a new builder is not installing and/or adjusting the stand-offs between the mobo and the case's rear mounting panel. If you are not familiar with this, check my post of Aug 21/22 in this thread

Question - Previously working PC switched to new case, won't start up

Brief background: Had a case from an old PC build that I reused to build a new system last year. The power button on the old case had given me problems with the old system and would sometimes take multiple pushes to start up. The new build was built in this case and everything worked fine...

Another major diagnostic technique is called "breadboarding", and you can use that. It is a process of testing your components outside the case on a dry non-conductive surface. You start from a very basic set of parts that should partially work if everything is OK, then slowly add other components one at a time to try to identify a faulty one. Read my post of Aug 23/23 in that same thread for more info.

You might try combining these two things in this manner. To inspect the stand-off locations and possibly correct them, you have to remove the entire mobo from the case. Once you have done that you MIGHT consider placing it on a safe surface still with all of its components installed and trying to power it up that way. IF it all works perfectly with every component installed you do not need to go through the step-by-step process to find any faulty parts. BUT the fact it works "outside the box", but not when installed in your case, would focus you on stand-offs and any other possible sources of short circuit contacts.

Thank you for replying even after this thread has been up for a while I finally found the issue. I believed at the time I’d been sold a faulty motherboard so I began taking everything apart when everything was out except the MoBo and PSU I said screw it and attempted to update the bios using Q Flash Plus one last time and what do you know it worked and I began to get power to my machine I put everything back in and now have a PC that boots to the AMD bios. That being said I do need some help with the windows installer. I have downloaded it onto a USB and yet when I plug it in and make it the first in the boot order it doesn’t boot into the installer just back to the BIOS. Any suggestions?

You need to PROPERLY connect power to the GPU!!

Never mind. I see that's already been covered.

LMAO, don’t know if you saw but I ended up having to strip my machine back to just the psu and motherboard and using G Flash Plus to update to the latest BIOS so certain components worked, I now have functioning PC however do need help with windows installer, my pc isn’t recognising it on the USB it’s the first thing in the boot order and yet doesn’t boot it only goes back to the BIOS.

Clarify this point, please, because I'm not sure whether you have done things exactly this way. Refer to your mobo manual on p 32. It specifies a process using the F12 key for a "short cut" to choose a particular boot device, but cautions you that this process is NOT a permanent change to how BIOS' default boot device is set. So you can use this to specify that the machine should boot from a particular USB port for THIS boot only, and ONLY if you already have that USB stick containing the Windows Installer already plugged into that port. You would have to re-do it this way every time you try to boot from that stick.

When doing things this way you really should verify exactly WHICH USB port you are using. Your mobo has several on its back panel, and the F12 process may offer only one or two of those a possible boot ports.

Never even considered that there could be a wrong port. I’m using a Gigabyte B650 X AX and plugged it into a USB 3.2 on the back. When turning on my pc it boots into easy mode of the bios in which there is simply a panel that states boot order which I can double click on and reorder the devices there. I only have one visible device though for the boot order atm anyway so that’s what it defaulted to.

 

[Paperdoc]

So, instead of using the Boot Device selection screen that pops up, have you tried using the F12 key to get to a different screen to select a device for this THIS boot only?

Yeah I think I know the issue now , I wasn’t using the instillation media to make the usb a bootable drive, the problem I’ve got now is having no way to download said instillation media as my crappy laptop doesn’t have the 8gb of space in the c drive available to do so. PAIN

Maybe you can do that job on someone else's computer you use temporarily.
