First computer build fail, need help

[Atlas270]

Hey guys, random question, but I'm trying to get answers asap. I'm a novice builder and I just built my brother a budget rig, but I messed up several times and can't seem to figure out what I did wrong. With the build complete my motherboard will light up for a second and then turn off whenever I try to power on the pc. I'm in the middle of replacing my cpu as I believe that was the issue because I sort of touched the thermal paste on it when I was installing the cooler. Yea, big mess up for my first build... Without a spare cpu and not being able to test another until the replacement comes in I'm not sure how to troubleshoot the other parts or how to test the actual problem. I'm on an AMD Ryzon 3 2200g cpu with a Gigabyte Ultra Durable GA-AB350M-DS3H Desktop Motherboard. Any and all help is appreciated.

Try reseating the ram and power supply cables

Check all the power connections. I don't think touching the thermal paste would do fuck all frankly, it's not that sensitive.

Unless you mean you got thermal paste on the pins...

Sounds to me the CPU isn't getting power. Did you plug in the 8 pin connector on the motherboard? I've forgotten once and it did what you described

Double checked and seems fine to me. I tried reseating it as well and I still have the same issue. The motherboard will light up and then die.

Are you saying you got thermal paste on the pins? I think you just got a mobo that is DOA.

Is the CPU oriented correctly, and do you have a graphics card installed?

I see. This is my first build so I wasnt sure where the problem was coming from. I tried reseating all my power supply cables with no working solution.

Any way to troubleshoot and check?

Nope, get your RMA started ASAP!

Has your motherboard had an updated BIOS to allow the APU to work?

I was told not to apply any pressure or to reinforce the cpu, however, it fit the motherboard in fine. And no gpu, this is a budget build for my brother with integrated graphics.

A very large portion of B350 boards need a Bios update before an APU will work.

I haven't updated it myself, no. But if you're talking about updating it to be compatible with my cpu, I've been told it comes already compatible with this cpu and has the "AMD RYZEN DESKTOP 2000 READY" sticker on it. I'm using an AMD Ryzen 3 2200g with a Gigabyte AB350M-DS3H.

[dizmo]

Did you check to make sure the memory's on the approved list.

As long as it says Ryzen 2000 ready that's fine. If your sure that your ram is compatible then most likely a board failure.

 

If you haven't yet,  unplug everything not needed to power on, ssd/hdd/fans/contollers the lot then see if it stays switched on, if it does there's a problem with one of those, if not then i'd say RMA the board.

 

If you have access to another PSU would be worth a try aswell.

I belive so.

Do you have all the motherboard stand offs installed?  Maybe a short to the case.

[Dxer]

What exactly happens when you power on?  Will it cycle on and off indefinitely?  Or will it stay off after the MoBo lights up for a couple of seconds?

Also have you tried clearing CMOS?

I unplugged everything except the 8 pin near the cpu and the 24 pin and the case power switch. Now it won't even turn on at all. I also tried to turn it on without the power switch using a screw driver.

All, but one where there is a hole in the case to allow cable management.

The motherboard will light up shortly, then die. It won't do the same until I give it about 5 minutes and try again. anything before that time and it doesn't respond at all. Now after unplugging everything except the 24 pin and the 8 pin power supply cables the board isn't responding at all.  and I have not tried that yet and am currently looking up what that even means.

[Dxer]

This might be a silly question.  Is your heatsink/fan secured properly?  Almost sounds like an overheating issue if you have to wait 5 minutes

for the computer to respond again.

I'm not sure, but none of the fans powered on in the first place. I was sure that at the very least my cpu cooler was pluged in properly, but again, none of them worked from the start. 

[Dxer]

And did you make sure you plugged the CPU fan into a CPU fan header and not a chassis fan header?

 

Sorry if some of these questions sound trivial, but sometimes it is something very simple.

Yes, right above the ram slots. And honestly, I'm looking to anything that could be the problem as well. Much appreciated help.

[Dxer]

I am not sure what else  you have tried yet.

Clear CMOS.  There is a jumper just next to the heatsink that says Gigabyte on it.  Take a screwdriver and short out those two pins for a couple of seconds.  That clears the CMOS.

Try using only one stick of RAM and try each slot.  Then do it again with the second stick of RAM.

Post a high res picture of your motherboard installation, you had a partial picture above, I just want to see it all in one pic.

Is a graphics card installed?  If so, remove it. Just use the on board Vega graphics for now.

If you have a multimeter, try measuring the 5v and 12v from one of your molex (4-pin power connector from the the PSU) connectors if you have one available.

 

Kinda running out of ideas.  If all that fails, time to RMA the board.
