My first pc not POSTing :(

[Matemate]

Hey So I have just finished building my christmas gift PC and guess what no POST.

Specs are the following:

1. Motherboard: ASUS Prime B450m k II (Before you say anything about b450, on paper this mb IS Ryzen 3000 ready it even has the sticker.)
2. Cpu: Ryzen 3100
3. Ram: 1x8g Exceleram Black Kudos 3000mhz and 1x8g Exceleram Black Kudos 3200mhz (these were the only two at a reasonable price hence the mhz difference but they worked well in my old pc)
4. Gpu: ASUS Cerberos GTX 1070 TI - it is used but the guy benchmarked it in front of my eyes before packing it.
5. PSU: Cougar VTE 600, 80+ Bronze 600W
6. Hard Drives: My 2 old 1TB HDDs and my trusty ole 240GB Adata SATA SSD (I know its slow)

Things that happened that might have had an effect on the build:

When installing the CPU Cooler, I accidentally overtightened the top screws too early so they pulled the backplate up so much that the bottom screws were not making contact, but Ive loosened them and eased in the rest till it was balanced and all screws were tight.

 

The computer also killed the electricity in the house the first two times I tried to turn it on but it was the apartments fault, the flat has two circuits and like 70percent of stuff is plugged into the first one because it has way more ouets so it usually gets overwhelmed, so it was on me for not thinking about it but it was not because of the PSU, when using an extender from an outlet of the second circuit it turned on - thats when it didn’t post.

 

I DID unseat and reseat the ram tried different slots, etc. Also tried booting without the graphics card and reseated it aswell.

 

Is it possible that I’ve bent a PIN while fudging around with the cooler?

 

Can it be that since this PSU is only 80+ it and realistically gives out 540Watts that it cant power the system? The box asks for a 550W power supply for the card but Ive read that it should only need the amount under load.

 

Can it be, that even tho it has the no BIOS update needed sticker for Ryzen 3000 my motherboard still needs one?

 

Did I miss something?(Please don’t mind the cables, its not yet managed)

 

 

Any help would be much apprechiated, and I wish yall a Happy Holiday!

1. CHECK THE BIOS

2. tbh theres a really low chance that you damaged lanes

3.idk that brand of ram, mayyyyyybe try some new ram

No, if the CPU was properly seating and inside the socket, it's not possible for pins to bend from playing around with the cooler. It is possible to crack it, though, if you applied too much pressure on one side.

 

80+ doesn't matter as far as wattage output. You should be able to see how much it can actually output on the 12V rail on the side of the PSU. 540W should be more than enough for this computer.

 

That, is certainly possible, yes. It might be ready for the first 3000s series CPUs that came out, but the 3100 came out later.

 

Did it power on at all? Like, were the fans spinning? Is there any boot code? I'm thinking it might be a CPU compatibility.

I believe this motherboard has a bios flashback feature, letting you flash the BIOS without needing to access the BIOS itself. Try that.

 

Then again, Support for the 3100 should've been added in V. 0309. The same as for the 3600 series.

It doesn't hurt to try I suppose.

 

Have you tried with a single stick of RAM ?

Yeah sorry forgot to mention, it is the classic fans spinnin leds blinkin bit no signal case. Yes tried all of the two rams  in all sockets and tried all the outputs! Yes it has a BIOS flash button, I can flash the newest BIOS with it without the need for an older processor?

The ram worked well in my ohter system and its not cheap per say just a bit cheaper than the mainstream ones in my country.

 

But thanks I was scared for the CPU but if its all right, I will sleep sound tonight

I'm not sure how Asus does it, I'm only familiar with MSI's bios flashback, which doesn't require a CPU, RAM or anything other than a motherboard and psu.

 

But looking at it, it should be similar, here's how to do it:

So I flashed to the newest BIOS, still no signal, Tried another RAM - took it out from the PC i got from work - I tried my old video card - a 1050 ti -, no luck either. Just fans spinning, but no signal.

[Matemate]

UPDATE Still no post, I have disassembled the pc to check on the processor, and it is untouched - Ill include a pic of it so you can see, you might spot something that Ive missed - so Im starting to lose faith, the motherboard is working I think since stuff like the bios flash led lit up when I was flashing the bios and such, Can it be the PSU? Can a fresh out of the box PSU just simply not start? How did we get here?

Is that thermal paste I see on the side CPU and socket ? It might be creating a short if it really entered the socket.

What method did you use to apply thermal paste? I'm guessing you've spread it all over the heat spreader before dunking the cooler on top? That method can introduce issues, such as too much thermal paste overflowing on the sides so it's not really recommended these days. A thin X in the middle or a large grain of rice should be sufficient to cover all the necessary parts of the CPU.

 

At this point, I would clean it up as much as I could and probably just return the CPU and motherboard to the store I've bought them. Since either of them can be the culprit here.

I don't think the PSU is at fault, considering you're clearly getting some power.

 

But just as a side note... You DID plug your HDMI cable, into the back of your video card, right? (Not into the motherboard)

You also did open your monitor and switched to the proper source, right? (common mistake)

The picture was taken after I took off the cooler so it probably got there as I was messin around with the processor, since the cooler was stuck in the thermal paste so I had to wiggle it a bit to take off also my hands were a bit thermal paste-y when I put the processor back so it could have got there that way (luckily I had to leave it there since I had to leave to come over to my parents for Christmas eve so the PC was never turned on after this pic was taken so it might still be salvagable), but I was not the one who applied the paste, it is a stock cooler so it was preapplied - I've actually switched coolers on my old PC before so I knew about the dangers of thermal paste but I tought the guys at AMD probably knew whats up . Is it possible that out of the box there was so much paste on the heatsink that it went over and shorted the processor? Also if I check the socket and do see some paste in it is there a way to clean it in a way that it will work again or am I toast? :D 

 

I was trying to get the signal from the back yday night when I posted the original post but since then I've read up on it and realized how big of a dummy I was so I did the usual rounds of checking with the GPU as the output and sstill got nothing, thats why I decided to check the processor and took the picture.

 

Maybe wiping a bit of thermal paste reassembling the PC will help? Or at this point its more likely that I have to return the parts?

Ultrasonic cleaners can clean it right up. But obviously, that's expensive.

 

99% isopropyl alcohol and q-tips might help if it is in the socket itself (don't be too rough, there's probably a video guide on youtube or something). Do check the pins on the CPU and see if there's any paste underneath that links up two or more pins together. Don't touch them, try to rinse them off with the 99% isopropyl alcohol.

Doesn't hurt to try, but at this point, I would just return both the CPU and Motherboard, to be safe. Say it doesn't work, that the PC simply doesn't POST. You get Fan spin, but no video at all. Don't mention anything about thermal paste getting in the socket or anything else that might result in your RMA being refused. (Just make sure you clean it right up, first)

 

 

 

It could technically also be the GPU since the rest powers on, but at this point, who knows. DOA parts are a thing after all.

The graphics card is probably not the problem, because I've tried booting with my old 1050 TI and the problems were the same unfortunately. So the only way is the return I guess, well we'll see,

Update: I've tried everything into my little brothers PC, the Graphics Card the ram, and hooked it up to my PSU and it booted without a problem, so its official its either the motherboard or the CPU, so I've already reserved a slot for returns we'll see what comes out of it. Thanks for all the help, I hope you are having a wonderful Holiday Season!
