Trouble building my computer

Cryomatrix · September 2019

So i started building my comp for the first time without experience. My bro was helping me but i ran into trouble.

I finally think I plugged everything in properly and then i started up the cmop and the fans and colors on MB + GPU started working and then without any sound or anything, it stopped. Now it doesn't turn on.

I have a 750 watt power supply, so I shouldn't have had a problem, any insight?

Thanks

This probably doesnt have anything to do with it, but does your motherboard have a battery in it

What do you mean "Now it doesn't turn on." Like at all?

If that's the case you'll need to reset the BIOS and this usually done with a jumper on the MB. You'll need to look in your manual for that. But before you do that, strip your computer down to its bare bones: if the CPU has built in video, remove your video card. If you have more than 1 drive remove all except for the OS drive. This includes removing any optical drive you may have. Remove any other peripheral attached and if you have multiple RAM sticks remove all but 1.

Now double check all the connections for everything paying close attention to the connectors between your PSU and MB. There should be at least 2 connections: one for the MB itself and one for the CPU which will also be on the MB near the CPU socket.

After you've done that go ahead and reset the BIOS as per the jumper setting from your manual. And let us know how far you get.

You need to give a lot more details really. Full list of base hardware including brands and model numbers. The base hardware: CPU, RAM, Motherboard, GPU, PSU.

It could be anything from a building mistake to incompatible hardware (such as trying to use a 9th gen intel cpu with a motherboard that needs a bios update before it can support a 9th gen).

This kind of issue is usually related to CPU or RAM problems from my experience.

First thing you should do is make sure you have the CPU power cable(s) connected properly. They are usually an 8-pin socket located near the CPU. Just Google Image CPU power socket to see what it looks like if you need to know.

The second thing you should try is taking out the RAM and putting it back in again and make sure it's all tight and clipped in properly. You should line it up above the slots and push both sides down at the same time, not clip one side in first and then the other. Make sure the RAM is in the proper slots too. They should be in slots 1 and 3 if you are using 2 sticks on a dual channel motherboard. Make sure there is nothing in the RAM sockets either. I kid you not, I had a ballache with a system once and it turned out there was a single hair in a RAM socket causing problems.

Make sure the CPU fan is put in the CPU fan connector on the motherboard. If you're using a water cooler you can put a radiator fan cable or the pump cable in the CPU fan connector but you need to make sure the pump has a constant high flow wherever you connect it i.e. not variable speed (that's something to worry about after though and shouldn't stop it from booting up). Some boards will not start up if there is nothing connected to the designated CPU fan connector. The connector should say CPU_FAN next to it.

You may need to reset the CMOS each time you try to boot it up. A quick google search will explain how to do that if you don't already know.

I screwed up the RAM already by putting into slots 1 and 2 and not 1 and 3.

And i'm not sure i did it correctly. the comp turned on but when i conntected it to a monitor it didn't work, then it shut off.

I wish I could teleport you guys to my work place, just waiting for my friends/IT guys to come and help.

I'll look into everythhing again, thanks for your help, you guys are awesome.

Did you find out what the problem was?

It's always good to know what kind of issues new builders have so it can be kept in mind to try help others when they need it.

That shouldn't permanently damage the computer.

Hopefully your IT friends helped you out. @Iselin has some great advice - usually issues like this are something not seated properly or a missing power plug somewhere. Turning on then turning off again immediately is typically a sign of something grounded out and your PSU shutting down on short circuit protection.

The best way to start troubleshooting that, honestly, is to pull it all apart and put it back together. I've found everything from a power plug that wasn't pushed all the way into the motherboard to the video card not locked into the PCI slot to a loose screw that found it's way lodged under the motherboard to CPU thermal paste that had leaked over the edge of the CPU and got into the socket.

And it's possible you could just have bad hardware. There's a lot of different parts in a computer, so even though the odds of any particular thing being DOA is low, given that you have a lot of parts in a new build the odds of having ~something~ DOA is higher than you'd really like. Tracking that down is tough, but not impossible.

Cryomatrix · September 2019

i haven't found the problem, took it into work and the IT guys havent' come by for 2 days, they are slammed.

I may just try to take it apart myself today and see if i can figure it out.

I just tried WoW classic yesterday after Rage Quitting in SC 2 and the game is so goddamn boring, i need my new computer so i can play another game (EU) and stream concurrently while doing it.

Plus, i'm moving into a white theme as I like white computer parts. I'm pretty sure, i connected something wrong.

If you get no power at all when pushing the button in more than likely (assuming you didn't fry some parts) the motherboard needs to be reseated probably as others have suggested. When I did my first PC 20+ yrs ago, I had the same problem, I took everything out probably 4 times and reseated it, eventually it worked, but that was when I was learning to do things for myself and there wasn't much information other than hardware manuals to go by. If you didn't add the case motherboard legs, bumpers or whatever the hell they call them these days, that will cause your short, you want it to be floating above your case's metal.

Grunty · September 2019

also a screw that is loose in the case can cause a short.

alkarionlog · September 2019

ok each pass, first check if you did slot the memorys right, if you slot the memory on 1 and 2 and teh manual says for using the dual channel you need to do 1 and 3 then please do so now, you will gain some speed, if not it will work and only don't use the dual channel tech.

but i'm guessing, since it the first time, you screw the MB direct on the case and not used the screws who come together

https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQMP9Dwxgq31DMTOF0fmUgpXBG_L5Ga0kjz52BN-OkmUtKO1kQA

you should have some like these and these need to be on the case then you screw the MB on top of then,

these last one I menation would be the problem you have, its a newbie mistake, often people forget that

and since you are at it, check the memory like I said, see if you did use the termic paste right and if the processor is placed correctly, processor normally have some marks on then who only let you place then in one way, so when closing if it was too hard to lock him you could have done that one wrong.

I saw in another post that you've got a Ryzen 7 cpu. If it's one of the newer 3rd generation models then your motherboard might need a bios update before it will support the CPU. It's a mistake a lot of people are making right now, even experienced builders, so you shouldn't dismiss it until someone can confirm whether or not that's the problem.

What is your CPU and motherboard? Full name and model number.

I can't even turn the computer on, not sure how to do a BIOS update if i can't turn it on, then again, i'm noob comp builder.

I know that. You'd need another AMD CPU to update the motherboard, or take it into a store that can do it for you using one of theirs, there's no other option. Well, you could return the motherboard and get a different one if you wanted to.

If you tell me what the CPU and motherboard are then I can tell you if that's the problem.

I would leave bios update out for him, if he don't know the basics, chances are he can make huge mistakes on bios updates

Arglebargle · September 2019

This is a useful thread. I've got a mobo/cpu combo that exhibited the same sort of 'no turn on' behavior. While I took everything down to basics to get it to work, I didn't pull it out of the case. Gives me a thing to try the next rainy day.....

If the CPU and motherboard won't work together without it, then he needs to know that.. whether he wants to try the update himself or not.

Finding out if that's the problem is the first thing to do. You know, eliminate as many possible causes as possible. It's PC troubleshooting 101. We don't have much to go on other than he's built a PC and it's not working. Just need to know what the CPU and motherboard are first, that's it.

Down to the simplest, most basic tech-support questions (no offense intended): if you aren't even getting a response trying to turn it on, any chance you flipped the + and - pins on your case Power Button I/O when connecting to the jumpers on the lower-right corner of your motherboard? Any chance the rocker switch got flipped on the back of your power supply by mistake or the cable came unplugged? Any chance your big 20-pin/24-pin ATX connectors are loose or not connected properly to the motherboard or power supply?

Barring those, I'd investigate the motherboard standoffs as others have mentioned. A lot of cases these days come with them pre-installed, but not all of them. And if your board is screwed down directly into the metal chassis, that'll short it out.

EDIT: You can also test your power supply while disconnected from your PC by bridging two pins together to trick it into thinking you flipped a power switch on a computer. WHILE UNPLUGGED FROM THE WALL AND WITH THE SWITCH OFF, plug the big motherboard power cable into the power supply. Get a paper clip and insert one end into the hole opposite the green wire and the other end into either adjacent hole (both ground). Then reconnect the power plug and turn the supply on...if done correctly on a good power supply, your fan will spin up.

Just a heads up, down at the bottom of your parts list there is a compatibility issue between your power supply and motherboard as far as 12v power goes. I'd check all the cabling and jumpers and test your supply, but if everything looks good, that could be your culprit.

I suggest, take that motherboard "Howto" manual in-hands, and read it step by step while in the same time, you assemble your computer.

It helps a lot!

Well it's a 570 MB so you can disregard whatever has been said about needing to flash a new BIOS. 570s support the 3700x.

And the 3700x unfortunately doesn't have a GPU so you will definitely need to have your graphics card in as part of your minimal build for troubleshooting.

And as I said in my first post you'll need to clear the CMOS with a jumper since when it shuts itself down as it did when you first turned it on. It acts as a kind of digital breaker/fuse... which is probably why it doesn't turn on at all now and won't until you reset it with that jumper.

You'll find that on page 39 of your manual and if you look further down that page you'll see that your MB has 4 debug LEDs that let you know whether your CPU, RAM, Graphics card or SSD fail or are not detected on boot.

Not me lol. I've just been building my own for about 25 years so I've made every mistake imaginable and learned to recover from them.

Your manual was easy to look up since I also have an MSI MB and I know they have them as PDFs on their site - most MB manufacturers do.

And I'm also about to start building a replacement for my aging 4770k system and I'm also looking at the Ryzen 3700x

13lake · September 2019

Btw disregard the pcpartpicker compatibility note, you only need to plug in the 8-pin CPU power at the top of the motherboard, not the additional 4-pin, that one is useless and irrelevant outside of extreme overclocking. the new ryzen are very power efficient.

Idk if somebody mentioned it and i missed it but, as first thing you need to do is double check all your headers and double check you didn't wrongly connect the indicator ones, page 6 of the manual.

And then go through the DEBUG LED on page 39, as someone mentioned above.

If the debug led doesn't help, remove all the parts except the power supply outside of the PC and try again, just in case.
