Or by only putting one stick of memory in, or changing the slot you’re using.
I was assembling a computer and everything seemed to be correct, the fan would spin up, I’d get some lights, but there was no image on the screen, not even the BIOS. I saw someone else make this suggestion and didn’t think it was likely to work, but it did. First I just tried one stick, and it booted. Then I tried both sticks and it didn’t work, but I reseated and then it did.
(Also worth pointing out that your motherboard should have diagnostic lights which if you check the documentation may point out which component has an issue)
Thinking about Lemmy’s demographics many here may have heard of something like this, or have more helpful suggestions about troubleshooting which would be welcome. But thought I’d write out a little post about my experience to contribute to Lemmy SEO supremacy.
I call it “re-seating” the memory because it makes me sound like I have an actual clue.
I have half a clue and also call it reseating.
I have 40 years of PC building experience and I too call it “reseating”.
I miss beep codes so you know what messed up.
I think all motherboards support this, they just don’t come with speakers. You can grab a speaker for you motherboard for about $2 or like 100 for $20
Exactly, then having to go through a thick-ass manual to find out what code it is. Oh, I just need to move a jumper…
As long as we’re going for general tips, sometimes it’s as simple as remembering to turn on the switch on the power supply and surge protector/UPS if plugged into such things (hopefully it is)
One time, my brother and I were building a new rig for him. After spending an hour putting the thing together, it wouldn’t boot. Like, push the power switch and NOTHING happened. We called his buddy who’s a real wizard with computers. His first question was, “Did you try reseating all the power connectors on the board?” And that’s right when we discovered we didn’t connect the power for the CPU.
There’s probably a hundred reasons it might not post. One time, my CPU wasn’t seated properly. I have heard RAM is a common way. If you’re using only one stick, be sure it’s in the right slot. Edit: or even with two, make sure it’s the right slots, read that manual!
Multiple times I had issues with two identical DIMMs in a two-slot board, and simply switching both sticks to the opposing slot fixed everything.
Maybe it was a seating issue, maybe it was ghosts. Who knows?
It’s almost always labeled on the mb which slots to use first. And for some reason it’s usually the #2 slots
printers would often start working after an elevator ride, apparently. oh tech support
Blowing on it helps. The humidity in your breath reinvigorates the silicon.
My cousin and I have run into having to clear the cmos using the jumper in a couple of our builds before it would boot the first time too. Not sure why.
If you don’t want to try and find the correct pins to jumper, you can also unplug the pc from power (which it already should be if you’re digging around in it) and pull the little watch battery for about 30 seconds.
This isn’t just for new computers. After a few hundred heat/cool cycles, the ram can become unseated enough to cause issues. Although it’s definitely not as big of an issue as it was a decade or so ago.
Only higher end boards tend to have diagnostic lights.
I would say most mid range boards have diagnostic LEDs now. My gigabyte b450 board has some, for example, which I consider solidly mid range not high end.
If thats true a lot has changed since AM4. Only the pricier B boards and not all X boards (but most) had them when I last kept tabs on the majority of boards. A cursory google shows at least a few solidly midrange boards with lights (and some without) so you may very well be right.
Pretty much all boards will either have lights, beeps, or both. OEM builds will usually have them on the front IO ports (Dell usually has A/B/C lights). I don’t think I’ve ever seen a board with nothing. Some are more cryptic than others (Lenovo has an app for their laptops that decodes the weird noises they make) but they should have something.
In my experience beepers tend to be very simple. My cheap B-board, but major brand (MSI), only beeps when it POSTs. If it doesn’t post then there’s nothing. Good for when you’re using it headless but otherwise pretty pointless imo.
This can be the culprit along with hundreds of others. Another common one in more powerful PCs is your power supply does not have enough juice.
An underpowered PSU will usually show issues when actually running heavier loads, not immediately at boot I think.
I would go so far as to say that 99.999999% of all issues where a new build won’t boot is to just push harder on the RAM.
Been building computers for almost 3 decades now and I STILL am a little bitch when it comes to seating RAM. It is the least expensive component in the case and mobos are literally designed to let you know when you push hard enough but I still will never push hard enough (for all the sticks) on the first try.
I’ve got a computer that randomly reboots itself for no apparent reason once every two months or so. Always outputs some cryptic information about some hardware issue on the following boot. It’s a problem that’s just far enough on the far side of the annoyance-to-effort curve that I’ve been just using it that way for years now without figuring out what’s wrong with it.
Well, the real YSK is that memory and expansion cards have distinctive positions they should take within each slot, with a detente that holds them in place. Your system will only work reliably if the devices are fully seated.
When you first assemble the system, plug and unplug each item several times so you get the feel of it. There will always be a distinct detente when the device is fully seated. It’s a lot easier to do this exercise with everything out on the bench, rather than mounted in the case when it will be a stone cold bee-atch to reach in and reseat the parts.
and it takes a lot more effort than most people expect to seat the ram and get it to snap into place.
I spent half an hour arguing on the phone with someone telling them their ram wasnt installed all the way to push it down further/firmer and they kept screaming it wouldnt go any further and that i was gonna break their PC. I could tell cause they sent me pics. It was almost all the way, but not quite there.
I gave up and made them to bring it over, and I pushed the ram down with an audible click while staring at him. He had the good graces to say nothing but a sheepish thankyou.
A much dumber reason is because you forgot to install the riser screws before screwing in the motherboard and shorting the entire motherboard against the case.
My best friend did this on his first PC bless his heart lol
WTF case is that?
I dont think I’ve seen a case in 20 years that even had removable/installable risers.
I can’t recall, but he did overspend on his motherboard and it was not damaged by the short. I figured out the issue, and he reinstalled it and it works just fine to this day. That was like 7 years ago.
Hm, they’re removable in about every case I’ve used in the past 20 years. I mostly use Fractal Design cases though, so I suppose it’s something they tend to do.
