well my rebuilt computer failed to post. now I have to wait for technicians to diagnose.. we should start a betting market... momory mismatch? power supply? some cable not seated?
Discussion
I always bet on memory not being fully seated or in the wrong slots
what does the post code say
90210
fans spin and rgb lights, but no beep, no display, USB keyboard numlock not working. So it didnt pass POST, no display so no bios or messages.
Does it have onboard gfx & hdmi? Might want to try that in case you haven't yet. Sometimes the trouble is insufficient power to the graphics card…
I am using just onboard until that works then I will do the gfx card later.
Either PS or cpu not seated
PS is best guess. maybe one rail is failing. CPU does not seem possible to seat wrong in AM5 socket, but maybe I will learn
I've also seen faulty video cards short out a main rail. Try pulling the video card.
I've also mixed up peripheral cables from a different PS that will short out the outputs if you try to use them interchangeably
Even two of the same brand, but different model PS could have different cable pinouts
There is no video card installed. There are no peripherals installed. There is no SATA device installed. I did plug in the power connectors, but I think they only fit one way.
Also it is at the shop since I gave up. I'll let everybody know what it was when I get it back (hopefully today).
it's probably a busted motherboard
haha i used to work at UMart back in 2007 for a 6 week stint while their usual warranty clerk was on holiday back in china... failing motherboards was pretty common... there is also it could be the PSU is not feeding enough power through because it's faulty also
if the shop is decent they have a whole set of known good components to pair it with and will isolation test all of the parts and identify which component is broken
it can even be a dead cpu, that happens sometimes too, but the motherboards are probably the most complex and most likely therefore to fail
Yes the motherboard is a good guess. I don't know why motherboards are still so fragile. Why can't they make circuits that are embedded deep inside a metal heatsink with no exposed fragile bits? You'd be able to play football with something like that without damaging it.
CPUs tend to not be dead because as higher value products they get a lot of testing, also they have to be tested in order to classify which model they are (they make them all the same, and then via testing decide which cores to keep and which fuses to blow). They are also packaged very well and in general are kinda hard to fry these days even when not cooling them properly.
they sure aren't as fragile as they used to be, it's just the sheer number of components, and the nature of statistical sampling used to test stuff
the failure rates can be reduced by testing a larger number of the production batch but in doing so you have to raise the cost, because very often the tests are destructive
the same thing with CPUs, they actually just make a batch of chips, test them at baseline, and then escalate until the failure rate passes a percentage and they clock the whole batch at that same speed they got the less-than-target failure rate on
so, i'm sure you can see the combinatorial problem of the thousands of components in a CPU, if the chances are that 0.001% for each component to fail it doesn't take many pieces until you have a high probability
there is your problem - you're using AMD
The problem is that an Intel CPU might one day explode in my face if I were to criticize Israel too harshly. Not only does Intel have big operations in Israel, when I lived in California everybody that I knew who worked at Intel was Jewish. Of course that doesn't matter to me (being Jewish that is, those people were my friends (being tied to Israel does matter to me)), but maybe it does to you.
Also, while AMD has lagged behind Intel for most of history, several times it has come neck-and-neck or even beat Intel. Right now AMD products are almost neck-and-neck.
This isn't to say I trust AMD. I think they have NSA backdoors just like everything else. For example, when the Zen3 came out, the RDRAND instruction was giving all 1 bits and they had to issue a microcode fix. That should be impossible, RDRAND should be pulling random noise from a diode loop. So it led me to believe there is a backdoor to 'disable' the true randomness whenever government targets you.
We have to live with difficult decisions like this. Maybe one day the Chinese will catch up and offer a PC CPU. Then someone could build a PC with two processors, an American and a Chinese, and have the processors audit each other.
interesting - i didn't know a lot of Jews worked at Intel's California offices.
keep in mind Windows is now migrating to Qualcomm Snapdragon X ARM Architecture CPUs
unfortunately i already got both a new desktop and laptop before Spandragon X machines came out
as for AMD they have beat Intel handily on several occasions but even when they were beating Intel companies like Dell were reluctant to use them because performance isn't everything - driver support can be more important - but even more importantly companies like Dell simply don't want to sour their relationship with Intel over an accidentally excellent AMD cpu that occasionally does come out
the other issue AMD had on my watch is they announced a CPU ( Threadripper ) and many brands released motherboards for it but then AMD never released the CPU to consumer market - only to OEM. all those motherboards became useless. it is unbelievable to me that a company can screw their partners like this. then they recently had an issue with CPUs failing because they were pushed too hard ( stock ). and probably the most sketch thing they did was they officially approved several coolers for the Threadripper that didn't even cover the die area, but AMD said that against all odds they somehow worked so they got approved. this kind of asshole behavior from AMD reminds me of Tesla where Elon bragged about using non automotive grade screens ( because they are cheaper ) to get that marketing buzz about having 17" screen in a car, before those screens started failing.
sadly a large majority of people will always buy whatever offers the most performance per dollar. personally i would rather buy from a company that does things right even if it costs more and isn't the fastest.
in any case both Intel and AMD are history. it's on to Qualcomm and Nvidia now.
anyway if you're boycotting Intel as part of BDS because of their large presence in Israel i can certainly accept that reason
honestly X86-64 architecture that both Intel and AMD run on is outdated garbage. Apple has the best silicon right now.
Running Linux on a new Macbook would be cool, but i am not into Linux and Apple OS runs neither CAD software i use nor Games i play.
but in terms of computing power per watt Apple silicon ( and Qualcomm Snapdragon X ) beat the shit out of X86-64 regardless of model of Intel or AMD cpu.
Snapdragon X ( even in Elite spec ) is still somewhat of an entry-level CPU while Apple chips range from entry level to high-end - certainly high end by notebook standards.
I would give Snapdragon X a few more years to scale up to higher performance levels but Apple silicon is ready, at least for notebooks.
apple is very very good but you are then dependent on a single supplier. RISCV is best performance per watt, but that happens at very low watts... milliwatts.
yeah Apple can add or delete products from line up at will and they have switched CPU architectures in the past as well ( they used to run IBM power PC ) so they definitely can't be relied on.
or rather they can be relied on to produce a great laptop but not anything else and you can't know what CPU the laptop will use either.
apple is for people who need a $4,000 laptop machined from a single slab of aluminum ( oh no sorry, i meant to say "aluminium" ) to answer e-mails from starbucks.
then again we have a 9,000 lbs, 1,000 horsepower Hummer EV so that 5'2" women can have means of getting to their Zumba class two blocks down a suburban road without a single crack in the pavement.
I had a board that had some small leds near the front panel connectors which lit up differently to indicate errors like poorly seated ram. Anything like that?
No LEDs. No flashing LED. No multiple beep signals. Nothing at all in the manual about troubleshooting. This is a cheaper motherboard that didn't bother with any of that stuff.
Jumper slipped out of place. 😜
Can you plug it into a monitor/tv to test?
using AMD and wondering why it doesn't work is like living in a communist country and wondering why the shelves are empty
because nothing is free that's why
and it's cheap for a reason
back in school, they told me that more then 80% of all problems is because of power supplies.
betting on that ;)
The technicians say that it needs a BIOS update, and the lesser techie was told to let the greater techie do it, and he comes in on Monday. (The reason I can't do it is that I would have to install a 7000 series CPU, do the update, then put my 9700X back in, and I don't have a 7000 series CPU.
The board is for Ryzen 7000/8000/9000 but was initially released for 7000. I thought I got a rev2 but I got a rev1 and it has an old BIOS.
So the following guesses were wrong:
* Momory mismatch (and misspelling)
* Power supply
* Some cable not seated
* PS or cpu not seated
* Busted motherboard (close)
* Busted CPU
* Jumper slipped out of place
* Standoff in wrong place shorting the motherboard
* CPU pin bent

:) good to hear you are getting it sorted Mike!
my gigabyte board can do what’s called a qflash - it can flash the bios blind without a compatible cpu available, and pc not posting. There’s a physical button to trigger it on the motherboard, assuming you have a usb drive with latest bios on it in the qflash marked usb port.
