PC se nezapne, pouze pípá
Zdravím, mam problém s PC.
Po zapnutí tlačítkem na bedně se nepustí zdroj, pouze zacne v pravidelných intervalech blikat cervena (tusim ze HDD) LEDka. Takže asi simuluje beep kod. PC nejde vypnout klasickým podrzením tlačítka, musel sem ho vypnou vzadu na zdroji. Deska je Asus P5B-e.
Zdrojem to neni, ted tam mam Energy Knighta, zkousel sem tam i Fortona. Jedina další komponenta ktera byla odzkousena je grafika.
Muj predpoklad je ze to odnesla zakladni deska.
Druha moznost jsou pameti, mam tam 4 moduly, ktere jsem jeste netestoval (nechat pouze jeden modul atd.)
Omlouvam se za kuse informace, PC "testoval" pouze bratr, ja mel dovolenou a vratil se vcera.
Proto toto vlakno, kazda rada dobra a bez pristupu k netu tezko neco vymyslet.
Za pripadne reakce predem dekuji

POST ABCs
The computer power-on self-test (POST) tests the computer to make sure it meets the necessary system requirements and that all hardware is working properly before starting the remainder of the boot process. If the computer passes the POST the computer will have a single beep (with some computer BIOS manufacturers it may beep twice) as the computer starts and the computer will continue to start normally. However, if the computer fails the POST, the computer will either not beep at all or will generate a beep code, which tells the user the source of the problem. If you'd like to learn more about the POST as well as how the computer works see document CH001263.
The steps of a POST
Each time the computer boots up the computer must past the POST. Below is the common steps a POST performs each time your computer starts.
Test the power supply to ensure that it is turned on and that it releases its reset signal.
CPU must exit the reset status mode and thereafter be able to execute instructions.
BIOS checksum must be valid, meaning that it must be readable.
CMOS checksum must be valid, meaning that it must be readable.
CPU must be able to read all forms of memory such as the memory controller, memory bus, and memory module.
The first 64KB of memory must be operational and have the capability to be read and written to and from, and capable of containing the POST code.
I/O bus / controller must be accessible.
I/O bus must be able to write / read from the video subsystem and be able to read all video RAM.
If the computer does not pass any of the above tests, your computer will receive an irregular POST. An irregular POST is a beep code that is different from the standard one or two beeps. This could be either no beeps at all or a combination of different beeps indicating what is causing the computer not to past the POST.
If you're receiving an irregular POST document CH000607 contains all the steps a user can do to resolve the issue or help determine what hardware has failed in the computer so it can be replaced. If you're getting a beep code the remainder of this page contains a listing of each of the major manufacturers beep codes and what they each mean.

Pane, hluboce pred Vami smekam..
Je to opravdu presne tak jak jste to popsal. Kondenzator u SATA portu se nafoukl smerem nahoru. Pri bezne kontrole nepostrehnutelne, ovsem pri vytahnuti desky z bedny a blizsim prozkoumani je jasne poruseny vrchni "svar" kondenzatoru.
Takze se pokusim sehnat stejny kondenzator, kdyz budu uspesny kamarad elektrikar se to pokusi prepajet. Moc tomu neverim, ale za pokus nic nedam.
Jeste jednou diky za pomoc a rady !

a slape. ten kondenzator je urcite spatny, ale na doziti pc (cca 6 mesicu) bude muset stacit, lepsi sem za tak kratkou dobu nedokazal sehnat.
jinak vyborne vlakno k tehle tematice je tady https://www.svethardware.cz/forum/showthread.php?t=14302
diky za radu, dal bych ti bod reaktore, ale mam pry malo prispevku.
