Power Supply Unit is good I'll try it with bios, so I'm reporting Posted after 29 minutes 49 seconds: I returned to the f3 version But the same case, even it happens without a bios chip removed from the board |

The Motheboard stands at my service desk. Nothing is connected except power and processors I have a lot of experience with the service, this is one of the hardest things. I do not have an oscilloscope not schematics motheboard Posted after 6 minutes 32 seconds: My opinion is that there is a defective nort bridge or ite8718f-s chip ? |

Good. I correctly understood that the motherboard turns off after 2 seconds after power on? |

Motheboard turns On and remains on,but as I listed on the Pci tester, the LED diode reset turn on and turn off each 2 seconds Posted after 5 minutes 1 second: Slave82 писал(а): Motheboard turns On and remains on,but as I listed on the Pci tester, the LED diode reset turn on and turn off each 2 seconds

It is normal ? Without RAM - abnormal state of the PC... |

What voltage on cpu cores VCC_CORE (on chokes or capasitors)? |

I changed the other north bridge, ITE chip I'm not smart anymore what it might be I had such a case with bios, but I both removed both the chip and reprogrammed the bios dam from the official site Did any of you have this case? Posted after 7 minutes 10 seconds: Is there any schematic for this motheboard? |

Check signals on 61-65 pins ITE. Unstable or change of the logical level within 2 seconds? |
|

I replaced the ITE chip, the result remained the same. I do not have an oscilloscope, as I wrote in a previous post I think the socket is defective, if there is another idea, I had a pair of plates with this kind of malfunction, but I did not manage to fix a single one Posted after 1 minute 58 seconds: Another question for the experienced, should the ITE chip be from the same board and version? |

Цитата: Check signals on 61-65 pins ITE. Unstable or change of the logical level within 2 seconds? Check with a multimeter in DC voltmeter mode |

remove the radiators from the bridges and take a photo in good quality near them. I'll show you what capacitors you need to check for leakage. maybe a problem in them. |

Не совсем понял, но он походу без памяти ее запустить пытается... И не факт что у него тестер рабочий |

What is the voltage on the VCC F_USB1 or F_USB2? Capacitor EC9 where? |

4.97v the capacitor was damaged during the transport of the board But it's not up to the capacitors I found a malfunction The bond is as if it was cut, so hard it can be seen with a magnifier, here are the pictures attached |
