No start pc and beep

[offshore239]

Hello guys, In the morning I pressed the power button on the computer, nothing happened, I had to disassemble it, and when you unplug the power sata cable, it starts up with errors and with a black screen, what should I do?

@offshore239 , welcome to the forum.

You state in the Subject that there are Beeps.  These could be BIOS beep codes.  If they are there will be patterns, such as, 1 long beep and 1 short beep, 1 long beep and 2 short beeps and so on.  Also, it may emit a LED code.   Listen closely to see if you can hear a pattern to the beeps and let me know.

Hi

That sounded like a 3:2

You get a LONG (MAJOR) signal category, RED LED &

then a SHORT (MINOR) signal category, WHITE LED.

Major – the category of the error; Minor – specific error in that category

The AUDIBLE repeats 5 times, and the VISUAL until power is removed.

Hardware

3.2

The embedded controller has timed out waiting for BIOS to return from memory initialization. Indicates potential memory failure.

1 Reseat memory. 2 Correct memory configuration. 3 Test with known good memory. 4 Replace affected component.

I checked the RAM on another motherboard and everything works, if you do not turn off the sata power then the computer does not start at all

Hi

Do you mean unplug the SATA cable(s).

[offshore239]

But if you turn off this cable, it starts with an error, and if not, it does not start at all

So can you ID it from this page...

The ATX 6 pin power supply connector is a motherboard power connector used to provide +12 VDC to the processor voltage regulator but the 4-pin variety is the more commonly used connector.

This small connector usually attaches to the motherboard near the CPU.

OR is it different, and if so describe it.
