    Hello !
    I have a problem.. Because my computer does not connect to the monitor. Although the monitor connects to the laptop and the computer does not? The problem has been there since I built the computer.
    Equipment :
    - Graphics Card GeForce 7650 GS_256 MB_DVI_HDMI (New)
    - Motherboard MS-7255_C2D_DDR2_PCI-E_SATA_IDE_LAN (New)
    - 10Gb and 40Gb drive (from an old computer)
    - Ram 1 Gb (from an old computer)
    - Intel Pentium 4 3.00 Ghz processor (from an old computer)
    - 350 Volt ATX PSU (Borrowed for test)

    The monitor generally works because the LED is on and writes on the monitor Testing...
    I tested and the board reacts to the removal of the ram (beeps) and the fan on the heatsink spins, so I think everything is ok with the board.

    4 Pin 12V connected?
    This board has a VGA integrated, have you checked it on it?

    Yes, this pin with 4 pins connected and the other pin with 20 pins or something.
    The cable will not go in, because both have contacts :P

    Can you specify what is connected?
    Remove the graphics and run on the integrated :D

    Yes, and what do I connect the monitor to :P ?
    The contacts in the cable are standing, i.e. normal contacts and the input also has contacts in the board, so if I only put it in the graphics card, I can :P

    ;o Then you are not talking about the integration, but about the COM port:
    The computer does not connect to the monitor - anyone know what happened?

    The input to the integrated card is blue and has no "standing, i.e. normal contacts", only holes :)

    The computer does not connect to the monitor - anyone know what happened?

    Plus they have names...
    The one with the holes (input in the graphics card) is a female port, and the plug from the monitor (the one with "standing plugs") is a male one. Just like in biology :D

    This is the first thing...

    The power of the power supply is expressed in WATTS (W) .
    By the way, we provide the brand of this equipment.

    Connect to this input which is marked in the picture:

    The computer does not connect to the monitor - anyone know what happened?

    And one more thing... if you already have something Volts not Volts

    I'm a layman, but these things are good to know :D

    Eh, you break me down such things, it's true that it's worth knowing, but you didn't help me anything ... Because I know where the cable connects. And such an input I have only on the graphics card, not on the motherboard. So maybe someone has any suggestions other than a lecture not needed...

    Connect the monitor to the white DVI socket on the card using a D-SUB-DVI adapter or a DVI cable if your monitor also has one. I recently got 2 cards that did not send a signal through the D-SUB connector.

    I don't think my monitor (Belnea) has such an input and in addition I don't have such a cable :( ?
    Maybe some other idea?

    DVI to DSUB adapter. another idea - replace the graphics.

    This card is new and I will not exchange it for a new one .. So thanks for your help but I will not use it ;P
    But even if you say an adapter, I'll try it :)
    I'm going to buy an adapter and see if it works.
    Or maybe someone else has another idea?

    And this adapter will fit link ?

    It may be new but it doesn't work :cry:
    The hdmi - vga adapter and if it starts on the integrated one, it stays
    damaged pci-e connector
    damaged card
    bios settings - unlikely :D

    Connect another power supply and try to start the computer.

    I had another one but it's a different one because the old one fell apart when I turned on the computer it turned off :P

    On this new equipment, the old power supply turned off?
    Enter the model of this Intel Pentium 4.

    So it started to turn off.

    MS7255 and GF7650 - maybe new, but storage deckchairs. Does the computer boot at all? Does it show any signs of life?

    Connect a stable power supply and clear the CMOS before connecting.

    On the old power supply, the monitor caught and sometimes not. I don't know what caused it? So I bet on the power supply. And that's how it works because the disk works, cooling works, etc. It also reacts to removing the ram

    I only have one working one, so I will connect this one and clear the CMOS :)

    Maybe first measure the voltage of this "working" power supply with a meter - necessarily under load.

    I don't know much about this type of thing, I don't even have a meter, but if it's needed, I'll fix it and measure it :)

    I don't really trust your measurements. If you don't have a meter, you can't measure! It's better to "borrow" the meter with the service - maybe a colleague has a little more knowledge?

    Hardly anyone I know knows more than me ;)
    But I'll buy a cheap meter and do a test like this link

    Could this gauge be? : link

    A friend checked the voltage of the power supply and it's fine, he said :P
    So the PSU is 100% off?
    You have any ideas :P

    Start by checking if you have a working graphics card at all - put yours in another computer or borrow another card and plug it into yours. Check if there is a signal going to the monitor via the DVI connector. You can easily buy a DVI-DSUB adapter in most stores for a few zlotys. Also ask your friends, adapters are often added to new cards.

    It means that you have a different motherboard than you specified.

    ..... I have the one I gave, only instead of the integrated graphics card, I have lan and music :P

    I don't have another card and I'll ask if anyone can borrow it. As for the DVI-DSUB adapter, I'll buy it tomorrow and see what happens ;)

    Hello.

    My friend gave the model of the board correctly (they were produced in two versions:

    MODEL MS-7255 (P4M890M) MS-7255_C2D_DDR2_PCI-E_SATA_IDE_LAN

    MODEL MS-7255 (P4M900M2) MS-7255 + GRAPHICS _C2D_DDR2_PCI-E_SATA + IDE
