First Build Problems

Build a PC

  1. Hi guys this is my first post, have just finished putting together my first pc.
    - when I turn the pc on, the lights are flashing, fans are spinning, (I do not hear a BEEP however) keyboard and mouse lights are on as expected.
    The problem is my monitor is not connecting to the pc. "Signal not found" is the message that appears on the monitor before it goes into sleep mode. I cannot see the BIOS and therefore cannot install my Windows 8 OS.

    The following is the list of components in my pc build:
    - Asus P877-I H77 Motherboard
    - Intel i5-3470 LGA1155 CPU 3.2Ghz
    - Corsair 8GB Vengeance DDR3
    - Gigabyte ATI HD 7850
    - Western Digital 1 TB SATA3
    - 500W Corsair CX500 PSU

    - Windows 8 64-bit

    I have tried using VGA and HDMI cables, I have tried using different monitors which have worked fine when I tried connecting them to my laptop. Therefore I determine there must be something wrong with my pc but I cannot pinpoint the problem.

    Any ideas or suggestions will be much appreciated.

    Double check all connections on your board. It's not hard to miss a cable and forget to plug it in. It also isn't hard to plug some cables into the wrong spots on the MOBO. Make sure everything is secure and in the right place.

    I think it is a connection issue like Blkfx said.

    Try it without the video card installed, see if the screen works connected to the motherboard video output from the iGPU.

    Does that video card require a separate power connection?

    Yes, the 7850 requires a separate power connection.
