    System Details:


    MSI H81-M33 board

    I7-4790

    16gb Ram

    Attempting to use on board video which has vga and hdmi


    So I recently built my son a Ryzen 2700 system and took his working mobo and processor out and into a new case to replace our older pc . The issue is the system starts but doesn’t post. The processor fan runs hard and the system doesn’t post. So today I decided to do process of elimination.. I went to micro center and bought new ram, new power supply, new processor fan / heat sink, new thermal paste, and a new cheap video card. I came home and built the system .... same issue. I tested each part individually, no post....


    I took the processor out, cleaned it with rubbing alcohol and cue tip and used the new paste already on the bottom of the new heat sink I purchased..... same issue, no video. I put the processor in another oem board and did the same process.... no video. I don’t know how, but it has to be a bad i7 processor now, right? Thought and opinions are much needed.....

    Start by doing an out of case build. There are detailed instructions on the guide at the top of the hw forum. Follow the part "You built the system and it will not POST"
    My guess [and it is only a guess at this point] is that either the board is shorting to ground due to incorrect placement of standoffs OR you damaged something while working on the system.
    Processors are actually pretty hard to hurt unless you physically damage it during installation OR overclock/overvolt the processor.

    I’ll try that, but the boards I tried were in two separate cases. So that is unlikely. Different cases, ram, power supplies, etc. I see no visible marks on th processor or the pins.

    Exactly. Did you check each standoff placement OR did you just install the board without checking the placement of standoffs?

    How to properly install a new board in a case;
    1 Remove the IO plate
    2 Place the motherboard in the case. Mark the position where a standoff needs to be installed; use a pencil or sharpie
    3 Remove the board and install standoffs in the positions marked and no where else
    4 Install the IO plate. Place the motherboard on the standoffs and slide into the IO plate. Secure with screws
