    Angry Crosshair V Formula-Z - Not posting Please Help

    Hello,

    A few years ago I got two packages (MB,CPU,RAM) from Overclockers due to moving house and changing jobs I didn't get round to building the entire system. Now, I have some time to build a full system and wanted to use the original parts. However, I did successfully have it running with installed O/S etc, but I moved the case to a different room and added 16GB of RAM. It makes no sense to me why it is not working!

    Symptoms -
    No signal to monitor via DVI-D or HDMI
    Q-Code = C5
    Mobo error light "dram_led" = On constantly
    ROG Connect = stops at Memory

    Hardware -
    Mobo - Asus Crosshair V Formula-Z
    CPU - AMD (supplied in package from Overclockers)
    GPU - MSI R5450
    RAM - 8GB DDR3 Patriot Viper P38G169UR (supplied in package from Overclockers) / 16GB Kingston KHX16C10B1B
    SSD - Samsung 850 Evo 500GB
    PSU - Crosair RM1000x

    Troubleshooting -
    Tried each stick of RAM individually in each slot on the MB
    Checked RAM against QVL
    Upgrade PSU from 650w to 1000w
    Removed BIOS battery from motherboard
    Replaced BIOS battery
    Disconnected every cable from MB, even 24 pin PSU connect give C5
    Pressed clear BIOS button every time when trying something
    Replace BIOS chip on MB

    First of all, I'd like to say that a 1000W PSU is overkill.

    Secondly:
    you had it working before and now it doesn't work: 2 things have happened during the period between working->not working:
    you moved the case and you added more memory.

    Therefore we can conclude that one of those 2 things is what's causing you to have this issue.

    You have 2 different sets of RAM on your MOBO, which is not a good idea. Although I guess you are only using one of the kits at a time.

    Does your setup work again if you use all the original components (what worked before)?
    -> If yes: then your new RAM is very likely the issue
    -> If no: then it's likely that your MOBO got damaged when you moved your case

    As per my notes I did try an individual stick of RAM known working (i.e. 1 stick and 1 brand), still shows C5 Q-Code. that is also trying to clear BIOS inn between.

    I would be suprised moving the case 1 door down while not being removed from the case. If this is the cause it really doesn't say much for the quality of the ROG motherboards.

    You did say you got the components ''a few years ago''. Over time the parts will of course get worn/used, et cetera and maybe, unluckily for you, something on the board was slightly loose or damaged and the fact you moved it caused it to break.

    If everything that was working before is now not working, then it's my logical conclusion that maybe your board did get damaged when you moved it.

    reseat all of your components to rule out a short (loose/over tighten screw) make sure you are using the "correct" screws for your motherboard.
