No display on monitor after installing new mobo

There is no display on my monitor after installing a new mobo, MSI 890FXA-GD70. Everything seems to be wired correctly. Please help!!

  1. Probably a video card or RAM error.. Which are the rest of your system components.? Are you sure that every component is in perfect health.? Is there any type of noise (which generally indicates any type of hardware mismatch and/or failure) when you try turning ON your system.?
  2. ^+1 Asking the same questions lol
  3. I have an nividia 465 card that is fairly new, but was working before i swapped mobos. Also, just bought 2 2GB corsair gaming memory because i needed DDR3 for the new mobo. Prehaps I installed them wrong? However, everything seems in working order other than getting a picture on my monitor.
  4. Ok, what is the RAM model you got?

    And again no beeps whatsoever when starting up? O-o
    What psu are you using?
  5. Quote:
    still set to on-board video.?

    No 890FX mobo features on-board video..

    test plug-in video card (465) in another unit to verify if good or not.
    same with the RAM..

  6. my ram is cmxg4gx3m2a1600c9, the corsair gaming series. I was doing some research and realized some memory may be specific to intel or AMD mobos. With that being the case could it not be working because it is specific to an intel board because my mobo is an AMD board. On top of that, would my nividia 465 card not be working correctly because it is socketed to an AMD mobo?

    Also, my psu is the thermaltake 850 watt black widow, so that should not be the issue. And no there are no beeps when starting the comp.
  7. There really is no such thing as Intel or AMD specific RAM. If the sticker on your RAM shows 1.65v, that doesn't mean that you can't use it with AMD CPUs. Though the 1.65 V limitation is specified by Intel, and the RAM manufacturer kept that in mind when designing a particular model, that doesn't mean the RAM can't be used with an AMD CPU, as there is no way for the mobo to discriminate.

    An 850 W PSU is plenty, but that doesn't mean that there isn't a problem. My suggestion is that you work through the troubleshooting gudie (link in my signature) and perform every applicable step; no skipping.

    You may even want to consdier breadboarding (like malmental mentioned, a possible short) to rule out case problems. If you're not familiar with breadboarding, follow jsc's guide (its in the troubleshooting guide).
  8. Hey, thanks, T_T.

    Expanded breadboarding section follows (shortstuff has told me he has stopped supporting the "won't boot" thread :().

    Work through our standard checklist and troubleshooting thread:
    I mean work through, not just read over it. We spent a lot of time on this. It should find most of the problems.

    If not, continue.

    I have tested the following beep patterns on Gigabyte, eVGA, and ECS motherboards. Other BIOS' may be different.

    Breadboard - that will help isolate any kind of case problem you might have.

    Breadboard with just motherboard, CPU & HSF, case speaker, and PSU.

    Make sure you plug the CPU power cable in. The system will not boot without it.

    I always breadboard a new build. It takes only a few minutes, and you know you are putting good parts in the case once you are finished.

    You can turn on the PC by momentarily shorting the two pins that the case power switch goes to. You should hear a series of long, single beeps indicating memory problems. Silence indicates a problem with (in most likely order) the PSU, motherboard, or CPU. Remember, at this time, you do not have a graphics card installed so the load on your PSU will be reduced.

    If no beeps:
    Running fans and drives and motherboard LED's do not necessarily indicate a good PSU. In the absence of a single short beep, they also do not indicate that the system is booting.

    At this point, you can sort of check the PSU. Try to borrow a known good PSU of around 550 - 600 watts. That will power just about any system with a single GPU. If you cannot do that, use a DMM to measure the voltages. Measure between the colored wires and either chassis ground or the black wires. Yellow wires should be 12 volts. Red wires: +5 volts, orange wires: +3.3 volts, blue wire : -12 volts, violet wire: 5 volts always on. Tolerances are +/- 5% except for the -12 volts which is +/- 10%.

    The gray wire is really important. It should go from 0 to +5 volts when you turn the PSU on with the case switch. CPU needs this signal to boot.

    You can turn on the PSU by completely disconnecting the PSU and using a paperclip or jumper wire to short the green wire to one of the neighboring black wires.

    A way that might be easier is to use the main power plug. Working from the back of the plug where the wires come out, use a bare paperclip to short between the green wire and one of the neighboring black wires. That will do the same thing with an installed PSU. It is also an easy way to bypass a questionable case power switch.

    This checks the PSU under no load conditions, so it is not completely reliable. But if it can not pass this, it is dead. Then repeat the checks with the PSU plugged into the computer to put a load on the PSU.

    If the system beeps:
    If it looks like the PSU is good, install a memory stick. Boot. Beep pattern should change to one long and several short beeps indicating a missing graphics card.

    Silence or long single beeps indicate a problem with the memory.

    Insert the video card and connect any necessary PCIe power connectors. Boot. At this point, the system should POST successfully (a single short beep). Notice that you do not need keyboard, mouse, monitor, or drives to successfully POST.
    At this point, if the system doesn't work, it's either the video card or an inadequate PSU. Or rarely - the motherboard's PCIe interface.

    Now start connecting the rest of the devices starting with the monitor, then keyboard and mouse, then the rest of the devices, testing after each step. It's possible that you can pass the POST with a defective video card. The POST routines can only check the video interface. It cannot check the internal parts of the video card.
