    Asus h81m-c - no signal detected / no bleep error code


    Hi all,

    Having issues with a ASUS H81M-C motherboard which shows no signal detected on boot.

    Equipment
    ASUS H81M-C MOBO, CORSAIR XMS3 4GB RAM 1600MHZ, INTEL G3258 1150 CHIPSET, 120GB SSD, BE QUIET 300W PSU

    notes
    no error bleeps on boot
    no signal detected on screen
    cannot access bios
    reset CMOS - no success
    moved all parts over to gigabyte mobo and all works well.
    removed RAM from board and booted but no error codes from this either??

    Whats frustrating is that I returned the mobo to the buyer who tested and showed as working correctly.??

    Im thinking it maybe a RAM issue?
    Does anyone have more experience with the ASUS mobos? Are they funny on RAM types/spec (checked QVL and Corsair RAM that i have picked is not showing)

    I knew i should have stayed with Gigabyte

    any thoughts/comments welcomed

    thanks for viewing :)

    That is a small power supply, and I've never heard of that brand.
    Your symptoms could be caused by a bad or underpowered power supply. Particularly since the motherboard tests OK. Can you borrow one (larger) to test with?

    switched out and used a 600w power supply... and still no post to monitor.

    Yes, just because I never heard of it does not mean it's not good!

    I like to track these problems down through process of elimination. So forgive me if I suggest something obvious. If it's not in your list of things you tried I think we have to eliminate it.

    No signal indicates that there is no output from the video card or graphics chip. The simplest reason for this is a bad cable. So you should test that.

    Your next step would be to check BIOS settings to be sure on-CPU graphics are enabled, or try a (different) video card.

    absolutely fine by me.. :)

    plugged in a graphics card which powered up (fan) but again no output to monitor.
    switched cables using a VGA and then moved over to DVI-D
    Cannot access the bios as no output.

    i am certainly thinking that its a bad board the more time i spend on it... might take it back again with the components attached and ask them to take another look at it.

    When the motherboard was tested by others, did they test it with your RAM or theirs?

    there own ram and cpu. however, i have switched the RAM and both 1600mhz and 1333mhz failed to work.

    also tried components in gigabyte mobo and worked.

    Something is missing. Motherboard tests good. RAM & CPU test good. Power Supply ruled out. Video ruled out.
    Doesn't leave much.

    All the RAM for that board is speced with voltages at 1.65v for almost all 1600, and 1.5v for all 1333. You should check that your RAM fall in there. The CAS Latency should be in the 8-9-10 range.

    Have you tried removing everything from the system except PS, MB. CPU, RAM and Video?

    yes... bread boarded the mobo with minimum setup.

    I've been on the ASUS website and think i might have an answer.

    Will get my hands on an order chip tomorrow and see what happens.
