mobo help ??????

By blentz

  1. it started out with my psu burning out so i got a new one.
    when the new on was put in no video but the drives all were spining.
    after reading online it seemed to be that my mobo was dead. it was a am-37
    emachines board so i got a used one that was tested, but when all hooked up
    the same thing happend, no video beeps but everything else seemed fine, so i thought i got a nother dead board. so this time i got a new board, not a am-37 but one that would take the amd 2600+ chip i had had from the beginning, and was going to install new software. but once again nothing no video or signel. what is wrong? please any ideas?

    You`ve changed the PSU.You`ve changed the motherboard.Therefore, it must be the monitor cable/plug,the connections to the motherboard,or something else.

    no video is often caused by damaged, dirty, or improperly installed RAM

    remove, clean, and carefully re-seat your RAM

    also, are you certain that your new board is compatible with your old RAM? give us some specs to go by (mobo brand and model, RAM brand and/or model and/or speed)

    also, what brand of PSU did you buy and how many watts is it rated for?

    the new mother board is a K7mkn-64. and the psu is a antec pp-303x 300W.

    I can't seem to find out any info at all about that mobo... who makes it?

    did you table test it before installing it into the case? you should have, but if you didn't then I suggest that you do. this will eliminate a possible short cicuit (i.e. a screw or standoff grounding the mobo to the case where it shouldn't)

    the board is made by 1st mainboard and is a socket 462. just today i tried a new ram stick from work. it did the same thing. and it is not in the tower. i think the only thing left would be the the cpu? but i still get no beeps, and the keyboard is dead too, so what are the odds of two bad motherboards in a row?

    again, I still cannot find any info on that board, there are simliar model numbers on FIC website (if FIC is the manufacturer), but I can't find yours.

    Do you have access to another socketA mobo to test the CPU in?

    I was thinking you may need a BIOS update to run the 2600+, but their CPU compatibilty chart does not list your model number. you can view it here

    otherwise, I would suggest you contact thier tech support here

    hope this helps

    kind of weird but this morrning i took the cpu and ram out and put it back in. i still get no screen but the light on mobo finialy came on the cpu fan started then stoped and it just kept one short beep and one long beep over and over. i had to unplug the psu to make it stop. tried taking all out and back in but the same thing again.

    after pushing down a little harder on the cpu the beeps stoped and all went back to no video no beep no light on mobo no keyboard(num lock cap lock just no lights on keyboard. i think later this week i will take this mobo and cpu and the old mobo to a pro and see what he has to say and let let you know what happens. thanks for the help and peace
