New mobo, used CPU - Fans work, but no Video or BIOS

By salmanal ยท 6 replies

  1. My old cpu melted off the mobo due to heat and continuous usage
    where I live.

    I purchased a new case with a PSU, new FIC KT-748 mobo,
    and want to use a used Athlon 1.2 cpu.

    FIC will not respond to support email and their support # is always busy.

    I think I connected the front panel switches properly because
    the system does respond when I press the Power switch.
    So I have a new mobo, PSU, and case; used RAM and cpu.
    The cpu came off a HP that had a damaged mobo, so I thought
    the cpu may still be good. The RAM came out of my old melted
    system (I also have another stick in case).

    When I press the power switch, the case fans, psu fan, and the
    cpu fan are working. I just get nothing on the screen, not even BIOS.
    I reset the CMOS. I get no beeps after letting this run a few minutes.

    I'm starting to think the cpu has gone bad, but I 'm not sure.
    If I need to, I can buy another cpu easily.

    Thanks in advance for your response......

    Have you tried the memory in a different slot? Swapped the memory with the other stick? There are many variables that can come into play. And you are correct it still may be a bad CPU. But take all added parts out and see if you get any beeps with just the CPU in place.

    Best bet is to take off all connections except the power connections. I mean all of them including the front panel connections. Take off all the cards such as modems and video. Disconnect all IDE and SATA cables.
    Now try and restart by touching the two power button connections with a screwdriver to jump them.
    If it works and gives you a POST response, put back the video card. Try again. Keep going and adding bits until you find what caused it.
    I had a board like this where a friend had connected the HDD LED cable to the reset button - this means it was on permanent reset so did nothing.
    Is the board shorting out on a mounting stun underneath?
    Are you sure the board will run the chip you have?
    hope all this helps!

    eBay, Here I Come.....

    With the PC stripped down to the PSU and RAM, I still get no
    BIOS or POST.

    inComp USA is a 3-minute walk from my front door,
    but they push 64-bit processors. My versions of Linux
    are 32-bit. I call them inComp because for years, most employees
    have been as knowledgeable as the average
    Radio Shack employee. Recently, I wanted some
    thermal paste for my processor and the employee told me,
    they wouldn't carry anything like that. Odd for a place selling
    CPUs, heat sinks, and Mobos. I found it there anyway.....

    I would guess the the "new" FIC motherboard is bad before suspecting the CPU. The CPU is used and it may not have been handled that carefully, so it could be bad

    Update: I give up.....

    With a new mobo purchased locally and the CPU (used) still has warranty on it;
    the attempted build show no BIOS screen or won't give any type of POST.

    Reseated RAM and CPU, disconnected everything except my nerves. (smile)

    I'll just need to buy a "barebones" With DR2 and a 64-bit CPU
    to replace my melted system. (I'm new here and underestimated
    the heat)

    Take Care All,
