    I have an AOpen vKM400Am-S Motherboard, when i turn it on a red light and cpu fan turns on but no video to my monitor,i checked if my video card works on a difrent pc and it did, my pc wont turn on

    this caused by RAM error, open your computer, disconnect ram, turn on your computer?is computer beeping, 1 long and 2 short beep??if yes the problem is come from your ram, clean your ram connection then connect ram to mother board, turn on your computer, is the video come to screen??if no, try to connect another ram to your computer, for sure use new ram
    i hope this helpful
    thank you for using fixya

    If functioning correctly, your motherboard will support the following types and speeds of CPU's

    • Supported Processors:
    • AMD Athlon XP/Sempron/Duron
    • Socket A processors
    • 200/266/333 MHz FSB
    So likely it tops out at Athlon XP3000+ /333MHz
    Sempron 3000+ socketA/462.

    I would like to find the spec manual and what cpu slot it has.

    Hi there,
    I tried to get the exact link, but the website will not allow it.

    Go to this page, and put in your model number, and you will find it really easy.

    This board is a socket A for AMD processors.

    You will need adobe reader to get this manual.

    Memory +cpu upgrade

    No to the cpu you selected. Board would not support that cpu. The RAM you selected would probably work but for how long I couldn't say. With prices pretty low right now it would probably be better to purchase a new motherboard, cpu, & RAM. Hope this helps.

    Change the battery

    It's the round shiny chrome disc on the motherboard. Remember if you change it you will need to reset the cmos in the bios.You can contact me and I will walk you through that part.
