    When I start my computer there is no beep and the monitor does not go on until I hit the reset button. Please note that it happens only if I leave my computer off for more than 5 min.Otherwise,everything is fine.

    Hi Jerry,

    First, (of course with the computer powered off) unplug and reseat all the connections at the back of the computer and USB ports. Even reseat the power to the monitor. Make sure the connection from the monitor to the computer is pushed all the way home, then do up the securing screws.

    Going by it only happening if off for more than 5 minutes I'm thinking it may be the CMOS battery.

    Do I have to clear the CMOS or replace the battery? The motherboard is only a month old.

    If the mobo is only a month old I have doubts about the battery being the problem. Not to say it still can't be but let's wait and see what Mattman or others say about my thought on it first.

    I am leaning toward a failing power supply.

    Sorry,I missed the last few replys.

    I have not found that that would be the cause. I thought it was worth trying because it should reset the CMOS. Yes, Jerry if you know how to reset the CMOS it is worth trying. (It will be in the motherboard manual...disconnect all power when you change the jumper...removing the battery for a period of time is the other way to reset the CMOS).

    I think it is most likely that the BIOS is having trouble communicating with a piece of hardware or allocating resources for it, that is why I suggested reseating the connections. Next step would be to remove any added hardware (PCI cards, USB devices, etc), you could also disconnect all the drives. If it boots, add back one piece of hardware at a time between boots to identify which one is causing the problem. If it does not boot, it may still be a problem with the graphics card or the RAM. You can carefully remove those and clean the connections with a soft pencil eraser. Be careful of your electrostatics, ground yourself by touching bare metal (the frame). If you have more than one stick of RAM, just try one and try them in different slots.
    (even try starting with the mouse and keyboard disconnected).
    After that I might suspect the power supply. See if your power requirements are covered by the PSU rating:

    Not likely with a new motherboard, but check for buldging or leaky capacitors (the cylindrical canisters that stand off the motherboard).

    After that...it is a matter of swapping out the major components with known working ones, RAM, graphics card, PSU (Edit: reread, probably not RAM since it works from a "warm" reboot).

    Hope you have some luck.
