Power_LED Buzzer on Mainboard continues to beep every 3 seconds fans are operating but system doesn't boot or show nothing on monitor(which is ok)
well you didn't say what the beep code was, is it just one beep every three seconds? Or is there long beeps, short beeps, and long and short time between them before they repeat?
If it is one, beep, every three seconds and the beep is one second long, there is a problem with a connection somewhere. Typically it happens in older computers that are in dusty environments. You can try to (only if your comfortable with how to do it) unplug the memory modules from the motherboard and keep track which socket which is plugged into, and mix them up so they are in different slots from their original positions, then try to reboot.
If that does not work and there is no display at all (even POST information) it could be a bad card (modem, sound, video, etc.) remove all but the video cards and try a boot again, if you can boot then plug only one card in each time you try to boot and when you find the offender replace it with a new one (that is if you use that card, if it is a modem and you do not use dial up internet you do not need the modem card plugged in.
But one, one second long beep every three seconds typically means there is a connector problem somewhere, if the computer is older carefully clean out the dust and unplug and re-seat all of the connectors and hopefully that will solve your problem
