I have a PC that when you power on, there are no beep codes, there is no sound coming from the hard drive and nothing displays on the screen. When it worked before you have to leave it on in order for it continue to run, but when you shut it off it will not work. Does this sound like a mohterboard issue or could it be something else?

Could be the hard drive is either failing or not getting enough power to spin up until it has been "on" for a while. Can you turn it on, wait for a minute or two, then CTRL+ALT+DEL to reboot and see if it works then?

Could be something as simple as the BIOS battery. Could be lots of things.

So, you need to be more specific with your equipment specifications and OS so we can help track down the problem.

The thing is, when dealing with no power there are multiple things at issue there. Have you tried unplugging all of the peripherals. IE. Printer, HDD and anything like that? What i would do is strip the computer down to the hdd, memory, cpu and power supply. See what happens. If nothing, strip out the memory, see if you get beep codes at all, check for lights to come on.
Like I said, could possibly be any of the peripherals, Cards (network, video, modem) and it's just hard to tell until you've worked it down to the main components.

Thanks for the help. I found that it was the power supply and not the motherboard itself.
