The issue I am having with one of my computers is that in the morning the Computer will not power up properly, the monitor is on and displays the box to let you see that it is working properly, but is not connected to an input source, after a few times powering up and down the computer, it will eventually work. I have replaced the monitor just to see if it was a problem with the connection, so the next thing I can do is replace the motherboard, which has the video card built in. If anyone has any ideas on what this problem is, I would really appreciate it. Normally I would simply solve the problem and go about my business without worrying what the actual details were, but this is a special case in which I need to know what the problem was. Thanks for any help anyone can give me.

If possible, install a spare or borrowed video card(You may have to disable the onboard video adapter either with a MB jumper or in BIOS).
If that fixes things, then the onboard video adapter is bad.
If no luck, then check the CMOS battery for the correct voltage(3V).
If the voltage is ok, then turn off the power, disconnect the power cord, and clear CMOS either with the MB jumper or by removing the CMOS battery for at least 30 minutes.
If that does not work, then do a barebones installation by connecting only the power supply, MB, CPU, memory, monitor, case speaker, and power button, and make sure all connections are secure.
If that works, then reconnect/reinstall all other drives and cards one at a time until the problem resurfaces. The last item installed is the cause.
If the problem still happens with the barebones installation, then place the MB on a piece of cardboard.
If that fixes things, then check for a loose piece of metal under the MB.
If there's none, then install paper washers between all metal standoffs/screws and the MB. A manila folder makes excellent washers.
If no luck with the MB on a piece of cardboard, then either the PS, MB, CPU, or memory may be bad.
Remove and reinsert the memory a few times making sure it's firmly seated, and install the memory in different slots. If still no display, then swap out the MB, CPU, memory, and video card to find out which one is defective.

Recentlty I had exactly the same symptom on my work PC, turned out to be a damaged Athlon XP2.2 which obviously had a fault as it was posting as a Duron 1800 anyway.
I have also seen failing PSU's create this same fault.
It would be rare for just the video to fail (onboard) but I guess cheap to just fit a used 4/8meg PCI card instead of replacing the mainboard if other suggestions don't work.
