My friend lives in CA and built this computer from scratch for me. He used this mother board. I was getting an error on boot up that keyboard was recognized and floppy disc error (80).
Now the computer won't power up at all. I went out and bought a new power supply, but that did not help.

Re: no power at all
Maybe your cmos battery has died. Buy a new one for about $5.00 and replace it. It is the battery that saves the settings for the motherboard but if it is dead the motherboard will get absolutely no power.
When you replace it, leave the power plugged in to the cpu for a couple minutes to charge up the battery and regain the settings and then try to power on the cpu again. If this still doesn't help then check the power supply.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

You have tested the variables if still not working you have a bad mother board.
contact foxconn for replacement.
You have given little information, but to me it sounds like your hard disk is failing. I would try to get the drive imaged to another one, and replace the drive before you completely lose all your data!
If you have another computer that will hook up to the internet, download a copy of any live Linux CD (UBUNTU) and see if the computer will boot with that (you download a image file that burns to a boot able cd). If it will boot with a live CD, then you have a Hard drive / operating system problem. If it will not boot from that, you have a mother board problem. Start removing things from the motherboard, unplug and remove everything then plug hook up things one at a time.
From the description, sounds like you have two failures, both concerning the mother board.
1. The connection to the motherboard for the battery is no longer good. Replace the mother board. The points of failure that you have given so far and has not fixed the issue. Battery fully charged, seated well, no change, mother board.
2. Laptop will come on with AC adapter attached but will not boot up; mother board. There is a built in test that you can run, from a powered down state press FN + Power button, this puts this into a diagnostic state. If it does not go into this diagnostic; mother board. The diagnostic is stored in the BIOS, which is a part of the mother board.
3. If the diagnostic runs note any error codes that it gives. They will be in the form off XXXX-XXXX or XXXX:XXXX, where the X's represent a letter or a number. These can be used for further trouble shooting.
My friend, I am glad you have identified your sound card. Remember, when dealing with a computer, it doesn't care what you know about it, the computer must know about it - where ever it is.
Please check your device manager to see if the sound device loaded properly and the driver is running. You will probably have to reload these drivers - get them from the manugacturer of the computer/mother board.
What ever happened was 97% not caused by the power supply replacement.
is there a post beep when the pc is switched on. check the memory if it is a beep beep beep sound , also disconect the hard drive, dvd drive, floppy, and any usb devices and see if it boots up. if that fails it does seem like the mother board, also check the cpu fan has it stoped. also find out the power switch conector on the mother board, from the base unit switch to the mother board. also chech the power connector from the power supply to the mother board , on newer boards there are two that go to the mother board its self , a big one and a very small one .
