Hi R..

That one uses the GeForce 8200 MCP...  The M3N78-CM is a similar board...

If you won't find one, look for a Micro-ATX motherboard: 24.4 cm (9.6 inches) x 24.4 cm (9.6 inches) that supports your CPU (find out what is your processor). You will probably need to buy new RAMs, compatible with your new mobo and supported by your processor. But before that make sure that your processor works. By the way, how do you know your motherboard is "broken"?

The computer stopped booting-up. I couldn´t go setup. At the blue screen I have these options: F10 = Setup Esc = Boot Menu F11 = System Recovery F9 = Diagnostics F10, Esc, F11, F9 doesn`t work. I unpluged the power and serial cable going to the hard drive and DVD,, I was able to get into the BIOS. I put new hard drive Seagate 7200.12 and I am not able to go Setup F10. I tried to clear the CMOS.

Hi R, I don't think your motherboard is broken. "I tried to clear CMOS" and? What happend? How did you try to clear it? Try this: 1. If you have a USB mouse, unplug it and see if you still can't access BIOS with the DRW and HDD connected. 2. If not, power off, disconnect HDD and DRW, power on, enter BIOS, set your DRW as the 1st device to boot from, save, quit BIOS, power off. Connect the DRW and the HDD (connect and disconnect devices only when the computer is powered off). Insert a Windows DVD in the DRW and power on. See if you can reinstall WIndows. If not, borrow a HDD from a friend and see if you can boot from. Could be also a bad power supply unit. Usually, you test all the components before deciding that you need to replace the motherboard.
