ECS Nforce3 A Powers down

I have an ECS Nforce3 A motherboard that will power my system down when performing various operations. If I attempt to run a Disk Cleanup on my C:\ it will power down. If I attempt to install Windows XP on a brand new SATA HDD from the Windows XP CD it powers down in the middle of the process. I am pretty sure it has something to do with the BIOS but I am at a loss. Any ideas?

Re: ECS Nforce3 A Powers down

Doubt its the bios. Did you install the sata drivers during boot? When u say it powers down does it just switch off or blue screen first?

No Lan appears

  1. Chek out in your BIOS that the LAN is enabled or not, if there is option it must be enabled.
  2. First install your chipset driver then your on board LAN will be avail for windows. After that you can install the LAN drive
  3. Might be the driver is not for your chipset, so also varify that you have proper driver for your device and Operating system.

If any more question...just Ask me

hi, see if you have installed any new devices/hardware to see if its conflicting, often grafics cards conflict usb devices, also just check that in the setup(when you boot up)that the usb ports have not been disabled or usb keyboard support hasn't been enabled/disabled. good luck!!

Powers on but no video.

Your motherboards RAM is not working properly. First you try getting it out and installing again. If that not work you can change with other one.
