Question about EliteGroup ECS MB N2U400-A NFORCE2 ULTRA400 SocketA FSB400MHz 3DDR 1AGP8X 5PCI ATA133 (NEWITEM22594383) Motherboard

2 Answers

I was adjusting the BIOS settings of my N2U400-A motherboard when I accidentally turned on the computer with the "reset CMOS" shorting pin in the wrong position. This resulted in my computer only displaying a blank screen, and I can't reset anything now in order to access the BIOS setup program. I think I may have completely erased the BIOS chip, and want to know if there is any way to replace the "Award BIOS" on the chip. Can I use another computer to copy the BIOS program that came with the N2U400-A onto a floppy disk, and then have the floppy plugged in when I start up the computer? Send any ideas or suggestions to

Try removing the power from the back of the computer. Then remove the clock battery that's located on the motherboard. let it sit for about 20 seconds, then plug everything back in a give it a try.

The bios in this system is not fully acpi compliant

It's possible that the BIOS setup has been accidentally set to non ACPI mode. Check in the setup to ensure ACPI is enabled.

Other possible causes that have been pointed out are memory expansion, overclocking and incompatible driver software. Check out what you have recently installed or updated on your computer

removed RAM from one slot and boot
or check the bios update
good day and rate solution if it helps

How do I reset the cmos settings for the msi motherboard ms 6570?

If you're unable to enter your BIOS, or if you set a system password in the BIOS but forgot it, you might be able to fix the problem by clearing the CMOS memory. On some motherboards, this requires you to turn off and unplug your PC, disconnect the CMOS battery for a few hours, replace the battery, and turn on your PC again. Other motherboards have a CMOS clear jumper pin that you must move to a temporary position and then return it to its original position.

Post back if you still need more help.

Thank you

Sound driver installation

Assuming you got them from the link below, there are 2 bios versions, you may have the wrong, one, or your sound chip is damaged, if so either you will have to purchase a pci sound card or a new board.

There is normally a system tamper reset within the bios settings somewhere. Alternatively try to reset by the JBAT1 terminal by putting jumper from pins 1-2 to pins 2-3 then back again and restart pc. You will have to set the time again and make sure the HDD is detected in standard bios settings and re start.
