What does it mean when the red alarm lite is flashing?

As for the red light on the motherboard, thats just there to let you know that the power cord is plugged in and the PSU switch is ON. (It is in the manual somewhere, just in small type)

When you press the power button, does anything happen? Do the fans spin for a second then stop? Do you get any POST codes? Have you tried with the board out of the case and only the video card/RAM/CPU plugged in?

Unless you are hearing beeps from the PC-speaker there should be no real danger i recon.

Refer to this guide if you are hearing beeps and take the nesessary measures:

Good luck!

Loud beeping sound on start up , now will not start up , power ok

First remove the Ram and boot the system without it. If you hear continuous two beeps, then the problem is with the Ram, you need to replace it. If nothing happens, then your cpu or your motherboard is gone. Good luck. Thanks for using FixYa.

Won't post, no beep. No display on monitor. Tried different AGP video card, different memory. I have unplugged everything but the AGP card and hard drive. The monitor works on a different computer so...

Basically, display card, RAM and processor are the ones affecting the display. IF trying different memory and video card doesnot help. Try changing the different processor. Thanx with regards Sajan

No Post No Beeps just lights and fans

If the computer just turns lights and fans thats because you have a piece of hardware that is unable to start.

My guess is that you burnt one of the three:

The Board
A Card attached.

Disconnect the hard disks and DVD CD drives
Try removing a ram slot at a time and keep trying, keep doing that for all the pieces until you have none.

If at the end (when you get to a part where you only have Board and VGA plugged the computer still doesn't boot up, the best sollution is to try these 3 on another pc to make sure they are faulty before sending them to vendor.

Good luck

A7N8X-E Deluxe Nforce2 will not POST

I had the same issue a while back. You need to reinstall windows on the new PC. Your motherboard is expecting to see a certain hard drive that has the windows boot sector on it. If it doesn't see that exact hard drive the computer will never boot... so quick fix, just reinstall windows and everything should work fine.

DFI Infinity NF4 SLI won't start

Hi steve, PC repair is trial & error. I suggest you replace the power supply or test the power supply in another PC that also uses 4 SATA drives & two PCI-E slots for starters. Two boards with the same problem is odd. You must have the CPU & fan connected, memory installed, ATA 24_pin main power plugg connected (Page 17 in manual). 4-pin_12v power connected which is located (Just to the left of DDR1 memory slot). Looking at you're board the power supply should be no less than 500w.
CPU must have thermal grease between CPU & heat sink.
Even though you have fans running & LED's on & flashing, the power supply seems to be the first item to check. Make sure the bottom of the motherboard is not touching the PC case.
Try the above & post you're finding here.

Good Luck!

POST issues

Hello please take the motherboard back to place of purchase. This sounds like a bad board. I have had about 13 of the same board customers would call me on. there is a hairline crack somewhere on the board.
