This is a recurring problem I have been having. The light on the front of the PC, the one that should be solid when the computer is on is blinking. When I posted on this in the past, there was a suggestion that perhaps this meant the hard drive was kicking out. Furthermore, at times the HD in question was making some strange noises(I believe clicking). Therefore, i got a new HD. I believe the blinking stopped for awhile after this. Regardless, the blinking is back, along with my frustration. I had had the old drive in as a slave, but i just unplugged it and I still have blinking. Specs are as follows:

Athlon xp barton 2500+ (not mobile)
Xfx Geforce 6800 nu w/ zalman vf700 cu @ 400/770
Asus A7n8x deluxe
Antec Neo Power 480 W
1.5 gig ram - 1 gig stick ocz platinum and 512 stick kingmax
 
hdd spin down? check power saving options in windows and/or bios.
 
Boot up with no IDE cables connected and see what happens.

Does it appear to be beeping out a code or pattern? Or is it a completely random flashing?
 
So does the light come on solid and then start blinking after a while or does it always blink?

Are there any other symptoms (Computer being off, not responding, etc...)?

Assuming you meant unplug the hard drives(which happen to be SATA), no dice. The flashing happens as soon as I turn it on. As far as beeping is concerned, none that im aware of. The flashing alternates every second. The light is never solid. There are no other symptoms that I am aware of either. I've thought of just unplugging the damn thing, but i figure that its flashing for a reason...
 
Have you tired contacting Asus?

I have the Premium version of that board, and built several systems using your version, and none of them have the flashing LED syndrome.

Do us all a favor and post back when you have a definitive answer.
 
It's a bug with certain A7N8X revisions, BIOS versions, and power supplies. It's totally harmless and is basically a bug which causes the motherboard to flash the power LED and indicate that the PC is in suspend-to-ram mode when it actually isn't.

You can fix it (at least temporarily) by doing this:

1. Shut down your PC normally.
2. Remove the power cord from the back of your PC (the PSU) OR flip the main power switch on the PSU if it has one.
3. Push the power switch on front of the PC a few times to fully discharge the power supply and motherboard.
4. Plug in the power cord, ensure the main PSU switch is on, and press the power button on your PC.

That should fix it until the motherboard decides to twitch again.

If that doesn't work you can clear your CMOS ram by using the jumper located near the battery on the motherboard. THIS should work 100% but be aware that you'll have to reset all of your BIOS preferences again since they will reset to defaults.


Some people report that the newest A7N8X BIOS solved this issue for them so you might want to make sure you are running that version and if you're not try flashing it.
 
if it is blinking randomly and fast it could just be that it was not connected properly (connected to HDD pins instead of power)
 
I dont know if swearing is is looked down on on the forums, and if so, I appologize but:
Hot damn! I turned it off and switched off the power supply and it did the trick. Time to check for new bios... Thanks!
