Very slow POST and BIOS setup
« on: 13-June-07, 13:23:26 »


I've built a system around the K9N SLI Platinum and have a strange problem.
The POST is VERY slow and likewize is the BIOS setup VERY slow. Though, when the windows bootup logo is displayed the computer seems running as it should, as far as I can see. From power up to the windows logo show takes maybe 10 minutes, then windows boots in a few seconds. And windows seems to be running as it should.
When entering the BIOS setup it can take minutes from a key stroke until the actual menu choice is altered.

At startup there are a few beeps. From what I have found in this forum they are related tu USB devices, but it seems a little strange since the amount of beep doesn't seem to change if I unplug the devices. Anyway the beeps are as follow:


Where L is a low pitched beep, H is a high pitched one and P is a pause.

My setup:
K9N SLI Platinum, with BIOS rev. 1.7 (I have upgraded from 1.2, which the board had when I got it)
AMD Athlon 64 X2 6000+
Corsair XMS2-6400 TWIN2x2048-6400C4 (2GB in total)
Gigabyte 8600GTS (GV-NX86S256H)
Antec Neopower 480W
Western Ditital Raptor 74GB (WD740ADFD)

Does anyone have a clue on what the trouble can be?

I might add that you can see the text on the screen update. It's not like it's just there, you can see it build up an line here, a few characters there, and then maybe a few lines etc etc.

  • check CPU cooling system, ensure CPU FAN is spinning. check BIOS settings as well for low FAN RPM alarm alert.

  • Disconnect ALL USB devices and try what happens at startup then. (If you have usb-keyboard/mouse, disconnect these as well).
    If that doesn't change anything, disconnect your raptors and try again.
    ... next with only one dimm installed.

    I tried dissconnect all USB devices, and that seem to have done the trick. I then installed one after the other and have come to the conclusion that it's one of my USB hubs that, for some reason, is causing this. Very strange, to me at least. I never could have dreamt of that a USB device could cause something like that. I would have guessed on something with the graphics card or something... :-)
    Seems like I have to buy a new USB hub and toss this one in the garbage.

    Thanks for your suggestions, both of you!

  • What are the amps on the label of the PSU?
    As I can't find any specs on the Antec website for that PSU.
    Those beeps can also be PSU related.
    Or you have case-switch detection enabled in the BIOS (if it has that function)

    Can you play games without crashing?
    If not, it could be well the PSU.
