NF4 SLI-DR won't post - 3 leds and flashing power or 2 leds and nothin

[Spanky Deluxe]

My system's been running fine for months. Last night it suddenly stopped working, I powered if off and it wouldn't come back on again.

 

The diagnostic LEDs showed 2 on - i.e. just before its trying to connect to the graphics cards.

 

I thought initially that it might be a problem with the power supply. I've tried another one and everything is still the same.

 

When I take out the graphics card from the lower slot the diagnostic shows up a different arrangement - 3 LEDs on and the power led keeps flashing wildly at the front. I've tried every combination of the two cards in the two slots. If there's a graphics card in the lower slot then 2 LEDs, if there isn't then 3 LEDs.

 

I've tried clearing the BIOS, taking out the battery, leaving it for first 10 minutes and then about an hour (I forgot to do it again overnight - d'oh!).

 

Does anyone have any idea on what I should do? I'm going to try to dig out an old PCI graphics card (non express) to see if it'll boot with that. I think something may have gone funky with the PCI-Express bus.

 

My specs are the following:

 

NF4 SLI-DR

AMD 3700+ San Diego cooled by a single phase change, normally running at 3Ghz

Crucial PC2700 memory (yes I know, slow - I ordered some PC4800 about 6 months ago and it got lost in the post, I can't afford anything more right now!)

2 x Gigabyte 6800 GTs.

Thermaltake 550W PSU.

Loads of Hard drives and two optical drives.

 

What can I do?!!

 

 

Edit: I've just tried a PCI graphics card and I get the same 2 LEDs as before. I don't have any other PCIe graphics cards to test with, nor do I have any other motherboards in which to test the cpu etc.

 

Edit 2: If there aren't any cards whatsoever in the system then I get 2 LEDs as well. I'm going to try switching the SLI configuration jumpers and see what happens then.

You can use my sig as an example.

 

You should never get the front panel power LED flashing unless you'be entered the OS's Hibernation or Standby mode

When the board was set to non-SLI mode, 2 leds came on when a graphics card was plugged into the top board.

 

ExRoadie, I've updated (well created) my signature like you recomended. I'm following those steps in the second link now. I'm going to try a 15 minute clear and if that doesn't work then I'll just have to leave it for longer.

 

Thanks for your help by the way!

[Spanky Deluxe]

Well the 15 minute clear didn't help - still 2 LEDs.

 

Guess its gonna be an 8 hour clear now.

[Spanky Deluxe]

I've just tried starting her up after a 15 hour clear... no change. I still get the 2 LED error. What should I do now? Can I get a new bios or should I RMA? I'm based in the UK btw.

[Spanky Deluxe]

I still get absolutely nothing. What can I do now? Is this an RMA job now or do I have to get a bios swap or something?

Hello Spanky, did you ever solve this problem ?
