Beer Moon Posted July 14, 2005 Posted July 14, 2005 I just received a brand new NEO 480 PSU to run my LAN Party ULTRA D and it won't budge. The NEO 480 powers my s754 box (that I'm posting this with) perfectly. I have the CPU and Zalman 7000 ONLY plugged into the board right now, looking for a POST or any signs of life whatsoever. I had everything plugged in but it did exactly the same thing. Need help figuring out this board which for all intents and purposes seems to be DOA. ONLY the Standby power LED goes on, not the LED by the RAM slots on the mobo. I do not have the breakout box with additional LEDs. When I hit the reset or power buttons, absolutely nothing happens. Not a peep, not a spin of my CPU fan, nothing. I have tried the 10 minute CMOS clear, and I am getting exactly teh same results. The board won't POST. Any suggestions?

StephenC Posted July 14, 2005 Posted July 14, 2005 Beer, use this as a guide to double check your build. Also take a look at post 95 in this thread. http://www.dfi-street.com/forum/showthread.php?t=6615 Also my want to try with your motherboard outside the case.

Beer Moon Posted July 15, 2005 Posted July 15, 2005 Thanks for the tips. Here's where I'm at: It's already out of the case. There is no difference in the board's behavior though. Whether it had a stick of RAM in it, a SATA drive connected, nothing changed it. It just sits there with the Standby light turned on. I regressed to the most basic troubleshooting, so I won't be using the guide to plug in 1000 things. It's a brand new PSU and CPU. Unfortunately, I cannot swap out the chip, but it LOOKS fine. Anyway, there's a POST beep code for bad CPU, and as I said the mobo will not POST to even tell me that much. There is no RAM, only the CPU, HSF with the fan plugged into the CPU Fan, and all four power connectors. I changed the Audio jumper to ON, so that it should spin up the fans on the NB and my CPU, and then beep at me because no RAM is detected. No luck.

Beer Moon Posted July 15, 2005 Posted July 15, 2005 Oh and as for post #95 on that thread, I'm already way past troubleshooting this board in the case. It won't go in the case or get a hard drive connected till it starts POSTing. I will redo the CMOS reset, although 10 minutes is certainly the longest I have ever heard of for requiring a CMOS reset. Just FYI I have already done it with a good 20 minutes, and the battery removed for good measure. Quote Share this post Link to post Share on other sites More sharing options...
Beer Moon Posted July 15, 2005 Posted July 15, 2005 I can see the manual says the board has 2 LEDs. One by the bottom PCI slot, and one by the RAM. I can see both, but only the one at the bottom of the board by the PCI slot lights up. When the board is on standby power with an active PSU connected, do you usually see one or two lights before you power on the board?

StephenC Posted July 15, 2005 Posted July 15, 2005 With power off, you should only have the stand by led below the bottom pci slot lit. The ram led lights up when you power up your system. As well the 4 red diag led's near the standby led. Do they come on at all? Here is how you would read the diag. led's 4 LEDs on = Power applied 3 LEDs on = CPU has been detected OK 2 LEDs on = RAM has been detected OK 1 LED on = VGA has been detected OK 0 LEDs on = System has booted to the Operating System. Do you have access to another processor.... Quote Share this post Link to post Share on other sites More sharing options...
Beer Moon Posted July 15, 2005 Posted July 15, 2005 Lol I knew that was the next question. OK the four diagnostic and RAM LED have never, ever come on since I have had the board out of the box. Just that trusty stanby LED. At least something on it works eh? Thx for that info too. As far as another 939 CPU: No. It was brand new retail out of the box though. So was the board for that matter, but... At this point I don't suspect the CPU since the board isn't willing to power up in the slightest or even begin the POST. I have had CPU's "go bad"/killed them before, and I was always able to get the board to POST and start beeping at me that the CPU was bad. For that reason, I am highly suspect of the board at this point, and not the CPU. Willing to try whatever before I begin the (probably inevitable given my luck) RMA though. I hope Newegg will cross-ship, because I am getting antsy. Thanks again for your suggestions. Quote Share this post Link to post Share on other sites More sharing options...
StephenC Posted July 15, 2005 Posted July 15, 2005 Just curious, have you tried shorting the two power switch connector pins on the motherboard with a small screwdriver, to see if it would power up? Quote Share this post Link to post Share on other sites More sharing options...
Beer Moon Posted July 15, 2005 Posted July 15, 2005 No luck shorting them. Quote Share this post Link to post Share on other sites More sharing options...
radd Posted July 15, 2005 Posted July 15, 2005 Have you tried adding a video card? Quote Share this post Link to post Share on other sites More sharing options...
Beer Moon Posted July 15, 2005 Posted July 15, 2005 No change with vid card plugged in either. Any other suggestions? Quote Share this post Link to post Share on other sites More sharing options...
Beer Moon Posted July 15, 2005 Posted July 15, 2005 Any advice from mods? I am thinking RMA time at this point. I really hope Newegg will cross-ship. Quote Share this post Link to post Share on other sites More sharing options...
