My desktop died.
when I boot I get BEEEEEEEEEEEEEP- BEEP- BEPP One long, two short beeps. google search pointed to video card. I pulled it and the fan was burned to hell and gone. Ordered a new NVIDIA card and installed it. Still getting same post beep. cleared the CMOS battery and same trouble. I"m getting good voltage on my ATX and MOLEX plugs, under load, sticking the VOM leads into the back of the connector while its running the MB. also fans are going fine. monitor does not get signal. I'm thinking the old video card also fried the MotherBoard. Before I order a new MB, is there anything I'm overlooking/forgetting? Thanks MB = ASUS M2NPV-VM |

I had a similar problem about a month ago. I had thought I heard a certain sequence of beeps but I got it wrong. I used the diagnostic lights on the back of the machine (and the manual) to figure out it was a loose connection on the RAM.
About a day later, I got more beep codes, and turns out the video card had also unseated. After I reseated the RAM and video cards, everything was hunky dory. So, maybe take your RAM out and reseat it. Worth a shot. |

my guess is that whatever event killed your old video card killed the slot you're using. See if you have a spare PCI (or whatever) video card to pop into another slot and verify that it will at least POST without beeps; if this is the case, try the new card in another computer and verify it POSTs without beeps. Then you know it's the slot (or something on the mobo, which really amounts to the same thing).
eta: when you plug into the DVI port on the motherboard, does it POST? |

Here's something I would do.
Pull the video card out, and hook your monitor to the onboard video outlet on the back of the motherboard. It's possible when you pulled the CMOS battery, it reset the BIOS to default to onboard video. Kinda unlikely, but what do you have to lose? If you do that, and that doesn't work, I would consider RMAing the MB, or getting a new one. It's possible the overheated video card might have done some damage to your PCI-E x16 slot. |

Don't forget that pesky coin battery for the CMOS.  A machine will boot without a CMOS battery most of the time, but pulling the battery and letting it reset might clear up the problem. (most likely it's a hosed motherboard though..) Yank all daughter cards. Yank the ram. Pull the battery. Replace battery, replace ram. Try to boot. If she starts, replace cards one at a time until you hit your trouble. But I'd bet a boltface sticker you don't get past the "try to boot". On the upside, at least it wasn't the hard drive. Motherboards come and go, but data loss is what really hurts. |

On the motherboard there will be a fair number of electrolytic capacitors which are shaped like little beer cans, with plastic labels shrink-wrapped around them. The tops of these capacitors are usually bare aluminum and have an embossed K. X, or other similar design on
them which acts as a blow-off valve when pressure builds up the capacitor when it reaches the end of its life. If the top of the cap is not flat, or any goo is oozing out of it, it is definitely bad. Though the caps CAN be replaced, (and they should all be replaced if one is replaced), very few people will do it and it may cost more than the motherboard is worth. It might be better to get a replacement motherboard and be done with it. But be sure to salvage your existing memory and processor because they're probably still good. This might be a good time to upgrade. I recommend upgrading over buying a new PC because your Windows installation key will still be legally valid if you do a motherboard replacement in your existing PC chassis. CJ |

I've pulled everything off the MB, RAM, IDE/drives, video, everything, and still get the same POST beep. I also pulled the CMOS battery for a few DAYS and tried again. No change She's dead Jim 
When you get the new MB, add the components one at a time. If you've got one daughter board and a MB dead you might find more. With a good power supply it doesn't sound like a surge though, so that's good. |

Have you tried clearing your bios as well?

Well at least you're getting beeps.
My MB died but still powered on some components, but no beeps. Depending on the board, you may be able to find a cheap one at frys or over on hardforum.com frys does have some good deals, my last agp vid card was FREE (minus taxes) after rebate when I was diagnosing my old (now defunct) pc. Can you try vid from another slot? |

Think the fan died first and took the rest down from heat? The MB going in that case is kind of a surprise, but anything's possible. This is what I've been thinking. I've already bought an other Video card......before I spend more money on an MB, I thought I'd ask around. Now I need to find another MB with AM2, DDR2, 2 IDE, and hopefully firewire/1394 I've tried to find another M2NPV-VM, but so far, I can't locate one. Maybe this one http://3btech.net/asm2soammowi.html and a PCI firewire card. (I need firewire for my sony video camera) Thanks to all for your help. |
