Help Please! What Happened To My Mobo?

[Dan]

Rather than hijack FiberOptik?s thread, I thought it better to start this one.

When I turned on my system this morning (A7N8X deluxe mobo/Athlon 2500+/2x512MB Kingston HyperX PC3500) it wouldn't boot up. Fans spin, LED's light up, etc. but no beeps. I powered down normally last night and everything was fine so I was at a loss to figure out what happened.

My first resoponse was to unplug the power, remove the CMOS battery and set the jumper to clear the CMOS.

After work today I reset everything but there was no change. Clearing the CMOS didn't help. A different video card didn't change things either. At this point the drives are unplugged, the video card and RAM removed and yet still no change: the mobo gets juice but won't boot.

Two other things:

1. While removing the replacement video card, the board got a shot of electricity. (A discharge?) By that I mean, the LED case fans & cpu fan suddenly lit up and spun for a second. The PC was unplugged when it happened!

2. All of the capacitors on the board look okay to me.

You need RAM and video card to boot. How did your PSU voltages look when you were running? Could it have fried the board? Had you flashed the BIOS or played with any setting just before your last boot? That is pretty strange about the fans spinning up, I dont think static discharge could do that. THat makes me think something is odd with the PSU though.

I would try a different power supply next, as its easy to swap. Usually a bad video card or RAM will give you beep codes. If the PSU is good you might look hard at the motherboard or CPU. A POST card might help, but I doubt that it will from your description.

Good luck Dan.

The odd thing is that I hadn't changed any settings, bios, etc. The power supply (450 Watts) is less than a year old. Nonetheless, I'll try another new one that I have on hand.

In the meantime, I sent an e-mail to ASUS' tech support. (I haven't received a response yet.) I'm also picking up an Abit NF7-S at mwave after work this morning.
