I have recently rebuilt some old components into a pc under water. Spec is as follows:

Asus A8N SLI Deluxe (Skt 939) (Under Water)
AMD 64 X2 4400 (Under Water)
2x Corsair 1GB DDR500, 2x Corsair 512MB DDR400
Corsair HX620
AMD 5870 (Underwater)

The last time I used the CPU, MB, RAM was end of 2008. it has been sat in an old case ever since.

When i power the PC up, fans spins, an led on the motherboard turns on and is green, waterpump starts etc. No display, no BIOS beeps etc. This board supports audio bios fault description thing, a voice says whats wrong. This isnt working. I know I have found before that I had to have the FP audio connected for the rear to work. I connected my fp audio but its very hard to get the connectors in as they are not in a block. This still didnt work.

Things I have tried:

  • Resetting bios via jumper & removing CMOS battery
  • Changing CMOS battery (one that was in there had been there for ages, replaced with one from another pc that has had approx 1 month total use)
  • Checking PCI E power, 24 and 4 pin connectors
  • Using both a 4pin and an 8pin MB connector
  • Reseating CPU
  • Using an old pci e card in primary slot and secondary slot
  • Tried 2 different sticks of ram on their own in 2 different slots
  • Tried no RAM
  • Disconnected FP Firewire, Audio & USB
  • Tried plugging an onboard speaker into the connector on the board, no beeps

The PSU was working fine in my pc in my sig in August when I replaced it. The graphics card may not work, but I have no reason to believe it doesnt. An old card didnt work either. I dont think its a case of something shorting as it doesnt turn off and will start every time.

I think next step is to dismantle the whole thing, build it outside a case and stick another cpu in with an aircooler and maybe another working gpu. Trying to avoid it as its rather a mammoth task due to wc loop (CPU, Chipset, GPU, Pump, Res, 2x Rads).

Any last suggestions? I'm thinking likely a board failure.

You've done quite a bit of exploratory work already and to be honest I'm not sure you've missed much. You don't mention any fault beep codes so I'll assume there isn't any. Have you tried booting without the CPU? If you don't get any fault beeps from the motherboard speaker I think you can point the finger of blame at the motherboard.

Other than that the only other thing I can see is checking cable from the graphics card to the monitor.

If nothing works I think you'll have to bite the bullet and rebuild outside of the case on air.

No beep codes at all, but i think its mainly geared towards audio from the rear panel on this board. I think thats half the problem having no beep codes.

I have tried DVI / HDMI to my 24" and VGA via DVI adaptor to my 19" so its deffo not that.
 
how long did you leave the battery out for? i build an old system that had been sat in a box for 4-5years and found i hadn't left the battery out long enough when i first tried it.

Leave it out for about 30 minutes and try again.

I previously left it out for 10 - 15 minutes.

Left it out tonight for 1 - 2 hrs no effect. Guess it will be a dismantle at the weekend.
