8600GT no display error beeps

[oakman]

I've been looking around this and several other forums on the net to find an solution for my problem, but nothing!

So i'm trying to post a thread to see if someone can help me.

I have recently bought a ASUS EN86GT Silent 512mb DDR3 graphics PCI-E card for my computer.
The problem is when I turn the power on I get no display and one long and three short beeps.
I have been looking around for some error beep codes on my ASUS P4V800D-X mobo, think the BIOS is AMI.
The only solution I've come up with is rearranging my RAM sticks. This didn't help.
I have also updated my BIOS to update0704 and updated the drivers for the graphics card.
The strange thing is that this problem only appears when the computer is "cold". When i reboot several times it starts up nice and everything is working. I can even reboot from windows and it is no problem.
I have tried my old ATI 128mb card and it works fine.

Please help me!

Comp specs:
MOBO: ASUS P4V800D-X
PSU: 580W
RAM 1280MB Kingston PC3200
CPU Intel Celeron 2.53mHz

(GPU temp never over 55c celsius)

I've tried two different PSU:s, same problem on both.

I vote PSU. What was the specs of the second one you tried. How many volts do they have on the 12v rail.

PSU or MB caps

The other one was a 350w but I recon it wasn't enough.

I just went nuts with the multimeter, here is the results on my Apevia ATX-AS520W (sorry, I was wrong in my first post)

Specs:
DC output
+3.3V 28A
+5V 30A
+12 V1 16A
+12 V2 18A
-5V 0.3A
-12V 0.8A
+5VSB 2.0A

+3.3V +5V = 200W
+3.3V +5V 12V = 500W
Peak output 520W

MM rail test:
12v
POST: 11.96
Boot 11.99
Windows startup: 12.06
System at idle: 12.10
System at load: 12.02
Shut down: 12.07

5v
POST: 5.18
Boot 5.16
Windows startup: 5.17
System at idle: 5.17
System at load: 5.17
Shut down: 5.16

3.3V
Never changed from 3.43

All of above stated MM test results are median values. 12v went constant +/-1v
