Black Screen on Boot with Amd M3A32-MVP Deluxe

Hello,

I assembled my new system:
Asus M3A32-MVP Deluxe
AMD X2 6400 + black edition
Leadtek WinFast px8800gt
2x Corsair DDR2 800MHz TWIN2X (ie 4GB)
Description Corsair HX520W power supply

I've done and everything went great. CPU with a maximum of 45 ° C.
I still do not overclock or other extraordinary things done.
However, the monitor has black with no beepcodes

after I've reset the bios, it works now irregular and rare (about 1 times in 15 attempts) that I see great Asus logo.
either remain there or hang then nothing happens, only the tip of the red BIOS logo, the rest is black.

I have the graphics card in my old system times tested and it works just fine.
RAM and CPU, I can not replace my old board since none of the two supports.

What to do ??

I have some times problem with A7N8X-Deluxe.

Still doubts about this error:
It is sufficient if you are not 100% compatible RAM used (only with this manufacturer is experiencing), so it never starts. If you are lucky it can run up high Winbugs may work. While Playing, suddenly the box is dead if you're unlucky then across the board.

The fans are running nothing else?

Then this could be the reason:
The CPU receives no electricity, so the monitor stays black.

It seems to be a driver problem. If you don't install the drivers, it will work fine. It's more than likely that it is enforcing a mode not supported by these monitors. My old monitor, the FPD1760, doesn't support the protection over DVI. Also, I noticed that it may be trying to read the EDID incorrectly. I used powerstrip, and it showed my monitor as a 85hz capable monitor, when it is only capable of 75 max.

1) Reset ALL connections monitor, computer, RAM, Video Card. Have the main power to the wall disconnected first and ground yourself, if you're prone to static discharge like I am.

2) Try a different monitor

3) Remove some of the daughter boards (sound card, modem, raid card, scsi card, extra NIC...) I've seen overloading of the North Bridge, giving problems.

4) Removing all the daughter cards can help if the PSU is weakening, it could have failed completely, if not catastrophically. It may not have enough power to run the whole computer, but maybe a minimal system.

5) If it starts with only video card, start adding cards till the system breaks again.

6) If you get it to start with a minimal system, run MemTest, to test your RAM. I have one at work now that has some weird stuff happening, but I've tied it to RAM, even though it reads to be a Motherboard.

What all tests have you performed?
