Ok guys, please help me with my problem. I just built a computer with the following specs:

CPU: AMD Phenom II X4 920
CPU Fan: Cooler Master 212 Plus
M/B: Asus M4N78 PRO, AMI [COLOR=blue !important][FONT=inherit !important][COLOR=blue !important][FONT=inherit !important]Bios[/FONT][/FONT][/COLOR][/COLOR]
GPU: Asus 560 Ti DCII 1Gb
PSU: Thermaltake 650W
RAM: 6 Gbs (3 x 2Gbs)
SSD: OCZ Vertex II 30Gb (System)

So I put everything together, press the power button, all the fans start spinning (GPU, CPU, [COLOR=blue !important][FONT=inherit !important][COLOR=blue !important][FONT=inherit !important]Case [/FONT][COLOR=blue !important][FONT=inherit !important]fans[/FONT][/COLOR][/FONT][/COLOR][/COLOR]), then I notice a strange thing: CPU fan stops spinning for about 6-7 seconds until I hear one beep, then it starts spinning again fast, then I hear two short beeps. There is no video, my monitor is blank and does not come on. I can't figure out what the problem is, I tried re-seating RAM, it did not help, tried re-seating the CPU and cooler, nothing changes, still getting 1 beep at start and then two short beeps. I figure it gets through POST but then what happens? I tired re-seating GPU, does not help. Can you help me determine what it can be? I just got this new M/B because one day when I turned on my computer the monitor / video did not come on nor did my computer give any beeps. So I tested all other hardware part on my friend's computer and everything worked so I though it had to be the M/B (I also found out that the M/B speaker died that's why I did not hear any beeps), so I replace the M/B. Now I don't even know if the reason was the M/B or something else.


Thanking you all in advance for all the help you can offer!

Check your motherboard manual for the beep codes but sounds like video issue.

Reseat the gfx, is there another pci-e to try? Make sure you haven't got the monitor plugged into the on board VGA ?

Or maybe remove the gfx and try onboard VGA if it is compatible?

I tried using the same GPU in my friend's computer. Works fine.

Tried using on-board GPU, the same results (2 beeps).

There is no beep codes in the M/B manual...
