Hi All,

I recently put together a new PC with following spec.

CPU: Athlon 64 X2 3600+
RAM: Corsair XMS2 6400 DDR2-800 2GB
Graphics Card: Gigabyte 7600 GS 512MB (GV-NX76G512P-RH)
Motherboard: Gigabyte GA-M57SLI-S4 (Rev 1.1) BIOS F5

When I plug the graphics card into the first PCI-E slot, the PC powered up with a blank screen and followed by 1 long and 2 short beeps.

I tried to insert the graphics card into the 2nd PCI-E slot and it works perfectly in x8 mode as shown in nVidia control center.

At first I thought it must be a faulty motherboard, and to make sure, I borrowed an ATI x1800 from work to test it out.

However, it turns out the ATI card worked fine in first PCI-E slot so I thought it must be the graphics card problem then.

I return the graphics card to the computer shop but when they test it on a Asus P5ND2 SLI board and it worked fine...

Now I'm really confused, anyone got any idea on why this is happening?

I send this question Gigabyte support about a weeks ago using their online support form, however they haven't even read my question yet ...

Hi,

actually in the manual, Gigabyte recommand people to put graphics card in first PCI-E slot so its certainly not the case with this motherboard.
