Hello
Please help me with this odd problem with my new motherboard!
The motherboard just wont post past the bios splash screen and just freezes there, i cant even go to the BIOS!
But the motherboard will boot to windows when i use the onboard graphics.
These are my specs.
Phenom x4 955 black edition (NOT OVERCLOCKED)
7GB DDR2 800 MHZ NON-ECC
Coolermaster hyper 212 plus cpu fan.
500GB HDD
500W powersupply.
GTX 660 OEM 3GB GDDR5.
GA MA785GM US2H REV 1.0 Motherboard

This is what i did for troubleshooting:
Checked GPU to my old motherboard and it just works flawless and boots to windows so the GPU is working perfectly.

Attached all the cables and powercables to the motherboard and the GPU and they are all attached properly!

Removed the CMOS BATTERY but still dodnt work.

Set the start up bios settings to PEG that means to PCI-EXPRESS graphics.

I am really confused what is going on with my new motherboard.
I´ve also added a photo but this is not mine! It has similiar screen as mine when i boot up with a graphics card.http://
PLEASE HELP ME!!
Regards
