Hello, I recently bought an Asus Radeon R7 240 GPU for my Conroe1333 DVI/H motherboard.

I'm experiencing a problem that my card doesn't give signal. I have setted my BIOS to PCI-E (I had a Radeon 2400 pro before) , and my PSU is 600W.

Is it compatible with this motherboard? I have uninstalled the onboard drive but nothing is happening. My BIOS version is 2.10

Does anybody has any idea what the problem might be?
