Hello,
I recently bought new motherboard "Intel BLKDH77EB", everything seems working fine except graphics card "Nvidia GeForce GT 630" (GeForce GT 630 - Graphic solutions GeForce & Radeon). Problem - video card is not recognized by the BIOS or PCIe x16 slot, or PCIe slot doesn't work correctly in some way. Video card is connected and receiving power supply - at least video card fan spins, but no video signal comes out from any video card outputs: DVI: 1x Dual-Link DVI-I nor VGA. I tried to install Nvidia video card driver, but in installation process I got wizard message: no compatible video card found.
Also the video part (tab) in the BIOS shows info: PCIe x16 slot not populated while video card was inserted. Right now BIOS is as it was, no any updates except those which was in motherboard accompanying CD in package. Onboard integrated video works normally.
The video card worked normally in two another systems. Also I don't have any other (non Nvida) video card to test whether this PCIe slot works at all.
Information about my computer main units (they all are new and unused):
Motherboard: Intel BLKDH77EB
CPU: Intel BX80637I33220
RAM: Kingston KVR16N11S8/4
Power Supply: Xilence SPS-XP350
I hope for some solution, please let me know if You need any other information.
with best wishes.
