I recently built a machine with a Gigabyte GA-p55-UD2 motherboard, a Gigabyte 9600GT video card and a core i7-860 processor. When I tired to install Windows 7, the machine froze after the reboot where the video driver is installed. I could not install windows 7 at all. I tried Vista and that went well since Vista does not install a video driver during the installation. But after I installed the driver, the system froze. So I assumed the video card was bad and sent it to Gigabyte for repair. Meanwhile, I installed Windows 7 using an old video card.
Gigabyte said the card was fine and sent it back. I tied it again in the already installed OS and it failed. I then tried a Radeon card and it would work for a while and then blue screen. So I assumed now that it was a MB problem. (The memory checked out with Memtest.)
On a whim, I put the 9600GT card in the PCIe-X4 slot and lo and behold, the system ran fine and has been stable for two weeks running two 24" monitors. My question is, what am I losing by using the X4 slot instead of the X16 slot. I am not a gamer but got the card to support two monitors. If I replace the MB with one with a working X16 slot would I notice any difference? I just hate to send the board back and be without a computer for two weeks. Are there likely to be any other problems in the future with this board?
