I have a GIGABYTE GA-965P-S3 Socket T (LGA 775) Intel P965 Express ATX Intel Motherboard. I have, however, figured out the "no monitor signal" problem. I had the motherboard seated a bit askew, and when I screwed the card into the case it stretched it, and pulled some pins out. I re-attached the motherboard and put the gfx card back in, and it turned on. A stupid mistake on my part
I now have another problem. The hard drive that I have plugged in is not being recognized. I know it's getting power because it spins a bit on startup, and I have it plugged into the SATAII 0 port on the motherboard.
