Hey guys, ive got a problem, i got a "new computer" from my aunt, i bought graphic card GTX 950 but every time i plug it in, it shows "please shut down and connect pcie power calbes(s)"(ive got a vga monitor+TV w/hdmi), when i looked at my device manager ive got a problem with pci simple communication controller, i have tried to get drivers/new bios, but unfortunately intel deleted all drivers for my mb, got d946gzis, so is there any solution for this?
