Hi, I have 2 PCs each with different configuration: PC 1: Gigabyte motherboard Intel Pentium G3220 4 GB RAM PC 2: ASUS motherboard Intel Pentium G550 4 GB RAM I also have 2 GPUs: GT 610 and GT 630. The problem: GT 610 works on both PCs BUT GT 630 doesn't work on PC 2. On PC 1 the both GPUs run without problem. Info: no signal at the monitor either HDMI or VGA in PC 2. On PC 1 everything works with GT 630.
