Recently built an I3 Home theater PC using an MSI motherboard. I am also using a USB IR reciever from an off brand Media Center remote from Amazon to use with my Harmony remote. The issue is that I dont get any video over HDMI when the USB IR reciever is plugged in, the screen stays black. However if I plug it in after windows loads it works fine, I can even reboot and it still loads windows fine. The screen will not show any video if I do a cold boot. If I hook the PC up to my desktop monitor with either the DVI or d-sub and the IR reciever plug in, it loads windows fine fome a cold boot. Any ideas? I have ordered another brand IR reciever to try.
