I just did a new computer build with the DH77EB motherboard. Whenever I enter BIOS setup, I am having issues navigating the menues. When I first used it, it was acting as if my right arrow key was stuck. The menues were constantly scrolling through to the right making it very hard to select and change options. I updated the BIOS, and that issue has gone away for the most part, but when I press Enter to choose an item, it acts as if my ESC key is stuck. The menues I enter are almost immediately exited out of and takes usually 3 or more tries to keep the new menu on screen long enough to make my selection. I've also noticed the mouse cursor drifts to the right side of the screen. If I move the mouse, the cursor will then continue to drift in the last direction my mouse was moved. I have a Microsoft Wireless Keyboard 5000 and Mouse 4000 that use the same USB receiver, but I've never had any issues navigating BIOS setup with any other computer I've used with these input devices. Does anyone know why the BIOS setup screen would be behaving this way?
