Will had a customer this week with a problem that he's never seen before, so he wants to share in hopes that it will help some of you if you ever have the same issue.
When the customer booted up the computer, they just got a splash screen; no boot up menu or anything and it didn’t boot into windows. Digging back into the far recesses of my brain, I recall that the first thing computers check when they boot up is hardware (keyboard, mouse, etc.) We unplugged all of the USB devices and then started adding them back one by one until we found out the problem. In this case, it was the touch screen. Touchscreens use either a USB port or serial port to allow the computer to communicate with the touchscreen. I got the screen replaced under warranty and in the meantime, the customer is using the computer with no touch.
It was a pretty easy fix and the customer was back up within an hour.
