Id10T error is a common term used by the IT helpdesk to describe an error on a users confuser.
After repeatedly attempting to help the user fix a confuser glitch, the IT personnel will give up in frustration and claim the error is an “Id 10 T” error and the user needs to contact Microsoft support.

<tech 2> Yea, this time his monitor screen was all black. I told him it was a Id10T error and he needs a new monitor.
