Computer problems?

I was having trouble with my computer. So I called Paul, the 11 year old next door, whose bedroom looks like Mission Control and asked him to come over. Paul clicked a couple of buttons and solved the problem.

As he was walking away, I called after him, ‘So, what was wrong?  He replied, ‘It was an ID ten T error.’

I didn’t want to appear stupid, but nonetheless inquired, ‘An, ID ten T error? What’s that? In case I need to fix it again.’

Paul grinned…. ‘Haven’t you ever heard of an ID ten T error before? ‘No,’ I replied.  ‘Write it down,’ he said, ‘and I think you’ll figure it out.’

So I wrote down: I D 1 0 T

I used to like Paul,  the little bastard.
