I suggest you take one step at a time and avoid making assumptions about what may or may not have been corrupted. Get the adaptor, and verify you get the computer displaying on the monitor. Then, if it boots properly, then all is well. If it doesn't, call the supplier and tell them it doesn't boot properly.
It's a new computer and all you've done is only what any reasonable person would do if they can't get a display on the monitor.
