Learn English – word for turning something into a competition

The situation you're describing doesn't so much sound like she was putting no thought into her answers, as that she didn't want to have the conversation, and therefore was deliberately not engaging with the conversation, perhaps to send you a signal to stop talking to her.

This style of conversation would be described as dismissive

If you want something as specific as "made worse while trying to fix it", you'll probably need to look into jargon and slang coined by people who have had to deal with managers who aren't as knowledgeable as they think they are. It's a common enough situation that such slang will probably be widely familiar.

That said, "messed up" (as suggested by James Wolpert) or synonyms and slang with the same meaning would be my next resort. Generally, with a computer, if there's no physical connotation inherent, people will assume a software-related meaning.

Something like "screwed up", "borked" [1] [2], "hosed", "botched up", or, if you want something that may be too specific, "reformatted".

There are probably more examples people will recognize lurking in The Jargon File (The slightly more updated online edition of The New Hacker's Dictionary) but I don't have time to go looking through it all.

Depending on the use, you could also try putting a word in sarcastic/mocking quotes, such as "reconfigured" or "fixed".
