For the record, I’m a designer, not an IT guy. However, some clients still try to hit me up for tech support

Client: There is a weird noise coming from my computer.

Me: Can you hold your phone up to the computer so I can hear it?

Holds up phone, hears mechanical rattling in the computer.’

Me: Sounds like there is something stuck in the fan. Have you stuck something in there?

Client: Yes - a nail. I wanted to get the dust out.

Me: And you left the nail in there?

Client: Yes - can you get it out? You figured out it was in there, could you get it out for me?

Me: Not without being physically near the computer. 

Client: But you figured it out over the phone! Why can’t you do the same thing with fixing it?
