Hey all! MissusNesbitt here, but don't let the name fool you. It all started when I nuked the os on my parents' computer with a virus from a torrented album and I'm working IT full time for a non-profit now. I'm just a dude who loves taking things apart and fixing them. Throw in a healthy dose of tinkering and you've got the high level overview of the last 20 years of my life.
In addition to the IT passion and work I also sing opera, which keeps me sane when my users do their best to drive me to drink.
Hoping to up my repair game via participation in this community, as I've repaired a handful of motherboards over the years but never had the proper tools to do much more than guess.Comment

HI all,
Freshly joined. I hold an electrical engineering from Italy, but never put it to work. I prefer to repair and play with electronics. Found this site by searching for answers in one of my projects and joined. Thanks in advance for the help I can get (and probably need) in the future.Comment
