Why does the power to my bedroom keep going out?

The breaker that leads to my room goes out randomly. Not often, but at least once a month everything will shut down. I can fix it by flipping the breaker, but I’m worried it’s a deeper problem.

I originally thought it was because I had a lot of electronics running and too many things plugged into one outlet, but after moving things around it still happens, even if the only things I have on are my alarm clock and desk lamp.

What should I look for that might be causing this? Is there anything I can do to possibly fix this myself before calling an electrician?
