Ebony, you have the computer in front of you and you don’t know what to check, how do you expect someone who can’t see your system answer that for you?
Figure out what antivirus software you have on it and search the web for how to find it’s logs. Determine what operating system you are running and search the web for security settings it has effecting USB drives.
Or take the computer to a local tech service and have them figure it out.
