FBI report only contains criminal charges, arrest warrants or info related to crimes commited while in the US. Opening a bank account, buying cars, obtaining credit cards in the US are not crimes, thus it will never show on you FBI report.
Overstaying your visa won't show either unless (as future_canadian says) you were arrested, or appeared before a immigration court or a warrant for your arrest has been issued. If you left out of your own accord, you are in the clear.
From the FBI website, this is what shows on you report.
An Identity History Summary—often referred to as a criminal history record or a “rap sheet”—is a listing of certain information taken from fingerprint submissions retained by the FBI in connection with arrests and, in some instances, federal employment, naturalization, or military service.
If the fingerprints are related to an arrest, the Identity History Summary includes name of the agency that submitted the fingerprints to the FBI, the date of the arrest, the arrest charge, and the disposition of the arrest, if known to the FBI. All arrest data included in an Identity History Summary is obtained from fingerprint submissions, disposition reports, and other information submitted by agencies having criminal justice responsibilities.
