We noticed several status messages during the flight: Flap/Slat control 1; Flap/Slat position sensors and a few others. We contacted Tech [OPS] and discussed. Decision was made to continue and possible options. As we approached ZZZ we were cleared the Arrival; Visual XXR and cleared to descend to FL 240. As we approached T/D (top of descent) VNAV path engaged and descent began. ATC then cleared us direct ZZZZZ 12000 and comply with altitude restrictions on arrival. I selected direct ZZZZZ with abeam points; executed/LNAV. FMC showed direct ZZZZZ with no abeam points. I then advised my FO (First Officer) that I would activate route 2 rebuild arrival and try again. The result was the same. We decided to use the Fix page and monitor our altitudes. Suddenly; we see red and hear aural warnings of overspeed. The VNAV indicator on the PFD was yellow with a line thru it. I immediately pulled the speed brakes and throttles were at idle. The aircraft speed was reduced. We figured the VNAV failure caused the loss of speed protection. VNAV failed to re-engage until on final approach when it engaged without being selected. After gate arrival our mechanics met the plane. After we explained what occurred the mechanics advised the aircraft has a history of items related to our events. Knowing the history of the aircraft could assist crews. However; multiple failures and their relationship with each other is a challenge for all.
Captain reported multiple aircraft status messages in flight and a failure of the autopilot caused an overspeed condition.
