6 months ago we experienced exactly the same thing. CCR began to reboot and persisted even after the power supply was replaced. Optically, we saw that the capacitors C1442 and C1443 are inflated, so we had them replaced with new and better ones. Since then, everything is without problems.
Today, we preventively replaced another CCR in the data center. When we opened it, capacitor C1442 is inflated again, but it still works. As a precaution, we have the C1442 and C1443 replaced again with new and better ones.
Request to Mikrotik developers: if you use the same capacitors in today's CCR1036 models, please use some higher quality ones. It is a great pity that because of this the whole device stops working even in 1-2-3 years, while the device as a whole is of good quality. It spoils the good name of Mikrotik. Thank you for understanding.
