Ultimaker 2 started acting strange

[sarunas 1]

Hi there,

I bought Ultimaker 2 in 2015 august.

It was printing fine for like 3600 hours.

Recently it started acting strange. Sometimes when printing the head starts going in places where it should not go. Sometimes feeder starts feeding too fast. Sometimes starts just feeding plastic all over the place.

On the back side of the PCB there are some brown areas near the drivers but nothing very serious.

Cables and connectors look fine - never touched them.

Maybe the board needs some additional cooling?

I use a lot Pause@Z function - may it have some influence on it?

I maintain it properly - clean, lubricate, etc...

Cura 2.3.1

Update: I suspect that my SD card is wearing out. Will see what I can do
