Came to that app because it is an old mobo and the drivers on MSI's website are outdated. As for iGPU and Ethernet NIC I went to Intel's and Realtek's website respectively, Realtek's official web page does not list a driver for that NIC (8111 I believe it was) but unofficial realtek.cz does, and it's more recent than MSI's one.
Anyway it's worth noting that all these driver updates from sketchy sites did not solve the problem, and the problem existed prior to installing them.
