Try running a memory test from the bios. If the memory test passes try reinstalling routeros with netinstall. If the memory test fails then it is a bad board.

I have no problem with memory test, its all OK.

The routeros reinstall using netinstall was made, but after this the boot freeze on the “services startup”.

Any sugestion ?

thanks

Have you tried using winbox to find it after it says starting services? I’ve seen serial port settings not being correct cause it to hang there. If winbox doesn’t see it I would try doing format nand from the bios and doing a netinstall one more time. If it still freezes up I’m not sure what else to suggest except..
