Anyone can help me fined root case and rescue this router?

What firmware version are you running?
Have you tried using different cables and different devices?
Are you sure ALL ports scale down to 10Mb ?
If you add Rate column in interface/ethernet view, you can see them at a glance.
i have try fw 7.8, 7.10, 7.10.2 and 7.18 are the same.
yes, all port from E1 to E5 the same, all are received 10Mb and can not get data to ping and searching by winbox
In that case, see if you can create supout.rif (or of reboot happens, autosupout.rif should be there) and create ticket to support.
I would start with other cable. Checked and good one 
If all ports at once go down to 10Mb ?
Doesn’t sound like a cable problem then.
Unless we are missing some info…
have try other cable is the same. note that it running normal get link speed 100/1000Mb before down speed . and after that it can not login and loss service. it is so strange
yes, i was send this file to support mikrotik team. i hope they will find the cause and support me solved
thanks
