Lenovo 3000 c200 replace mainboard 41w1389 on 42w7673

Hi! My laptop Lenovo 3000 c200. Mainboard 41w1389.

I'm having problem with my keyboard/USB. When I press any key on the keyboard, that instant all USB devices are disconnected. And soon after I unpress it, the system detects all USB devices like they were just plugged in. I say all USB devices, cause it doesn't matter USB mouse or USB drive, they all get disconnected.

otherwise, I used the wireless lan to connect .it get very slow speed.

how can i solve these problems?


P.S. can i replace  my mainboard 41w1389 on mainboard 42w7673?
