aspire sw5-173 MicroSD card connecting problem

Meichopath

hi, I am using Aspire sw5-173-648z

Last week I bought a samsung micro SDXC 128GB evo+ for my tablet.

It had worked well, there's no problem for a few days, but since yesterday suddenly SDXC card has been ejected and reconnected right away. and These things happen continuously. when this problem first happened, I thouhgt it is due to SDXC card itself. so I inserted another card but the result was same. and there's no problem when I inserted card into my phone.

Is this software problem or hardware problem? 

Currently I am using Windows10 home 1607 redstone

 

(I'm living in the country where aspire sw5-173 is not officially sold so I think I won't able to get proper repair service. please help ㅠㅜ and thanks for reading my sloppy english)
