other software run fast
ex: stencyl3 , office, painter ...
it seems Video card or directx problem
when i install construct2 in win10 , the same hardware pc
it runs smooth.
Nvidia is still providing support in the latest drivers, so it's unlikely to be a driver issue (still could be but unlikely).
It might just be seriously underpowered.
As an example compare your card against mine using Passmark values - I have the GTX 970:

Just something to consider.
If you have access to another card, it might be worth testing it to see if it makes a difference.
