every think was working fine till it suddenly gave me this error , what should i do to solve it,

am using windows 8.1 ,

thanks inadvance

What board is it, is anything connected to the board and have you tried other cables?

it arduino uno , I tried USBasp but it gives me that no serial connection is made

In the top bar of the arduino software, go to tool → board and tell me what is selected.

Under the same menu, change USBasp to AVRISP mkII.

am using the correct board , but it didn't work, the same error appears

Post pictures or a small video.
