The problem with the cursor

The laptop was risiti the cursor. Precisely how to misiti, after a certain time (4-6 seconds) the cursor stops for a moment, and again continues to move. The problem is not the mouse, because the touchpad too. The problem seems to be in the video card drivers (AMD Radeon R5 M330) . After buying the laptop the wood was already installed but when I updated to the latest version, the cursor began to freesite. Reset Windows seven, with DriverPack set wood again freezes. I tried to download AMD Crimson - the problem has not disappeared. Don't know what to do. Can set graviera older? But none of my old drivers not found.
