You can change the resolution of your monitor by right-clicking on the desktop and choosing 'Properties'. Then, click on the last tab called 'Settings'.
1. right click on your desktop and click on ';properties';.

2. and then it should be the last tab (i cant check on this computer) that says ';settings'; or somthing like that. and there should be two screens. if you drag the button all the way to the right, it should make one screen bigger than the other. then click ok.
If it's not that much that's cut off the screen, try pressing F11, that'll get rid of unnecessary bits of the display.
u r system must be working slow and it has viruses i n sure so do format u r system and do full installation
