Cannot use Screen & number or computer locks up.

[Cyclerider1]

When I run a program with Screen 8 or any screen with number it turns black and freezes up or will come back up with this:

16 BIT MS-DOS Subsystem
Microsoft Quickbasic
the NTVDM CPU has encountered an illegal instruction
CS: 9196 IP: 016f OP: ff ff 96 ff 20
Choose close to terminate the application

I don't know what is wrong.
Could anyone help me?

You cannot run fullscreen modes in Windows since VISTA was released. Get Dos Box to run them or use a program like QB64 to run your code.
