I am having TurboC installed in my system. Whenever I try to run a program written in C++ using graphics.h,
the screen goes blank and my LED monitor displays a change to VGA mode and suddenly displays "NO SIGNAL" and
return to normal mode when I press "alt+ctrl+del" only. I have to stop the whole IDE to get back.
I can't figure out what the problem is.
Looking for some help.

Thank you.

Why? Sounds like that old ancient compiler is not compatible with modern computers and modern graphics cards. If you want to use that compiler then try to find yourself a 30-year-old computer, one that was made in the 1980s or 1990s.
