Computer freezes during gaming

every time I'm trying to play any game full screen, the screen goes blank, tells me to check video cable, and I'm forced the restart the system.:confused:

HEEELPPP!!!!

It would be helpful to have some information about your system- I can't work in a dark closet with the light out!!

What operating system are you using?
How much RAM do it have installed?
Have you checked the cable connections?
What video and graphics card does the system have?
Have you reset the resolution? The DPI? Anything?

Let there be light..
