Why won't my computer screen turn on sometimes?

I have my computer hooked up to my flat screen tv, sometimes when i turn the computer on it wont show! Why?

  • Its a 46" screen, Sometimes when i boot up its fine other times it doesnt do anything. I just stays black. Then i have to turn the power off of the computer and shut it down the wrong way. I am afraid if i don't get this figured out, damage my computer or worse...lose data!!! Does anyone know why its doing this and how i can fix it?

  • Answer:

    i think its your video card. or the plug of the monitor are not in proper port. but if your monitor are in proper port. why don't you try auto adjustment.. if not clean your video card..
