Windows 7 Dual Display is BAD help

[willoxxx]

just installed WIn 7

I tried to connect my Lg 1080p TV with analogic cable (I use a 'old' laptop).

Now it's a nightmare. The tv display disapear every 1 second and the computer screen is not working anymore even If I unplug the analog cable and restart it....

What should I do.... A Laptop without a screen is kinda useless !

y would you install windows 7 on such an old laptop in the first place? Trying to find drivers for that will be a pain. I dont know why it is doing that. Is there any other monitor in the house you can use to try and narrow down the problem for me.
