Windows 7 Install (cannot find signal)

I was trying to install Windows 7 on a formatted PC, I got through the first part of the installation but just as it got to the last thing to install my monitor said 'cannot fnd a signal' then the PC restarted, I could see the boot up screen, it then goes to the windows 7 start up screen but straight after it my monitor goes black and shows 'cannot fnd a signal' again, so I can't finish the installation :S

I've tried starting up in safe mode but it just says the installation cannot be completed in safe mode and my PC restarts.

I have a similar problem and I'm waiting for a solution :)

You were watching the install on your monitor to that point, right?

If monitor loses signal, it sounds like a video card or tv tuner was loaded at that moment and has a different output which is not connected.

If you have onboard graphics, remove the card(s).

The problem was that my pc was connected to my television via the hdmi cable so i guess the computer was graphically confused. I then just had to boot from the installation cd and start the installation again. It worked for me!
