Hi,
So recently I have been using a laptop (which has a broken screen) as a secondary system with an external monitor.
The monitor only comes on once in Windows, which was fine.
But Windows on the hard drive got corrupted, so I put another hard drive in the laptop which I know has a working copy of Windows 7 on it (I also tested it on another machine before putting it in the laptop).
When I turn on the machine I hear the hard drive spin up but I get no picture on the external monitor.
I cannot see what the computer is doing as the monitor only comes on in windows so I cannot enter the bios or boot menu.
Any help would be greatly appreciated!
Thanks!

Thanks for your answer but the laptop is only a core 2 duo and the rest of the laptop is in very bad condition.
I am only using it as a very light secondary machine.
