Alienware m9750

Hi guys... need help!
Several years ago I bought this laptop and everything worked great until my GPU (7950 gtx) went bad. Recently I bought a new 9700m gt from ebay and had a MXM structure... bla bla... 30 second beeping. I've fixed that with flashing the vbios and fixing the hex string with an option that I've found on another forum.
Everything works great now except the booting for the second time. By second time I mean: when I turn on my laptop OS comes up and everything works. If I have to shut down/power up or restart I get black screen. I don't see alien head, no post screen, I can hear Windows welcome screen sound but no picture.
If I wait for 15-20 sometimes 30 minutes it boots up normally.
