I have been running Windows 7 since release (almost) on an Intel Core 2 Duo E6600 no problem. I recently upgraded to a Core 2 Quad 8300. When I tried to boot, Windows did not start and displayed a screen that said the installation was corrupt and could have been caused by a recent hardware change. So since it had been while anyway, I did a format and reinstall. Since doing this, I am unable to get Windows 7 to run on my machine.
It installs OK, but on the first time startup, I get a blank screen after the "Starting Windows..." display. My monitor then goes into stand-by (indicating no video signal). This has happened every time after multiple retried installs. If I try and boot in safe-mode, it tells me I cannot run first time setup in safe mode and just restarts.
The strange thing is, I can install my version of Windows Vista that I got with the computer originally just fine. That boots and works all well and good. I think that it is the hardware change that is the problem, but I have no idea why that would be or what I can do about it.
