Hi,
I have similar (or not?) problem on my new system. When I start computer screen goes black after POST, sometimes later. I can manage to start Windows 7 installation, after loading setup files screen goes black and monitor is searching for signal. I cannot really check exactly what happens in BIOS as I have only limited time until everything disappear. I have only keyboard and mouse connected to PS/2 ports and monitor to video card. This is the moment where I completely stuck. Do you have any idea guys?
