Windows 7 Beta - No Video Signal?

So I had to RMA my 8800GTX (RIP 🙁 ), in the meantime I was using an HD3450, but didn't want to mess with drivers in Vista... So I tried the 7 beta key I had sitting in my e-mail.

Worked well... Now I have a replacement 9800 GTX, and I can't get 7 to give me a video signal outside of safe mode. I've installed the the card's drivers (it's recognized as 9800GTX/9800GTX+ in device manager), and I'm not sure what else to try. If I don't enter safe mode, the PC boots, I can hear everything, and pressing the power button shuts it down, but my monitor receives no signal (I've also tried turning the monitor off/on after boot - no dice).

Anybody else encounter this? I've been browsing various forums, haven't found much help.
 
are you using Win7/MS's drivers? or NVIDIAs? i'm just using whatever came from Windows Update. 1550XT and the 4350 i upgraded to (a few days in messing around with the beta) worked out of the box ...

can you try RDPing or VNCing into it at the login screen?

maybe try a different port? my GF 8200 onboard's VGA port is dead until i hit the desktop, IIRC (it's either just before or after the login)...
 
I've seen this problem when my videocard over powered my power supply. Maybe when it tries to turn on more features in the GPU the powersupply is crapping out.
 
Aye, I've had the same kind of power supply problems, but I'm having no problems whatsoever in Vista - this is absolutely a Windows 7 issue.

I had time to look into it more, and I do have NVidia's newest drivers installed. The problem seems to be that, according to display settings, my adapter is 'VgaSave' (which apparently signals driver issues)... but the 9800 GTX is installed correctly according to device manager 😵.

I've pretty much given up on it for now, wasn't too important in the first place, just irritating XD.

EDIT: It's a problem common to, of all things, those using DVI cables:

I had this issue installing W7 using DVI to monitor.
Vga to monitor worked fine.
Not sure if its a videocard type issue, W7 issue or MB type issue or ???
One asrock MB had no issue. Another with diff video onboard had the issue.
I had to install using vga to monitor.
 
I was going to say PSU also but if your card worked fine in vista.... My dvi to monitor worked in win7. Guess you could try that SVGA cable they refer to in the technet forums.
