New 7850 installing drivers

Hi guys,

Just built my first computer in a long time, consists of the following:

XFX Radeon HD 7850 2gb
ASRock Pro4-M motherboard
Intel i5 3570K
Samsung 830 256gb SSD
Asus Bluray Burner BW-12B1ST
Patriot Viper DDR3 1600 8GB
XFX Core 550W
Fractal Design Core 1000

I've installed windows 7 and updated it, seems to be doing OK. The problem is when I tried to install AMD drivers, windows doesn't finish loading. I can see the splash screen, then when it flickers out to go to the login screen it never shows. I've tried 12.10 and 12.4 drivers.

I have it only hooked up via HDMI to my projector. I have a hunch it's related to this, and I've tried various orders of starting up the PC vs projector, unplugging and plugging in the HDMI cord, etc. I don't have any sort of monitor display that accepts displayport or DVI, and my card didn't come with a DVI to hdmi converter.

Any suggestions on what to do? I can still load up in safe mode and uninstall the drivers, but I'd like to game on it this weekend if possible!
 
Here's an update: I was able to get a dvi-vga adapter and run a long vga cable to the projector. The dvi/vga combo works, and I have the HDMI cable still connected, but there's no way for me to get the HDMI connection detected (which is the connection I want to use). Any help?
 
Is the HDMI Version of your cable compatible with the projector? Perhaps the lower resolution bios screens and splash screens are displaying and then when the GPU pushes higher resolutions you run out of bandwidth across the cable.
 
Yes, I think the cable is OK. I can use the cable with my laptop at 1080p, and I believe I switched the generic VGA driver to 1080p on the new computer without any problems either. It seems intimately related to the catalyst drivers.

I've been doing some reading and I think it's related to switching between DVI and HDMI, but I'll try moving to my hdtv and using a shorter cable. if that seems to work then it's like a cable or projector issue.
 
Just for resolution sake here was the underlying problem: the catalyst drivers need to detect an audio device for the hdmi connection to work, since my projector had no audio it did nothing. When I plugged it into my monoprice hdmi switcher it detected it and worked like a charm.

Never expected that adding a component in the middle of an HDMI chain would actually help the situation...
