nvidia driver fails to start X (blank screen)

This is my first post and I'd like to say thank you to all the people on this forum who have helped me in the past by lending there expertise to others. It seems i need that expertise again...

I recently bought a Nvidia Geforce 6600 GT which works (at low resolution) with the vesa driver. After installing the 64-bit nvidia driver ( successfully I changed xorg.conf to read:
Section "Device"
	Identifier  "Videocard0"
	Driver      "nvidia"
	VendorName  "NVIDIA Corp"
	BoardName   "NVIDIA driver"
        Option	    "ConnectedMonitor" "DFP"
Section "Monitor"
	Identifier   "Monitor0"
	VendorName   "Hewlett Packard"
	ModelName    "HP P4829J L1820 18.1-inch LCD Monitor"
	HorizSync    25.0 - 82.0
	VertRefresh  54.0 - 88.0
	Option	    "dpms"
Then when starting X I simply get a blank screen

Consulting the /var/log/Xorg.0.log file i find that the new nvidia module seems to be loaded
(II) LoadModule: "nvidia"
(II) Loading /usr/X11R6/lib64/modules/drivers/nvidia_drv.o
(II) Module nvidia: vendor="NVIDIA Corporation"
	compiled for 4.0.2, module version = 1.0.7667
	Module class: XFree86 Video Driver
I can only assume the problem has something to do with the hsync being out of range:
(II) Module ddc: vendor="X.Org Foundation"
	compiled for 6.8.2, module version = 1.0.0
	ABI class: X.Org Video Driver, version 0.7
(WW) NVIDIA(0): Failure reading EDID parameters for display device DFP-0
(II) NVIDIA(0): Monitor0: Using hsync range of 25.00-82.00 kHz
(II) NVIDIA(0): Monitor0: Using vrefresh range of 54.00-88.00 Hz
(II) NVIDIA(0): Clock range:  12.00 to 310.00 MHz
(II) NVIDIA(0): Not using default mode "1280x960" (hsync out of range)
(II) NVIDIA(0): Not using default mode "640x480" (hsync out of range)
(II) NVIDIA(0): Not using default mode "1280x1024" (hsync out of range)
(II) NVIDIA(0): Not using default mode "640x512" (hsync out of range)
(II) NVIDIA(0): Not using default mode "1600x1200" (hsync out of range)
... on and on
... on and on untill every resolution has resulted in hsync being out of range
This is how the Screen section is set up in my xorg.conf:
Section "Screen"
	Identifier "Screen0"
	Device     "Videocard0"
	Monitor    "Monitor0"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     16
		Modes    "800x600" "640x480"
	SubSection "Display"
		Viewport   0 0
		Depth     24
		Modes    "1280x1024" "1280x960" "1152x864" "1024x768" "800x600" "640x480"
I had previously had a Geforce 4200 Ti working with the nvidia driver without any trouble using the same set up so I find this new problem perplexing. Any help with this problem will be greatly appreciated.

Hopefully this will help out...

Hit this page => to get the modeline for your screen. Then modify Sections "Monitor" with the modeline the website generates. My nvidia card was bitchy about this so it's worth a shot...

Example (snipplet directly from my config):
HorizSync       31.50-48.80
VertRefresh     50-70
ModeLine        "1280x768" 80.14 1280 1344 1480 1680 768 769 772 795
Option          "DPMS"

Check if nvidia blank screen is actually a black screen

Hi guys. First post here. I have been suffering from the NVidia blank screen for a long time. Usually able to fix it by downgrading my xorg distribution as far back as I can find binaries for. Reading various posts it seems that it does not matter which NVidia card you have.

Working with Debian package xserver-xorg version 1:7.5+6 right now and just noticed something interesting:

When starting xserver with "X" or with "startx" I get what I thought was a blank screen. However, when running with "xinit" I get a black screen with xterm.

I think the black screen problem may be a problem with the XOrg init scripts and not actually a hardware or driver problem. Somebody please verify if their problem is the same as mine thusly:

#from a text-only console (ie. Ctrl+Alt+F1)
$ X -ac &  #run X with access control disabled and background it
$ export DISPLAY="localhost:0.0"
$ xterm
#press Ctrl+Alt+F7 to find your X terminal and check if xterm is visible there
