Ya, the other computer is Windows XP. 

When running xvidtune this is what I get:
Vendor: Monitor Vendor  Model: Dell1704FPV (Analog)
num hsync:1, num vsync:1
hsync range 0: 30.00 - 81.00
vsync range 0: 56.00 - 76.00
Video are not settable on this chip

What does the last line mean?  And with these settings what would my 
monitor lines look like in xorg.conf with these settings?  This is what 
it looks like now:

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Monitor Vendor"
        ModelName    "Dell 1704FPV (Analog)"
        DisplaySize  340        270
        HorizSync    30.0 - 81.0
        VertRefresh  56.0 - 76.0
        Option      "dpms"
EndSection

Section "Device"
        Identifier  "Videocard0"
        Driver      "vesa"
        VendorName  "Videocard vendor"
        BoardName   "VESA driver (generic)"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth     16
        SubSection "Display"
                Viewport   0 0
                Depth     16
                Modes    "1280x1024" "1280x960" "1152x864" "1024x768" 
"800x600" "640x480"
        EndSubSection
EndSection




Sorry for my ignorance, I usually don't install X.
On the windows machine, my settings are 1280x1024 at 75Hz refresh rate 
if that helps.
