I don't think that you should try to install any other distro, since you have tried the major ones already. Your vid card is not the olny link in the "X" chain. You may have to even edit your /etc/X11/XF86Config-4 file yourself. THIS
is a sample XF86Config file that I posted to my website for times like this. I got it from a Gentoo install I was doing (one day I will succeed with it). There are a lot of comments in the file so one can figure out what to do.
Here's basically what you need for X to work:
1)You need a mouse section. Usually yours will work no probs with the 4.x servers
2)You need a keyboard section. Default 104 keys will likely work (unless you need another locale/language)
3)You need your vid card identified properly (get it working and then go for 3d). You have an NVidia so your card likely has some drivers right on the NVidia site.
4)Your monitor must be identified correctly. The horizontal sync and the vertical refresh rates must be within the ranges your monitor allows (DPMS is a good option here, so it'll auto detect).
5)Your resolution and color depth must match your vid card/monitor combo.
Debian was the first distro that actually worked for me. I agree that the installer is a bit of a pain, but, believe me, if you have to reinstall ever again, you can use the Debian-installer for Sarge (the 'testing' distro, which is near prime-time now - as in the overly careful Debian developers think its almost completely unbreakable). It asks almost nothing of you (I had to configure my own network, as I don't do DHCP with my router - took an extra 20 sec). By the way, if you haven't already, install synaptic after X works. Its a nice front-end for apt-get/dpkg. It does the same things as the command line with the advantage of being more readable (and you can use your mouse, if you prefer it
Look in /var/log/XFree86.0.log and see what errors may have shown up (you'll need to be root to see this file. Post it here if you don't understand it and can't get things to work as is. If you could post your /etc/X11/XF86Config-4 file as well (perhaps the parts about your mouse,vid card,monitor and hsync/vrefresh at least), that will help to figure thigs out as well.
