Posting the errors would be the most effective thing you could do so that we could help you. Just saying errors isn't very specific, and forces us to guess.
The processor probably isn't a problem. As already mentioned, you have the option of using a 64bit OS, then you should use that. When a new processor comes out, it might be a while till the OSes can use its full resources (like a 64 bit processor before the 64 bit OS), but it would still work at reduced capacity.
The graphics card might cause a problem with a graphical installer, but probably not. They tend to install at low settings, requiring no optimization. If your distro of choice supports it, do a text install and see if that makes any difference.
The largest area for a problem is installing to Satas on a mobo controller. If you created a raid1 or raid0 system with the motherboard controller in windows, that is most likely the problem. Having the newest version of any distro will help with the sata install, as more recent kernels have more current drivers for hardware.
