cannot install x86 but can x64

I am have been unable to install Windows Vista X86. I have successfully installed Windows Vista X64. I just have had network problems due to no drivers being available for much of my hardware, and if there is one available they have not been signed and will not install. So I decided to install Windows Vista X86.
The problems with Windows X86 is that I cannot get it to install. I initially downloaded the install disk and burned it to DVD. Every time I try a new install it goes past the first screen which asked about language and key boards. I click next and then it says please wait and that is it. After about 15 minutes I get the blue screen of death. This happened with the Microsoft disk and the ones I burned, all at 2x speed and past the checksum. This made no difference. I am trying to install on a 80 gigabyte western digitial 7200rpm hard drive. I have 4 gigabytes of ram, a XFX Geforce 6200 Nvidia graphics card with 512 megabytes of DDR Ram. A AMD Athlon AMD 64 X2 +3800 process, on an Abit AV8 motherboard. I have tired to upgrade a Windows XP Pro and it goes all the way through and on reboot that is when I get the blue screen. I would use the X64 if I could get the Network to work. The NIC card is on the mother board but did try several other Linksys 10/100 just cannot seem to find a driver that works. The onboard NIC shows it is working just cannot ping anything including the router which works fine in Windows XP. I am totally at a lose.
If anyone has any ideas it would greatly appreciated.
