Assembler and tutorial

Can anyone link me to a good assembler and tutorial for Asm. I've tried Google but all I'm finding is broken links and DOS programs.
I'm using a 64 bit processor and am already familiar with programming in general.

One way to get started is to get a very lightweight C compiler (NOT C++) like the old Turbo C for DOS.  It's still around.

Then write some very simple C programs.  Compile them with:
 - all optimizations disabled
 - debug symbols enabled
 - assembly listing enabled

And then look at the output.  The assembly should line up pretty much perfectly with your C code.

Then, I believe that Turbo C includes some shit like "turbo assembler," so you can take a shot at writing some assembly from scratch.

Or he could use something newer like MSVC and MASM and maybe some debugger like OllyDBG. It'd at least be 32bit x86 asm, and the output MSVC generates for C is pretty easy to understand anyway, even with full optimizations on and no assembly listing (disassembling the exe).
