Vista - service pack 3 failed install

I installed service pack 3 and it had an error message. The screen will not
allow windows to boot. for three days now it says reverting changes and stays
there. It won't even boot into safe mode. What do i do? how do i even get
past it to save my info and reformat?

installed and where did you get it ?
If you downloaded something from a none Microsoft site claiming to be PS3
for Windows Vista then you have probably wrecked your install and will have
to do a clean install to clear out the mess.

I guess it's Vista SP2 that you're talking about since you say it was
through Windows update.

Your best bet is to boot a Vista DVD and try the repair tools. You might
try a Startup Repair first. If that fails try using System Restore to roll
back.

See http://www.bleepingcomputer.com/tuto...torial148.html for
information about how to run these processes. If you don't have a Vista DVD
you can try to borrow one. It is also possible to download an ISO file to
burn a DVD with the repair tools. That will, of course, require access to
another working computer. See
