Wife would never allow checks or any bank stuff on a PC unless I built her one and it never ever got on the internet.
that PC has been in the bedroom for years now. no problems
You know what.... come to think of it... she still don't put the check book on it.

I did buy last year a Max one touch 500 gig external hard drive.
Very simple to use.
plug it in USB port.
auto run asks a few questions and you are set.
I have mine back up every Monday (automatic)
you can have it do more often if you like.
cost like $90.00
I know times are tight but still worth saving up $90.00 and buy one.
to bad Wal-Mart don't have lay a way any more.
check if Kmart has one, but I doubt they do.
Try and stick in your windows CD
do not do a fresh install... do a repair windows
This has worked for me in the past.
edit on after thought.
also a Linux CD will boot.
save data from hard drive with linux boot cd.
most linux cd has a cd burning program and will read files off hard drive.
It might not run files but it will see them and let you back them up
