Wubi keeps freezing. REISUB doesn't work. Any safe, easily undoable alternatives?

http://askubuntu.com – I ran the installation for Wubi from ubuntu.com on my Acer Aspire One 722. It works fine every now and then, but more often than not the OS freezes.

But the freeze occurs either right away or after a while, maybe when I'm downloading something. I have tried a fresh insta (HowTos)
