Vista won't sleep

I believe it is a vista software problem. Originally unable to prin
saved doc. & docx Files & web pages on my computer; shared compute
would print everything: my computer would go to sleep after 30 minute
as set in power settings just like it was supposed to
After much trial and tribulation (frustration) all is working fine o
the printer situation for both networked computers but my computer wil
no longer go to sleep as showing in settings.
MS appears to be having problems getting vista software to be a
problem free as XP and always will be glitches. Coupled trying to pus
64bit while still maintaning 32bit support and 3rd party software i
going to be a challenge for quite a while
If I figure anything out I will post. Still need to verify tha
uninstalling a couple 3rd party software programs/or which one correcte
