Unexpected reboot after deep sleep

[Guest]

Using my upgraded Vista computer (XP to Vista Home Premium), I had no trouble
with it until one day, I click on my sleep button and woke it up founding
that my computer have restarted!!!. It would ask me to go to safe mode or not
and I go on normally until I got to my desktop. The solution for it (from the
Windows Problem and Solution thing...) was to install this kind of Nvidia
Controller. I did this (I think) and found nothing have changed! Any possible
solutions to fix this. I'm getting very annoyed with this (restart my whole
project all because of it).

Thanks!

Suggest you set Vista power options so that sleep becomes hibernate until
you have a proper solution...

If you've used disc cleanup there can be a problem, it's in the knowlege
base. accesories, command 9run as administrator), type, powercfg -h on
