Sys back on track - what now?

[Spanishcat]

A couple of days ago I had fairly critical problems that some here tried to
help me me out with (to no luck, however). Through memory and system
corruption Window's forgot its own validity ("This is not a genuine version
of... ") when I had three levels of ID for the product.
In the end after much trouble, a simple sys restore got it back on track.
It's taking a trip back to the shop, but in the mean time what should I
do; just not touch it at all so I can't possibly make it worse, or attempt
the Vista updates again?

The file scan still comes up with corrupted files but cannot fix and
repair all of them, so hardware problems are still there obviously, and even
after I restored successfully to the desktop it bluescreened within five
minutes.
I'd just like some general advice, maybe in the form of further checks I
can do until tomorrow (now that I have full access back). Any tips for
precautions I can take in the mean time - to steady the ship, so to speak -
will be welcome.

If your system is going back to the shop tomorrow, don't do anything else to
possibly damage the OS. Do you have all your data backed up? If not see if
you can back it up, but don't try and change any system setting or do any
more updates. That will be the job of the repair people.
