Graphics artifacts cause by "damaged" user account?

[FlightDeck]

Hello,

Hope this is an appropriate forum for this topic...

If I switch to Adobe Photoshop CS4 from Adobe Lightroom 2.2 in Win XP Pro, I
get graphics artifacts on the Photoshop display. They are portions of the
screen from Lightroom, and cover parts of the image. If I zoom or pan, they
flicker yet stay there.

I can "clear" the artifacts by switching to any other full-screen
application and back to PS. They reappear the next time I switch from LR to
PS.

Updating video driver and from SP2 to SP3 had no effect.

Testing through Adobe Support's suggestions revealed that I can't re-create
the issue when using another user account on the machine. They said they
think the user account is "damaged". That would not be a good thing, seeing
as how it's the built-in Administrator account of Win XP... Does this
diagnosis make sense? And assuming it's true, how count I fix a "damaged"
Administrator account? Just the user profile? Or is it the account itself?
Didn't find any leads in the MS Win XP KBase...

Note that both accounts tested have admin privileges, the same desktop
display settings, etc.

Specs:
Win XP Pro SP2 & SP3 (both have same issue)
nVidia e-VGA GeForce 7600 GT KO 256 MB driver v.181.20 (current)
4 GB RAM, and using /3GB switch
3.2 GHz iCore2Duo

Thanks.

Artifacts are usually cause by a driver problem. Head over to www.guru3d.com
in order to post your question to a dedicated forum.

While there, look at the software Driver Sweeper. Video card drivers
tend to leave "leftover" files / settings when you upgrade them while
th older ones are still installed.

Smlunatick, thanks for the tips. I tried a full round of uninstalling the
drivers, running Driver Sweeper in Safe Mode, and then re-installing the
drivers, and the problem is still there.

As mentioned before, the problem exists in one user account but not in
another (both have admin privs). I'd like to focus on this "damaged" user
account concept. What things can I investigate to see why one Win XP user
account has the problem and another does not?

Thanks.
