Disabling aero theme would probably solve that little bit of artifact on the screen.
It would make windows look ugly though.
apparently unlike most good registry scanners and tweak tools tune up util doesn't even have a undo function. Apparently the only way to undo what it has done is a repair install or a system restore to a time before it was installed.
For now let's just hope removing it's components will help stabilize you.
A repair install is really starting to seem like the easiest fix here. Since it's a new installation the odds of losing any applications or data in the repair is pretty much zero.
One final thing.
Have you tried this?
