OK, try the following in xorg.conf

Section "Device"
  Identifier  "NVIDIA..."
  Driver  "nvidia"
  Option  "RenderAccel"  "True"
  Option  "BackingStore"  "True"
  Option  "DamageEvents"  "True"
  Option  "UseEvents"  "False"
  Option  "AddARGBGLXVisuals"  "False"

Those are the settings I've most often found to cause problems. You'll need the Identifier and Driver lines for sure, If I were you I'd try the 'Option' settings one-by-one, starting with the one at the bottom.

Also, if you have Compositing enabled in KDE, turn that off first.
