Hi, Rik

Goto Windows Start bottom left bottom corner of your Screen, click on it, Control Panel, Display, Settings, Advanced, Troubleshoot,

Hardware Acceleration, Set it to None or second dot.

Mine is set to Second dot and I unchecked the Enable write combining also, not sure about the write combining been-a-while since I look at

this.

Dont forget the Apply button then OK.

Hope this Helps, Chip
