I'm running windows XP pro. I up graded my video card to Ati Radeon 9600 Pro 128MB. I picked up on ebay for $30. On the boot screen the lines are up and down all over it is even hard make out. The next screen is fine working great. Then the windows load screen is messed up. The welcome screen is fine and clear of lines then right before going to the desktop screen the mouse pointer disappears it is their but can not be seen the lines are gone but so is the mouse pointer? Every time I reboot more lines are removed still no mouse pointer? What is this.
