It seemed related to colors so I did a spreadsheet with white, red, green and blue background fill pages.
Whenever I display the green background the display freezes downward from where the green starts and then begins to fade out. External monitors still work when this happens.
What could this be? mother board hardware? Bad LCD panel? SW error?
I've updated the BIOS.
Have not re-installed intel video chipset or NVidea graphics drivers yet.
Called HP service and I'm about 1 month out of warantee. (They offered a 2 year extension for $139 and I jumped on that) I'd just as soon not send it in since my last experience with that was not good. I also don't want them re-formating my HD or something since it takes about 3 days of work to get it back the way I want it.
Windows XP SP2, fully updated.
