same problem
Hi there! I have the same problem in my HP 9230, so I contacted HP online chat and they told me to download some packages for bios update and new nvidia drivers. I'm still downloading it but I guess new drivers will make it ok! Maybe the files are the same, but I'd check with HP for better instruction:

Hope it works and we can go back :pilotfly:and :joystick:!!!
Cheers!
