Any chance you can help me my warranty expired, please help Val
I had the same problem. You need a new graphics card.
HI
Please run a diags on the system by pressing FN+power button and posts the results. Also try booting to safe mode by pressing F8 when you start the system posts the results, I will be able to definitely help you with this.
Thank you

with the error code what it means is that, when the "do you color lines" i believe either u dint press y for yes or press n for no or did not give a response. does the screen looks fine in the diags??? if it looks fine its an issue with your operating system.
try to boot to safe mode and check??
