All of a sudden when the laptop was "awaken" from the screensaver the display switched to lower image analysis with lots of flickering going on. After rebooting/hibernating everything went back to normal. I updated my nvidia driver, thinking that could cause the problem.
It looked that it worked fine but today after booting the pc, the screen appeared half grey/blue with vertical lines all over the screen, couldn't log on or anything!
After more than 10 tries of rebooting everything works fine again. I rolled back the driver but I am afraid to switch the pc off again.
Question: could it be a hardware problem? Is my monitor dying?
My system:
HP pavillion zv5200
AMD Athlon 64 3400+

NVIDIA GeForce4 440 Go 64M
