Hi. I was watching a streaming video today when my Laptop froze up. It was unresponsive and I had to reset it by holding the power button. Upon reboot the display was acting funny. I had unusual patterns of blue pixels during start up when it is usually black background and white text. The machine then failed to start up and I got a BSOD memory dump. I tried booting a few times with similar experience. I then booted into Safe Mode successful. At this point there was also strange pixel patterns on my desktop background which changed if I cursor'd over them. I checked to see if the Display Driver was up to date. It said it was. So I decided to uninstall the Display Adapter/Device and reboot, thinking the device driver would automatically be reinstalled. Now when I boot I get nothing on screen at all. Nothing. Not even the usual white text/BIOS messages or any strange pixels. But after a while I hear the usual tones that I get when the machine arrives at the log in screen. So I think its booting but just not displaying anything.
I wondering if I should unplug the graphics card and reinstall to see if that helped it detect new hardware, but I do not know how to access the graphics card in a laptop. If I take the back covers off the laptop I see 2 hard disks and some RAM chips but not a lot else. The machine is an HP Pavillion model no. dv9689ea.
The sticker on the back of the machine says:
Product: HP Pavillion dv9500
The machine has Vista SP2.
I would really appreciate if anybody can help me to get my display working again.
