i have an HP Pavillion dv7 with windows7. It is less then 3 months old.
Problem- Yesterday the screen went black while i was watching a video, but the sound kept going. so i restarted the computer, and the screen works until you get to the login screen it goes black again.
SO i called customer service at hp, and we worked on it for an hour.
We tryed multiple things, including system restore.
THe one thing that seems to work is when i go to the device manager, uninstall the display adapters, and restsart in normal mode, then i go and reinstall the ATI device thing in the recovery manager, but everytime after i reinstall the ATI display device thing, it ends up going black a little while later again.
Is the ATI display device broken or something? is there any way to fix this on my own? or should i just go to best buy and hope they dont destroy my computer.. lol
uninstall the graphics driver and all other ati software such as catalyst control center--then do not reinstall it--download drivercleaner or driver sweeper and use them to remove all traces of ati drivers--restart in safe mode and run drivercleaner/sweeper again--reboot and install the graphics driver to see if it fixes the problem
this usually is caused by updating graphics drivers without totally wiping out the old ones
