If the restore to factory conditions doesn't work, I'm afraid it's a hardware issue. Unless, of course, you added the video card yourself, then it's understandable the factory setup doesn't work.
If it's the original hardware I'd contact HP Customer Service about repair.
It might be interesting to know if you can run Linux from a cd or dvd (without installing it).
Hi! I recently reset my laptop to factory settings because of some malfunctioning display drivers I couldn't get to work. Everything went just fine during the setup, but once it was completed I got a blank screen, which was also the case before the reset. It did seem like it managed to start up, I heard the typical windows sound, but didn't display anything at all. So then I tried to reboot in safe mode as this wouldn't load any of the bad drivers. Unfortunately after I leave the "safe mode" menu, a screen pops up displaying: preparing computer for first use... Secondly an error message appears: The installation couldn't be completed in safe mode, please reboot the computer.
I'm desperate to get some help on this issue as I've made several attempts to solve it, without any luck. Also when I connect my laptop to my TV screen, it briefly shows a blue error screen telling me something about the drivers. I can't exactly tell what the message says as it shows up for merely 2 seconds.
My laptop is a HP G72-a50SB and uses ATI Moblity Radeon HD 5470.
