Problem description:
1. The HP logo not visible during start-up
2. Laptop display remains blank
3. No indication that the Vista is loading
Analysis:
1. On connecting a external monitor the display appeared and with two options. The first message implied Windows files may be corrupted and that I attempt to restore. I tried restoring and it failed. The second message implied that I could continue to load windows. This worked and Vista came up. At this point the laptop display also worked!! Why did restore fail?
2. I restarted the PC and entered BIOS. A comprehensive scan of hard disk drive test did not find any problems.
3. At this point I suspected the display driver. I went to safe mode and reverted to a earlier NVIDIA GeFore 7600 ver. 7.15.10.9815 - 2/27/2007
4. On re-start, HP logo appeared and Vista is working. I got the message ''Display driver has stopped responding and recovered: Display driver nvlddmkm has stopped responding and has successfully recovered.''
If you can help me resolve this problem it would be great help.

There have been many issues with HP laptops. Load Safe mode and go to Hp.com find your models updated bios. Load the updated bios as well as the updated video drivers. This will limit some of your problems but will not resolve any underlying GPU issues if your system has any. I suggest you check to see if your unit falls under the Limited Service Enhancement for certain HP models. They will replace your board for free. But the first thing they will ask is what version of bios you have. Good LUck! Ruben
