    Hi, my laptop displays vertical lines after startup then shuts down & repeats the cycle. I think it is related to my Nividia graphics driver, but not sure. What I have tried is;
    1. A full system restore to factory condition, recovered from the backup partition - this worked until I downloaded updates from HP, Windows & a Java update, then it went back to above problem.
    2. Then tried system restore several times & each time this works again until updates are installed.
    3. Went to Nividia website to download latest driver - this did not work. Rolled back the driver but this did not work either.
    Only way I could start the pc was by pressing F8 on startup & going into safe mode with networking. When I did this the resolution was much larger than normal.
    Latest problem however is, now it will not start at all, screen stays blank. I do not have recovery discs.
    System is: HP Pavillion DV9500 notebook, on Windows Vista Home Premium.
    Any help much appreciated, Trevor.:confused:

    The much larger than normal appearance of Windows in Safe Mode is quite normal -- it's not a problem.
    It does that because in Safe Mode (or Safe Mode with Networking) Windows doesn't load any third party drivers (including the graphics driver).
    It loads the default Windows graphic driver instead, which has a fixed low resolution and low colour-depth. It just lets you get Windows started so you can remove a corrupted, buggy, or conflicting third-party driver on those occasions when normal Windows won't start because of a driver problem.

    I would restore using the HP factory recovery partition again but do not update the graphics driver from HP or from anywhere else.

    Thanks for the reply Pip.
    I eventually did a system recovery from the backup partition (had great difficulty in getting laptop started), it worked for about half an hour before the old problem of vertical lines occurred. This happened soon after a Java update. I re-started in safe mode & did a system restore to remove the update but this did not fix problem. Do I need to repeat the system recovery & not install the java update? Could the Java be responsible for this?. The graphics drivers are now the original drivers.
