    I don't want the drivers.  I mean the software.  The drivers you get from the page server 2003 and the software from the page I referenced.   Otherwise, you need to contact HP, as they provide that software, not Microsoft.

    I just did an itunes update, now I can't find my music. Help please.

    You will need to provide more details, but here is a screenshot of my iTunes (top-left) window

    The row of small buttons 'Library' has been replaced by a drop-down box, when you select the library view.  Music is selected in the screenshot.  In the sidebar, under the library, you can select the view to use for the library.  In the screenshot, songs is selected, which presents a library as a list of simple songs with columns.

  • Having previously worked now Readyboost does not activate flash on Win7 ultimate x 64

    Hi people,

    I use a SanDisk cruzer micro 8GB flash drive for awhile with win7 now and I alternate between use as readyboost and storage.

    But recently the readyboost option stopped on the AutoPlay list. Then, after a restart it came back, but every time I select the flash drive > properties, there is no readyboost tab to be seen.

    The only changes to the system are that I added a USB printer and scanner USB. What the hell is happening?

    I tried to format, reinstall SanDisk U3 launcher, I tried diskpart own all etc, etc. But nothing seems to give me the option
    to enable readyboost.

    Anyone got any ideas? The really strange thing is that readyboost was working fine last time I used the flash drive with Win7.

    Any help much appreciated.

    Hi Khaled,

    Nope, none of that helped.

    But I think that the reason for the problem of readyboost is that Win7 didn't like the fact that I had hacked an install of my Nikon Coolscan 5ED the USB and Canon LIDE35 USB devices to work under Win7 using old drivers 64-bit XP and Vista.

    I have now re-installed Win7 and I can confirm the two my SanDisk Cruzer Micro 8 GB and 16 GB USB key work correctly with readyboost again.

    On the plus side, I realized that I wasn't not take full advantage of my computer RAID storage. I have a controller matrix RAID Intel 10CHR and after having read up on the site intel I have now installed Win7 with a RAID0 to 3.4 volume and super fast and a volume RAID5 1 TB on a range of 5xHDD 5xHDD.

    anyway thanks for the help guys.

    Hello

    19 code means there is a driver conflict such as two devices attempt to use the same resources.

    Please make all below even if you have done some before as it is often the set of operations which solves
    the question.

    Try this - Panel - Device Manager - CD/DVD - double-click on the device - driver tab - click
    Update the drivers (this will probably do nothing) - then RIGHT click the drive - UNINSTALL - REBOOT
    This will refresh the default driver stack.

    Normally the above will solve this problem otherwise working your way down through them, even if you did
    them before.

    I've been putting together several booklets recently and everything was spell very well. Today I'm going to press, and just started to come on one side. Do you know why it just stop working all of a sudden?

    Check the settings in the print driver. Duplex (two-sided) printing is handled by the driver, not by InDesign.

  • my hp officejet 4500 printer was working now, it will not print?

    I bought a hp officejet 4500 it was printing and receive faxes, now it does nothing?

    Sometimes, for reasons unknown, the Printer Spooler service becomes invalid. To check which is the case, follow these steps:

    1. click on the Start Menu, click Run, type "services.msc".

    2. in the Services pane, click on "Alert" and scroll down until you see "print spooler".

    3. click on "Start service" or "Restart Service", as the case may be.

    The print spooler must be enabled.

    Check if printing is enabled.

    Hope this helps
