  Hello Lewie,

  Thanks for posting your query in Microsoft Community Forum.

  1. What is brand and model your computer?
  2. You did it any significant hardware or change software on the computer before this problem?

  I understand that you lose your screen when you play a game. This happens usually if the installed graphics driver has corrupted or unstable. Therefore, I suggest trying the following methods and check if the problem persists.

  Method 1: Run the tool material and devices

  Try running the next fixit and check whether the problem is resolved.

  Hardware devices do not work or are not detected in Windows

• Satellite U500-17F: problems with the new HARD drive

  Hi everyone, I got some troubleshooting with my Satellite and a new drive, I bought recently, because that is already damaged because of too many bad sectors. One is a Western Digital Scorpio Black 320 Bg (WD3200BEKT model number). It should be a fast reader but is not with my Satellite.

  After having mounted the drive in the laptop, I ran a new installation (with full disk format} Windows 7 (64 bit) with all the necessary drivers (that I downloaded directly from the Page of Support Toshiba.)

  The problem is that the laptop needs a lot of time to start and also to disable, and whenever I try to run an application or start a program (for example Firefox, or just a few windows applications), the laptop freezes for about 30 to 60 seconds, the drive no longer works (you can hear leaders put in position 'parking' and the HDD LED control is constant) ", no lights flashing).

  It seems that the drive (during this 30-60 seconds) in something as a stand-by mode. I ran a few Western Digital diagnostic tools and the car looks all right to 100%. It works also without any problems in the other laptop (HP Pavilion DV6500). Could this be a problem with the controller (Intel ICH9M - E ATA AHCI controller) driver?

  Any suggestion?
  Thanx

  Hello

  You use the latest version of the BIOS?
  Please check if you need a BIOS update. Of course I read in a few discussions on the similar question of Win XP you use Win 7 but its value to check the update of the BIOS and U500 series.

  In addition, I recommend check you the power of Windows 7 options.
  Disable in the power profile that you use power saving HDD.

  Just a question:
  You use the option AHCI in the BIOS?
  As far as I know it of possible to use either a compatible SATA AHCI mode.
  AHCI must be used because this option would use full SATA performance.

• Problems with the network controller

• Dell Latitude E5500-problems with the IDT audio driver

  Hi all!

  I use Windows Vista 32bits on E5500 and everything works fine with the big exception of the audio driver. I used the latest version for this laptop which is A15, no other versions are available on the downloads page. The pilot is very unstable and crashes all the time. Pressing the sound keys does not change the audio levels instantly as expected. There is a noticeable delay in the volume control after I pressed the button. A few 4-5 or more seconds after I press Volume upwards or downwards until the press is registered. A very weird situation and nothing helped so I deleted the audio driver of Dell. I use the default Windows driver now and so far everything is ok.

  Everyone has experienced a weird behavior like this on the same computer laptop? Do you know where I can find an old audio driver for E5500 so I can test again?

  As the system software Dell-is important on the audio system or not so. I installed it after a recommendation in the audio FAQ here on the forum. Thanks for all the tips!

  old audio driver for E5500

  Very good selection here

  http://downloads.Dell.com/published/pages/latitude-E5500.html

  All most recent drivers dated IDT must be removed from the hard disk or at least the drivers folder before installing an old date one.

  With the Intel chipset driver, was important for XP, not important for 7, but not sure about Vista.

• Problems with the Ethernet controller and PCI Satellite L30-10 X device driver

  HelloW!

  Sorry for my bad English, I'm from the Russia.
  A few days ago, I bought Satellite L30 - 10 X with W Vista on board. In my opinion, that this OS does ' t very good on this computer, so I install W XP.

  I have some problems with drivers. At first, I don't know which model I have: PSL30 or PSL33? I have download all the drivers for the two models. But after installation, computer doen't find the drivers for the Ethernet controller and PCI device...

  Hello

  Satellite L30-10 X belongs to the series of PSL33E. This number located on the label on the bottom of the device!

  You must choose this number in the form of driver download for XP compatible drivers.
  I put t know why you are not able to install the LAN driver. I have the same laptop with Vista and I've install the XP and all the drivers will work perfectly.

  I assume that you have installed the drivers in the wrong order. Please take look in the Toshiba installation instructions txt file. In this order, install the driver! This is important.

  I think that you should install XP again to ensure that the registry clean, then download and install the XP drivers compatible as mentioned in the installation instructions file.

  Good luck

• Device Mgr shows a problem with the graphics card

  Mgr. device initially says Code 10, I downloaded a driver (zipped) website of the SiS to 2003 (in the era of the PC)

  Right-click the compressed file, the shortcut menu contains the option "unzip" the files... Unfortunately these just led changing code code 10 code 1... basically the same problem I got it... either the pilot is wrong or not installed.

  Tried again, using Cnet, it was a similar vintage but this time "Winzipped.

  So that I could "unwind" that zipped, I can't do the same thing with the Winzipped file, the shortcut menu does not include an option "unpack".

  Double clicking on it opens a ' run ', which opens the "Winzip self extractor" that has a button seems fair to transfer the file 'compressed' to another location.

  This has the effect that the file is invisible to the driver installation wizard.

  Question:-how you uncompress the Winzipped file so that the driver can be installed?

  Question:-how to install a driver for this graphics card?

  I finally managed to find a driver package actually installed and friendly user who was not compressed with the 'winzip' dratted unfussy... Wow! almost as good as Linux!

• HP LaserJet 4100: Problem with the universal print driver

  Desktop: HP Envy 700-214

  OS: 10 64-bit Windows

  Printer: HP LaserJet 4100 (with a USB to parallel cable)

  I was able to properly use my LaserJet for Windows 8.1 through my Windows 10 crossing (which I upgraded to about 18 months ago).  Quite recently, I welcomed Windows Installer a upgrade, and at this time there, I lost my ability to print.   It has been on my default printer, but gave an error message when I tried to print.

  I tried to "Add a printer" and selected the HP 4100 connected to the LPT1 port.  It would not print a test page, and the printer does not like in the reception of data.

  I then tried to install the (PCL6 and Postscript) universal print driver with similar lack of results.

  I tried uninstallinDeg and reinstall the drivers, but once again no joy.  Incidentally, although I'm going to Device Manager > printing queues and remove the drivers, when I set up an application like Word and select the Menu printing, many copies of drivers rest yet.  When I go to remove them using the printui/s/T2, it is said that they are currently in use and cannot be deleted.

  Yet once again, I repeat - it is not a hardware problem because everything worked well before Windows upgrade.  I just need to find a way to reinstall a driver who will speak to my printer.  It of frustrating because I was able to do that before, but may not know what I am doing wrong.

  Thanks in advance.

  Hello GaryLynn,

  You saw did a lot of things to try to solve this issue.

  However the USB to parallel isn't anHP officially supported connection type.

  in any case, what suggests I´d, is that you try this:

  • Unplug the hybrid cable that you use
  • Uninstall all copies of the printer and its duplicates.
  • Stop the print spooler by using the services on windows (type on cortana services.msc) locate print spooler and stop it
  • Go to run and coil type, look at the Printers folder and delete all the files that are there (if any)
  • Restart the spooler to print services.
  • Download and install this driver package
    http://h20564.www2.HP.com/hpsc/SWD/public/detail?swItemId=FP-148007-1
  • Turn on your printer and connect the cable.

  After this exercise, check to see if windows 10 has managed to find the best driver to use your printer.
  If widows did not automatically find it, try the manual on add a Printer Wizard.

  If not reading as LPT1, check ports either USB00 ' # ' or a port DOT4, those who should be the ports to use.

  I hope this helps you get your printer going again.

  Thank you
