  If after the update is installed, you see always the same slow and jerky behavior, a Safe Mode boot removes the system caches that can help.

  After your Mac stops, wait 10 seconds, then press the power button.

  As soon as you hear the startup tone, hold down the SHIFT key. You must press the SHIFT key as soon as possible once you hear the startup tone, but not before.

  Release the SHIFT key when you see the gray Apple logo and progress indicator.

  -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
  -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.

  Vista and Windows 7 updated drivers love then here's how update the most important.

  This is my generic how updates of appropriate driver:

  This utility, it is easy see which versions are loaded:

  -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
  For each driver in the list, additional useful information is displayed: load address of the driver,
  Description, version, product name, company that created the driver and more.
  http://www.NirSoft.NET/utils/DriverView.html

  For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
  Control Panel - device - Graphics Manager - note the brand and complete model
  your video card - double - tab of the driver - write version information. Now, click on update
  Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
  Uninstall - REBOOT it will refresh the driver stack.

  Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
  with their own software and drivers and all other main drivers that you have.

  Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
  Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
  BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

  Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
  each installation.

  Always check in the Device Manager - drivers tab to be sure the version you actually install
  presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
  in particular that) so to install a driver - reboot - check that it is installed and repeat as
  necessary.

  Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
  manually by model.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

  Hi MAMARDA,

  Welcome to the Microsoft Vista answers Forum!

  I would like to ask you a few questions in order to get a better understanding of this issue so that we can better help you.

  (a) what version of Windows 7 use you?

  (b) what is the exact error message you are getting?

  Method 1: You can also try to perform a file system (scan SFC) verification tool. This tool will fix the system files are corrupted.

  Scan SFC enforcement procedure:

  1. click on the Start button

  2. on the Start Menu, click all programs followed by accessories

  3. in the menu accessories, right-click on command line option

  4. in the drop-down menu that appears, click the "Run as Administrator" option

  5. If you have the User Account Control (UAC) enabled, you will be asked permission before the opening of the command line. You simply press the button continue if you are the administrator or insert password etc.

  6. in the command prompt window, type: sfc/scannow then press enter

  7. a message is displayed to indicate that "the analysis of the system will start.

  8. be patient because the analysis may take some time

  9. If all the files need replace SFC will replace them. You may be asked to insert your Vista DVD for this process to continue

  10. If all goes although you should, after the analysis, see the following message "Windows resource protection not found any breach of integrity.

  11. once the scan is finished, close the command prompt window, restart the computer and check.

  Method 2: If this is a recent problem that has developed you can try to perform a system restore and check if it works very well.

  To restore the operating system to an earlier point in time, follow these steps:

  1. Click Start, type system restore in the search box, and then click System Restore in the list programs.

  If you are prompted for an administrator password or a confirmation, type your password or click on continue.

  2. in the System Restore dialog box, click on choose a different restore point and then click Next

  3. in the list of restore points, click a restore point created before you started having the problem, and then click Next

  4. click on finish

  Note: When you perform the system restore to restore the computer to a previous state, programs and updates that you have installed are removed.

  For more information, please follow the below given link:

  How to repair the operating system and how to restore the configuration of the operating system to an earlier point in time in Windows Vista

  http://support.Microsoft.com/kb/936212/

  Method 3: you can try to start safe mode and restore the system, if you are unable to do it in normal mode.

  For a safe boot, you can follow the below given steps:

  1. remove all floppy disks, CDs and DVDs from your computer and restart your computer.

  Click the Start button, click the arrow next to the button lock and then click on restart.

  2. do one of the following:

  a. If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you need to try again by waiting until the Windows logon prompt appears, and then stop and restart your computer.

  b. If your computer has multiple operating systems, use the arrow keys to select the operating system you want to start in safe mode, and then press F8.

  When you are in safe mode, follow the steps mentioned above to complete the restore of the system.

  Hope the helps of information.
