If a Mac is shut down while the volume is set to zero, the standard Apple startup chime will not sound, so it is impossible to say whether or not this symptom indicates a problem.
For a startup issue such as this, I would recommend zapping the PRAM and resetting Open Firmware.
To zap the PRAM, start with a powered-down machine, press the power button, then immediately hold down the four keys: command, option, P, R. After ten seconds or so, you should hear the optical drive reset, and then the startup chime (because the volume is reset to full by this procedure). Ten more seconds, another reset, another chime. After the second time you hear the chime, release the keys.
Shut the machine down again (if it doesn't start up successfully, hold the power button until the power goes off). Press the power button, then immediately hold down the four keys command, option, O, F. You will see some tech-speak on the screen, then it will wait for input. Enter the following three lines, pressing the "return" key at the end of each:
reset-nvram set-defaults reset-all
After the last line, your Mac will reboot itself. It should now boot much more reliably. If it doesn't, chances increase that you have a hardware problem. You may want to run the Apple Hardware Test from the DVDs that came with the PowerBook to check your memory and logic board. Failing this, you are in for a trip to the shop.

    FixYa website reformatted those three lines into one. Let me try again, double spacing them:


    reset-nvram


    set-defaults


    reset-all

Tip

How To Upgrade Mac OS X Tiger 10.4.* to Snow Leopard 10.6.*


Apple recommends that if you wish to go from 10.4 to 10.6 then you should purchase the <a href="http://www.amazon.com/Apple-MC581Z-A-Mac-10-6-3/dp/B002I0JKE2">10.6 Box Set</a>.<br /> <br /> <span style="font-weight: bold;">System Requirements to run Snow Leopard:</span><br /> <ul> <li>Mac computer with an Intel processor</li> <li>1GB of memory</li> <li>5GB of available disk space</li> <li>DVD drive for installation</li></ul> <span style="font-weight: bold;">Snow Leopard Installation Instructions:</span><br /> <ol> <li>Just insert the DVD in the optical drive.</li> <li>Restart your Mac while holding down the C key.</li> <li>You will be guided through the installation procedure and be prompted at one point to choose which install option you want.</li> <li>Once the Snow Leopard install is completed the Mac will restart itself.</li> <li>You will probably be asked to register with Apple upon restart.</li> <li>Enjoy Snow Leopard on your Mac!</li></ol> <b>Q: Can I upgrade directly from Mac OS X 10.4 (Tiger)?</b><br /> <br /> <i>A: Yes. Apple recommends purchasing the Mac Boxed Set for this purpose, which will also update iLife (it is unknown at the time of this writing whether older versions of iLife work with Snow Leopard) and iWork. Also note that while it has been said that the $29 upgrade will work with 10.4, it is not officially supported and may be in violation of the licensing terms.</i><br /> <br /> <b>Q: What happened to the different install options? Can't I do an Archive & Install?</b><br /> <br /> <i>A: Apple has revamped the familiar installation options for Mac OS X. You now have two choices, either a straight upgrade or a clean install. Supposedly if you choose to do a straight upgrade, what actually goes on behind the scenes is what was traditionally known as an Archive & Install.</i><br /> <br /> <b>Q: Is there anything I can do to better prepare myself for the upgrade?</b><br /> <br /> <i>A: Yes. It is advisable to run a Verify/Repair Permissions and Verify/Repair Disk in Disk Utility. You may also want to run the maintenance tasks in <a href="http://www.apple.com/downloads/macosx/system_disk_utilities/onyx.html">Onyx</a>. And finally, it would be wise to get your applications up to date using a program like <a href="http://metaquark.de/appfresh/">AppFresh</a>.</i>

S3842 uk FREEZES ON BOOT every time have to switch off. on 3rd or 4th attempt works fine. any new software that requires reboot - it does this without a problem. started 2 months ago with original Vista...


Upgrades are usually troublesome as they leave bits of the old OS in odd places. It is best to do a clean install.
Choose your OS, either Vista or Win7. XP will not work!
Always download the latest drivers for the OS you are using from hp.com or it will keep hanging and be unreliable.
Hope this helps.

APPLE IMAC G4 - TRYING TO INSTALL OS WITHOUT DISK EJECT BUTTON


Reastart the iMac and at the same time hold down the mouse left click button. If that does not work.
  1. Restart the computer.
  2. Immediately after the startup sound, press and hold the key combination Command-Option-O-F.
    Note: The Command key has the Apple and (commandkeysymbol.gif) icons on it.
  3. Release the keys when you see a white screen that says "Welcome to Open Firmware."
  4. At the prompt, type: eject cd
  5. Press Return, then wait a few seconds. The disc drive should eject any disc that is present, and "ok" appears behind your command when the action is complete.
  6. Type: mac-boot
  7. Press Return.

Since Upgrading to tiger I have freezing,and startup problems,the display graphics aer wobbly with information missing


See if it will boot while holding down the shift key. This is a safe boot without any startup items and it automatically runs a disk repair.

Once booted open Disk Utility (found in application\utilities) and run Verify Disk to see if the repair was successful.
