Take your Mac to someone who knows how to help you. If you STILL get to the recovery partition (the list of various choices, including reinstalling OS X), then something else is wrong, and you need to force it OFF again. Press and hold the power button to force your Mac power off. If any text comes up on the screen while you are holding the keys - you are not doing this correctly. If you don't hear anything, just keep holding the keys for about 2 minutes, just to allow your Mac time to respond - then release those 4 keys to allow your Mac to boot normally. Those keys, all of them, no others, Restart, then hold those 4 keys until you hear the second chime. Just as a reminder: Command + Option + p + r If you see any text, then you continue to use the wrong keys. Other than some screen flashing, which may or may not be visible - no menus, and no other text will appear. It only resets your Mac, and will continue to do that while you continue to hold all 4 keys. The PRAM reset does NOT start the reinstall, nor would it force you to reinstall if you don't want to do that. Any questions, post a comment.Why would you _choose_ to reinstall OS X? You can do this by going to the computer manufacturers web site and downloading it from there, i.e.
If the sound icon keeps disappearing over and over again, you need to update the driver for your sound card. That’s it! Sometimes this happens a lot, especially after you restart your computer or log off. Then, towards the bottom of the screen, go ahead and click on Turn system icons on or off.
First, make sure the volume icon behavior is set to Show icon and notifications. In the Notification Area Icons dialog box, there are two things you have to check. Now, you need to click on the Customize button under Notification area. To do that, you simply right-click anywhere on the taskbar and choose Properties. In Windows 7/8, to hide or view the volume icon, you need to customize the taskbar. This actually makes sense because the taskbar icon should be controlled by the taskbar settings. If you go to the Control Panel and click on Sounds in Windows 7/8, you won’t see any checkbox for adding the icon to the taskbar, but instead all the audio inputs and outputs on your system. You can always drag the icon out back onto the main section of the taskbar. It’s nice, but your volume icon may actually just be in the grouped icons rather than it’s own icon on the taskbar, so make sure to check that first. This is to basically save space and make your taskbar look less cluttered.
Also, in Windows 7/8, taskbar icons can now be combined.
In Windows 7 and Windows 8, the taskbar got a huge revamp and so the process is completely different. Now your icon should appear in the taskbar. Re-check the box and then click Apply again. If it’s already checked and the icon is not showing up, you need to uncheck the box, and then click Apply. You’ll notice the “ Place volume icon in the taskbar” option is either checked or unchecked. Once you open the dialog, you should already be on the Volume tab. Personally, I like Classic View better since it’s easier to get to what you want quickly.
