i used the command F to go into Disk Utility. I clicked on my Hargrove and clicked erase. Then I restarted my comouter and it won't load up. I've tried so many things but nothing is workig? What do I do?

It won't "load up" because you erased the drive, including the operating system. There is nothing there to load...
Try following the instructions here: OS X: About OS X Recovery - Apple Support
You need to re-install OS X. You don't have a bootable drive right now.

Assuming Allan's advice is not correct, and you do run the installer, I think I've heard of that problem and it involves removing the old Flash plug-ins, then install the new version. I don't use it so I don't know what they are called, but will be the /Library/Internet Plug-ins folder.
You can go here and enable HTML5 in YouTube so you don't have to use Flash: http://www.youtube.com/html5
Most(?) of the content is HTML5, but you may run into videos where you still need Flash.

my Macbook Pro (OSX 10.6.7 2.26 GHz Intel Core 2 Duo) has started misbehaving on me. When I'm working, the cursor will start spontaneously moving to the in a straight line, and randomly right clicking on things.
If I close the computer and open it back up, it sometimes stops for a little while, then will spontaneously start again. Any help would be truly appreciated. Thanks!

See this knowledge base article. Also, you might want to update to 10.6.8 (don't know that that will fix your problem, but it's the latest version of Snow Leopard).

Last week, I had no problems streaming my MacBook Pro to my sony Bravia with a logix hdmi cable. I came back from holidays and now it doesn't work anymore. What settings should my computer be on and what settings should my tv be on?

Did you try booting off your Install disk holding the c key down. From here you can get to the drop down menu just a few clicks in (you are not going to install) and run the Disk Utility>Repair Disk. See if it will let you do this.

Kernel panics are usually hardware.
Hold down 'd' key and it should boot into Apple Hardware Test, or insert your OEM install DVD to do so.
No, we are mere users and mortals and usually you need to do some troubleshooting by trial and error and testing. Schedule an appointment.

I used to be able to access Appleworks. Now every time I hit the ICON, it just keeps stating I need to either relaunch, ignore or report. I recently changed my internet service to wireless from dial-up, would this cause appleworks not to open?

I used to be able to access Appleworks. Now, every time I hit the icon, it tried to open but doesn't. I recently upgraded to wireless internet from dial-up. Would this be the problem?

There is more than just the plist to delete for AppleWorks. They must all be deleted at the same time to be effective. To delete AppleWorks’ preference files, go to HD > Users > Library > Preferences. Find and delete the file com.apple.appleworks.plist. Find and open the folder AppleWorks in this Preferences folder, then delete all of the enclosed files (with the exception of the Button Bar Preferences if you have customized the Button Bars). AppleWorks will recreate the preference files as it needs them.

Hi
This sounds like a job for Disk Utility ... but that's located in the Utilities folder ....
Fortunately, there's a spare copy of Disk Utility on the setup disks you should have received with your computer. You need to boot the computer from the setup disk, then find Disk Utility. Inside Disk Utility, "mount" your hard drive and run Repair Disk, then Repair Permissions.
Good luck

Macbook Pro died and now won't connect to the internet

I just got home from college and my Macbook Pro died while I was using it because I couldn't find the charger in time to plug it in (stupid mistake that I never ever let happen usually). After I found it, plugged it in, and started it up again, the date and time were messed up on the computer. I reset them to normal and tried to connect to the internet using my old settings, but it hasn't connected.
I've tried a lot to try and fix it so far and it still won't connect. Other computers and devices (HP and Dell laptops, iPod touches, PS3) that my family have and use all work and connect to the internet fine.
I've tried to run the Network Diagnostics and after plugging in all of my settings and information, it says that it can't fix it. Next to it on the left, the Airport, Airport Settings, and ISP are all green...but the Network Settings is yellow and the Internet and Server are red.
I've deleted my internet settings and tried recreating them and that hasn't worked either. I have also tried the Assist Me portion to make a new connection - no luck there.
I've also tried resetting the Macbook Pro and the router (an Actiontec router for Verizon FIOS) multiple times and that hasn't worked either.
I unfortunately can't use Time Machine either because I don't have an external hard-drive and haven't set it up.
I just don't really know what to do at this point. Hopefully someone can help me out!

Same problem--hoping to get Apple's attention by throwing my hat in the ring with everybody else.
Things tried (now approaching 2 weeks of failure):
Deleting "Airport" Connection, Adding/Restarting/Re-adding/etc.
Archive Install
Erase & Install (full reinstall done by Genius)
Card Replacement
Bluetooth Replacement
Zapping the PRAM
Trying different connections/routers/locations/connection types/etc.
Visited Genius bar 4 times now.
Have been without the computer longer than I've been with it.
Trying to change over from a horrifically bad Dell to a refurb Mac worked once before...though I've come to believe: It's not the refurb, it's not the hardware, it's not the settings, it's not the router, it's not the install, it's not the associated software, it's not the connection, it's not the Super Moon that comes up tomorrow...It's a hardware issue as this has been happening since I opened the computer out of the box, and we have an identical computer running identical programs on an identical network with the identical updates and NO problems whatsoever--I'm assuming the innards may have been cheap'ed out somewhere to save a buck or a connector is faulty after a particular build date?
Full symptom list (in no particular order):
Connection Timeout
Connection Drop
Not recognizing Airport
Card Recognition but endless connection time
IP non-recognition
Random re-connect
Indication of connection without transmitting/receiving data

I have a 4g touch. I updated ibook in itunes and now, every time I sync, I get the message that the app won't run in os6. Is there any way I can revert the app in itunes so I have the latest version that will work with OS6?

I recently updated ibook in my Itunes. Now, every time I sync, I get the message that it won't update the ipod as ibook won't run in OS6. Is there any way I can revert the ibook app in itunes so it quits trying to install the current ibook app. I am trying to stop getting the warning message. I am also concerned if I ever have to reinstall the app.

Delete the app from the iTunes library on your computer and then transfer the version from iPod to computer by:
