Please help

If there is no loading bar, it's usually a problem with a third party kext file in OS X itself.
You can press the power button down to force a hardware shutdown, then reboot holding the shift key down on a wired or built in keyboard, this will disable them and you go around and update your third party software.
Gray, Blue or White screen at boot, w/spinner/progress bar
Also take this time to backup your users files off the machine if possible.

MacBook Pro suddenly will not boot up. Blank screen with message File is possibly corrupt. Header checksum does not match, etc
Hi s.cheslik,
It seems your MacBook Pro will not boot properly and it displaying an error message. Based on the information you have provided, it appears your MacBook Pro needs to be serviced. The following link should help you get started with the process and has links with additional information on topics such as warranty and service pricing, battery replacement, and express replacement service.

How can I fix this graphics problem on my Macbook Pro?
Whilst playing numerous games on my Macbook Pro, I have noticed the same problem. This causes the game to be almost unplayable and usually happens after playing the game for a while. I have had this happen on many games such as Portal 2, World of Warcraft, Team Fortress 2, Starcraft II and a few others.
I have had this problem ever since I first got my Macbook Pro, but the issue has changed slightly since. A software update a long time ago caused the problem from affecting the whole screen to just affecting the window the game was being played in.
I can sometimes fix the problem by opening the Display preferences in System Preferences and it automatically fixes itself - without me doing anything. There is another way I have found to temporarily fix the problem, however this has only worked on World of Warcraft. It involves changing the reselecting the display in the video settings and reapplying it - causes the game screen to go black for a few seconds and the issue is resolved.
The problem is that the graphics on the screen start to flicker and move about and certain sections are missed out. It's kind of like a fuzzy tear in the screen.
I have a attached an image of the worst case of this that I have had (I managed to screenshot it).
System Specs
Model Identifier: MacBookPro7,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.4 GHz
Memory: 4 GB
Chipset Model: NVIDIA GeForce 320MDoes it do the same thing if you boot from a different disk, like your old Mac OS X install disk? I see you're running Lion, so also try booting from the recovery partition by holding down command and r at startup.
If it can't boot from any system, it's a hardware issue. You'll need to contact Apple for service. If you can boot from the recovery partition, try repairing the hard drive with Disk Utility. You may also want to try running Apple Hardware Test. -

When I power up my Mac-Pro I only get a flashing file folder with a ? inside the folder. I suspect my hard drive is maxed to capacity can anyone help me as to what I should do?
Whatever the problem is you no longer have a bootable system. You need to try reinstalling OS X.
Reinstall Snow Leopard without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless. -

What's wrong with my macbook pro (15" early 2011) when i connect it with TV via hdmi
What's wrong with my macbook pro (15" early 2011) when i connect it with TV via hdmi
Hello Alex,
It sounds like you are getting excessive CPU usage when connecting an external display via HDMI to your computer. I would try the troubleshooting steps outlined in the article named:
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/ht1573
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the systemYou can reset the Mac's parameter RAM and SMC.Reset the resolutionStart by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.
Cheers,

On my new iPhone, at the Apps store, I tried to make a purchase, the popup screen shows my Apple ID and asks for my password, but no keyboard appears so that I can enter the password. How do I get the keyboard to appear??
On your iPad, delete the existing account then sign back in with the new ID and password.

I am having some trouble with my computer, what happened was: I was playing on a game, I played with a magnet, it started to go slower and slower, I pressed F9 then it went slower and then it went to a blank screen with a flashing document with a question mark on it. I tried the original OS X installation disk but when it came to choosing the area of which I save it, it showed no areas.
Startup your Mac while holding down the Option key. That should prompt the Startup Manager window where you can select the startup disk then click Restart.
If the startup disk is not available from that window, you may be able to repair the disk.
