Try booting from original DVD that came with your computer and running "Disk First Aid".

Apple MacBookPro 2010 is in a white screen


If the start up sound plays and the hard drive sounds normal try connecting the computer to an external monitor. If the external monitor shows the desktop just fine then the cable connecting the laptop to its screen is probably going bad.

If the computer will not boot at all try zapping the PRAM by
  1. Pressing the power button and then command-option-p-r before the gray screen comes up.
  2. Hold those keys down until you hear the startup chime.
  3. Let go of the keys and let the Mac reboot.
If that doesn't work try booting from an install disk and run a repair utility.

Macbook stuck on load up screen


When you say "load up screen", I assume you mean the Apple boot screen (it has the apple on a gray background).

You might try resetting the PRAM on the macbook.
You can do this by pressing and holding the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

So, turn the macbook completely off. Turn it on and immediately press and hold the Command-Option-P-R keys until the computer reboots and chimes. Once it chimes, release the keys. Your system should boot normally.

White screen of death on Macbook 13". when turning


You may need to reset the PRAM.
Start your computer and hold down the option, command (apple), P and R keys simultaneously until you hear the second chime. Then release.

This will reset the perimeter RAM (PRAM) and may allow your system to start, which it will do immediately if it capable.
If this is not the case and you have already tried removing the RAM and the HD, you may need to have the motherboard tested.

MacBook won't start up.


If you have your Mac OS X Install disc, insert it into the drive.
Restart the computer and hold down "C" while booting.
Choose your language.
Select "Disk Utility" from the "Utilities" in the menu bar.
Select your Macbook's hard drive in the left sidebar.
Click the "First Aid" tab thats along the top of the viewer window.
Click "Verify Disk" (not verify disk permissions)
If this shows errors click "Repair Disk"
Once completed close the Disk Utility window.
Restart the computer.
If this fails to fix it as well then your next option would most likely be recovering your files from the macbook either by booting into target disk mode (hold down T at startup) and transferring them via a firewire cable, or removing the hard drive and hooking it up to another Mac to get the files. Then do a clean install of Mac OS X using your installation discs.

Mac book chimes on start up but no screen comes on


Make sure the MagSafe adapter is securely attached to the Macbook and free of debris.

There are two procedures that are advised by Apple to assist in resolving issues where the Macbook chimes at start up, but displays no video.

Here is the first procedure:
Here are some steps you can try to resolve the issue:

• First, hold in your power button for approximately 10 seconds to do a hard shutdown, if you have not already turned your Mac off.

• Once your Mac is shutdown, you will need to perform what is called a PRAM reset (Parameter RAM)

• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously .

• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

• Now, hold the keys down until the computer restarts and you hear the startup sound for the third time.

• Release the keys and allow the Macbook to start up.

Observe to see if your Macbook will boot to the Desk top normally. If it does not, here is the second procedure:
-------------------------------------------------------------------
-SMC RESET-
The System Management Controller is an integrated circuit (computer chip) that is usually on the logic board of your Mac computer.

It is responsible for power management of the computer. It controls backlighting, hard disk spin down, sleep and wake, some charging aspects, trackpad control, and some input/output as it relates to the computer sleeping.

• If the computer is on, turn it off.
• Disconnect the AC adapter and remove the computer's battery.
• Press and hold the power button for 5 seconds
and then release the button.
• Reconnect the battery and AC Adapter.
• Press the power button to restart the computer

Update me if you require further assistance.
