MacBook pro, blank white screen. Help!

My MacBook pro all of a sudden takes a long time to boot up. When I turn it on It gets passed the apple logo and then the screen goes blank white where all I can do is move the mouse around. After a couple of minutes of hangin on this white screen, the coloured wheel spins for a while and eventually brings me to the login screen. I have gone through nearly the whole list of the step by step fix your Mac document such as resetting smc, pram etc. I even reinstalled the OS and the problem remains. The only thing I haven't done is to completely wipe the HDD, reinstall the OS as a new machine again. But this seems like a very extreme process to go through to fix this problem. Once I am logged in however, the machine works like normal everything loads fine and it's fast, it's just turning on the machine takes so long to get to the login screen. Any ideas of what I could try before erasing everything of my HDD?

I'm thinking hardware issue. Run the Apple Hardware Test:

i called the repair services and they say its hard disk problem
so i would like to ask everyone here if the problem would be solved if i just changed the original hard disk to a ssd myself or do i realy need to let them repair for me.
ps : i dont have warranty

See A flashing question mark appears when you start your Mac. I would suggest you try reinstalling OS X.
If you are running Snow Leopard:
Reinstall OS X 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.
If you are running Lion or Mountain Lion:
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.

Krishnaraj7777,
you can try this: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Do you get past the white screen now?

Macbook pro reboot white screen

I had my computer plugged in and left it for 6 hours. My Macbook pro went to screen saver mode. I came back, hit the space bar and the circle spun and spun so I hit the power button. A minute later I reboot the computer. The screen came on and nothing else. I waited and waited. Nothing! When I barely touch the power button it turns off instantly. I hit the power button again to turn it on and same thing. Power light comes on very bright then dims and then blinks and goes out. When I hold the power button for a long time I here the power up sound and then nothing. What can I do?

MacBook pro crashes, white screen & lines on the screen

Hello, dear forum users, i need your help very much!
I am sorry for a long text, but i am trying to be detailed as much as possible.
I have bought MacBook pro 15' late 2011 model. I am very happy using it. Everything was working perfectly. A month ago i have updated my mac with SDD drive(Samsung ssd 256gb) & corsair 16GB rams. Up to now it was working perfectly, i haven't had any problems. But yesterday after i closed my mac(put it to the sleep mode) and after 10-15 minutes i opened it and there was just a black screen. No response to any of keys, mouse. After hard reset(holding power button. And turning it back on) i have received infinite white screen(i mean lightly gray). The one which follows after you turn on a mac. Waited a lot of time - nothing. Again hard reset.... again nothing. After some time i launched it successful. 5 minutes working - got completely blue screen. I thought it is because of software. When i restart mac, every second time, it works (not getting into infinite light gray screen). I made a backup on external hdd. When I am successfully logged it, it works like perfect. But then(sometimes immediately after logging in, sometimes after 15-20 minutes of work, sometimes after 2 minutes.... randomly) screen just freezes - no response to any key or mouse. And after 5-10 sec mac automatically restarts.
When i run mac in restore mode(cmd+r) it works good... I formatted sdd and installed completely fresh maverics software. Didn't helped. After 30minutes work screen again freezed and mac restarted after 5-10 sec. After restarting i have got "problem report for os x", and here is what it writes:
Your computer was restarted because of a problem.

There was also very weird behaviour of my mac, i have captures the video. I have uploaded it to the youtube, here is the link, please see it:
http://youtu.be/ossDHVRl7DE     -on the video you can see slitted screen and white lines all along the screen.
The thing is that i am now studying abroad, in Denmark, and any computer repair there is extremely expensive. And I dont have warranty anymore. Could you please help me and say how serious it is and what it might be? :/

I thought these strips are caused by PCIe , second video card, but then I launched virtual machine (just to make computer switch to the second video adapter to see it something will change). Now virtual machine is working in the background, Mac is working on the second video adapter - nothing bad happens.(just as before)... But then suddenly, out of nowhere it ether gets freezed or strips appears on the screen(as on photo above)
Video how it freezes
http://youtu.be/uTrWuvphNQs
I was just continue "working" with that and then happen this:( please see video attached)
http://youtu.be/QM7oCRlzt9M it lasted for ~20 second and I was pressing some random keys on the keyboard... And then it got back to normal.. :///

When I turn on my macbook pro, the white screen displays a file with a question mark in the middle. What does this mean?

Suddenly, my macbook pro has experienced problems. When I turn on my computer, the white screen displays a flashing file folder icon with a quesrion mark in the middle. Has my hard drive burnt out? Thank you in advance for any helpful suggestions..

It means your computer is search for a start up volume. You need to reboot into recovery mode and attempt to repair your disk. To do this restart the computer and hold the keys:
<command> + r
Then open Disk utility.

Upgraded MacBook Pro to OS X Yosemite, now all I see is a blank white screen?

After more then five hours of installation, all I'm left with is a blank white screen, does anyone have any suggestions? This is supposed to be seemles, I trust apple upgrades, was I wrong to be so trusting?

Hi Daniel,
Welcome to Apple Support Communities.
It sounds like your MacBook Pro isn’t starting up normally since upgrading to OS X Yosemite. The article linked below provides a lot of information and troubleshooting suggestions that will resolve most issues like the one that you’ve described.

So does it include in the replacement program of the logic board with free of charge ?
Will apple help me do the replacement if I'm able to charge that fee even my warrany voided ?

It really doesn't make a bit of difference whether someone else had an experience similar to yours. It's still up to AppleCare to deal with it.
But you can certainly waste your time here for whatever you think you'll find. Good luck.

Macbook does not shut down or restart. It stops at an blank white screen with the cursor moving around it. Updated to the latest software

I have a Macbook Air 13.3" 2012 model. For a couple of days my Macbook does not shuts down. It just stops at a blank white screen with the cursor still hovering around it. I have to shut it down forcefully every time using the power button.

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter "BOOT_TIME" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Note the timestamps of the BOOT_TIME log messages, which refer to the times when the system was started. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Select the messages logged before the boot, during the time something abnormal was happening. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
For example, if the system was unresponsive or was failing to shut down for three minutes before you forced a restart, post the messages timestamped within three minutes before the boot time, not after. Please include the BOOT_TIME message at the end of the log extract—not at the beginning.
If there are long runs of repeated messages, please post only one example of each. Don’t post many repetitions of the same message.
☞ When posting a log extract, be selective. A few dozen lines are almost always more than enough.
☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
Step 2
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A crash report has a name that begins with the name of the crashed process and ends in ".crash". A panic report has a name that begins with "Kernel" and ends in ".panic". A shutdown stall report has a name that ends in ".shutdownstall". Select the most recent of each, if any. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot. It's possible that none of these reports exists.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
☞ If you don't see any reports listed, but you know there was a crash or panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
☞ Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.
