White screen when I turn on the computer

My Macbook Pro would not let me click on anything so I restarted my computer by holding down the power button, but then it stayed at a white screen for awhile, then turned to a blue screen before my login screen poped up. It let me log in but then would not let me click on anything after that. When I moved the mouse cursor where my dock would be it does not appear. Then after a half hr of it still not allowing me to do anything I restarted it again and now it is stuck at a white screen. I am not sure what is going on because my computer was working completly fine yesterday. Im not completly positive on my operating system, but I know its a 10.5 something.

That happens. One day it works fine the next not at all.
Do you have the original system discs that came with the system? Id you do get the OS reinstall disc and insert it into the DVD drive and reboot (hold down power button until the system shuts down then pres the power button again to start it back up). When it is starting hold down the Option key and if a screen comes up, other then the white screen, select the DVD disc to boot from. If that starts up then open Disk Utility and check the SMART status of the drive and Repair Disk and Repair Permissions.
But I suspect the drive has failed and will need to be replaced.

Gut white screen with flashing apple and circle/warning sign on white screen when i turn on the computer

When i turn on my computer, i get only a white screen with a gray apples in the middle, flashing, alternating with a ghostbuster-type warning. Never get to the galaxy screen. Just happened today.

Did you setup a lock code? I have done this operation via iCloud just few minutes ago and it's booted with 4 numbers lock code just fine. When you lock your Mac, it's restarts automaticly and then loads with lock screen and you are only able to enter password of 4 numbers to unlock it.

Nothing on the screen when I turn on the computer?

Hi, my laptop( hp g62) is turning on but nothing is appearing on the screen?

Hi ChevChelios, welcome to the HP Forums. I will use a random model number of a G62 as reference (G62-140US). I have included the start up troubleshooting document. Find the symptom that most closely matches, and follow those steps. Perhaps "Symptom: LEDs glow, fan noise is heard, but display is black or blank" matches based on what you described.
Computer Does not Start (Windows 7, Vista, XP). I hope this works for you.
If you require further assistance, please provide the model number, and the installed version of Windows, as well as the results of the previous troubleshooting done.
How Do I Find My Notebook Model Number?
Which Windows operating system am I running?
I look forward to your response.

White screen when I turn the Satellite M50 on

I intermittently just get a white screen when I turn the computer on. Usually the problem is solved by switching the computer off and trying again - but sometimes I get a white screen again.
It seems to be connected to use of external devices - can anyone give me clear instructions about what should/should not be connected when I start and shut down the computer? Or any other suggested solutions?
Thanks

Thanks for your reply/advice - and the tip about Antivir. I used to use AVG and then Norton came as a package with this laptop....will have a re-think when my subscription need renewing.
I have updated the display/graphics driver but am still having the same problem of a white screen at boot-up. On reflection I think it is possibly a loose connection as I have just been a long trip with the laptop - including a fairly bumpy 4 hour bus ride - and I recall having the same problem several months ago which self-corrected after a similar trip (taking it down to a Toshiba ASP who never saw it as they were closed for the week-end and I had to get back to work!). This may sound strange but I took the laptop for a walk yesterday to see if any loose connection would shift and it then booted up on the second attempt rather than the 8th!
I guess I'll have to take it to the ASP - unfortunately it's no longer under warranty.
EDIT:
Problem solved. High temperature caused this issue

Why does my Mac stay on the white screen when I turn it on?

Why does my Mac stay on white screen when I turn it on?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 3
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 4
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 5
Boot in safe mode. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 6.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 6
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 7
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 8
Repeat Step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 9
This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 10
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

The initial white screen doesn`t appear, but the computer starts normally.

Hi, I'm worried about something. I have a MacBookPro 15 ", and since yesterday when I turn it on, the initial white screen, with the loading bar, doesn`t appear. At first everything is black and then the computer turns on normally.` That is not normal, can anyone help me?

Yes, I normally get this white screen when I turn the machine on. Whithout seen nothing behind it. But now is not appearing anymore. I turn it on > everything goes black (should be white with the apple and the loading bar) > then the screen of the user and password to access the computer appears normally.
What can this be? I searched in the internet, and found nothing. I`m hoping to find the solution here.

Please a simple problem but I don't know how to solve it. After installing 16 gb of ram all is good but when I turn on the computer it is a window signaling that all is correct. How is possible to delete once and for all that window? Thank you

Well then maybe you could take a screenshot because the appearance of such a window is news to me.
Also post your OS X version and what model Mac you have. The more detail, the better. Thanks.
To take a screenshot hold ⌘ Shift 4 to create a selection crosshair. Click and hold while you drag the crosshair over the area you wish to capture and then release the mouse or trackpad. You will hear a "camera shutter" sound. This will deposit a screenshot on your Desktop.
If you can't find it on your Desktop look in your Documents or Downloads folder.
When you post your response, click the "camera" icon above the text field:
This will display a dialog box which enables you to choose the screenshot file (remember it's on your Desktop) and click the Insert Image button.
⌘ Shift 4 and then pressing the space bar captures the frontmost window.
⌘ Shift 3 captures the entire screen.
Drag the screenshot to the Trash after you post your reply.

my ipod touch in white screen when i connect to the itunes can'tbe detected

If not sucessful try:
Try:
- iOS: Not responding or does not turn on
- If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

How do i stop my programs from automatically popping up when i turn on the computer?

how do i stop my programs from automatically popping up when i turn on the computer?

When you log out or shut down, there will be a checkbox that asks you if you want to reopen windows when you log in. Just uncheck this box. If that isn't it, you may have login items turned on. Go to System Preferences>Users and Groups and then under your name click the Login Itens tab. Make sure nothing is there.
If you want to stop windows from restoring when you open applications (so for example when you open Safari it doesn't open the 50 tab page you just had open when you quit) go to SystemPreferences>General and then hit the checkbox that says Close windows when quitting an application.

In windows 7, how to make firefox start automatically when I turn on the computer

In Windows 7, how to make Firefox start automatically when I turn on the computer. Note, I am asking how to do this with Windows 7, not xp, not vista.

You need to place a shortcut to open Firefox in the Start > Programs > Startup folder.<br />
That is basically the same in all Windows versions.

My new ipod nano does not work when you turn off the computer

I bought a new iPod but I have a problem when you turn off the computer does not work. Shows that the battery is full and it was lightning. Ipod only works while connected to your computer. What should I do

Hello pepi95,
And welcome to Apple Discussions!
If you just bought the nano, why not bring it back for a replacement or your money back? It's definitely a defective iPod. Not much else for options here. Sorry.
