White Screen and rebooting

can be using my phone and when i recieve a call or text it will freeze the screen will go completly white the red light on the front of the device will show then it will reboot it self this also happens when trying to open messages and emails and even when scrolling up and down the apps.
i have wiped my device with the blackberry software and reloaded it several times with different software bundles and each time the problem reacures even if i dont restore my personal settings and i have also removed the memory card.
can anyone help me in fixing this issue?

Hi juniorehi
Welcome to BlackBerry Support Community Forums
You can try Jl Cmder to wipe your device , to get error 507 means no OS then try any other OS pack from your carrier MTN .:
How do I wipe the BlackBerry using Jl Cmder?
After loading the new OS don't restore anything from the backup as you did earlier, Restore only your contacts. Then run for it for a few hours to see if problem appears ,If problem persist then On your homescreen go to manage connection > Turn off your Mobile Network . Locate a wi- fi and Connect your device and see if your device freezes or reboots while on wi - fi , If it does not then you the problem is within your device it may be any hardware compnent or SIM card slot and can be fixed by Mobile repair Shop or any BlackBerry Service center.
So Please try it and Good Luck ..

This is my first mac, it is a macbook pro. i restarted it but when it started back up i saw a white screen and then it prompted me to insert the reboot disk. anyone else have this problem?

I recently bought a Macbook Pro, this is my first Mac. I restarted it, but when it started back there was a plain white screen and then it prompted me to insert the reboot disk. Has anyone else had this problem and is there a way to do this manually like with PC's?

The new Mac's came with OS X Lion 10.7 and there are no boot disks.
Since it's so new, take it back to the Apple Store and let them deal with it.
If not you can hold Command and r (as in rotten) keys down and boot the computer.
You'll be presented with a several options, including one to reinstall OS X Lion provided you have a Apple ID, which means you have to use Safari in there to set one up. To do that you need to set up a email account with Google or Yahoo. Once you get the ID, then you can download Lion and reinstall it.
It's so stupid not having a copy of the OS on hand to perform your own repairs.
Of course Apple will be happy to sell you a $69 Lion USB stick.
Like I said, take it back to the store, and try to get your money back, that will force them to think about just giving you a replacement machine that works.
Lion doesn't work really but it can be acceptable until the patches get released.

Not used my G5 Powermac (late 2004) for ages. Only boots in with Installation disk, but colour dots on white screen and message comes up to reboot machine. Nothing happens.

Not used my G5 Powermac (late 2004) for about 2 years. Was going to set it up for the lads to do school work.
However it only boots in with Installation disk, but colour dots on white screen and message comes up to reboot machine. However nothing happens apart from me keep trying. Also the numerous fans get louder and louder and louder.....
Any ideas folks

Can you please provide details on the exact model?
For a start, the PRAM battery is likely dead. PRAM tells the computer which drive to start with, other basic information. Still, you can usually get the computer to start, though bad PRAM is unpredictable and could be stopping that.
Some computer models use software to control cooling fans. If there's no software commands they automatically go into high speed to prevent overheating. Your software obviously isn't loading, so runaway fans.

My iMac started and locked onto a white screen. Rebooted and all was well. How do you do a safe start i.e. what key do you press?

It should according to http://support.apple.com/kb/ht1455. Review that and try again.

Just let the battery drain until the screen shuts off. When you charge it back up it should boot up normally.

Hi Shahenaz,
It's a little difficult to understand exactly what's going on with your mac based on the description you gave. Is there anything else you could add? Is it stuck in a reboot loop? Or is it just showing a white screen forever?
I had pretty much the same problem a few days ago, and was worried my mac was screwed permanently, but I got it fixed up no problem!
Follow these steps to try and troubleshoot/fix the problem.
1. Boot into OSX Recovery Mode
First, turn off your Mac. If it isn't responding, or is stuck in a reboot loop, just hold down the power button until it turns off, and you hear the fans stop. Then boot it while holding the Command and R keys. If it successfully boots into OSX Recovery Mode, continue with this step. If not, skip to step two. (My Mac couldn't successfully boot into the recovery mode, so I had to go to step 2)
Select "Disk Utility" from the list of options, and find your built in hard drive from the list on the left. Usually there are two listings/names for your drive. The first should be something like "500GB longchainoflettersnumbers Media". Then the one below will be a little easier on the eyes, named Macintosh HD, if you haven't changed its name. That's the one you want, click it.
Now go to the "First Aid" tab. Click on the "Verify Disk" button in the bottom right corner, and let it do its thing. Once that's done, hit repair disk, also in the bottom right corner. If your disk is corrupted, you may need to run the repair process several times, before it comes up completely clean.
Once this is done, select Shut Down from the Apple menu and, once your Mac is completely off, turn it back on like normal. If it works, great. If not, proceed to step two.
2. SafeBoot
Sometimes, when a mac is acting up and doesn't want to start, all it takes is a safe boot, followed by a regular restart. Or maybe you recently installed a program that either has malicious or errored coding that's causing your troubles. This is where Safe Boot comes in.
Turn off your mac, and reboot it while holding Shift. (If you want to see the process that's going on in the background, boot while holding Shift, Command, and V. This will enter something called Verbose Mode).
If it boots successfully into Safe Mode, great. If you believe that there's a particular program that you recently downloaded that might be causing your trouble, now's the time to delete it. If not, just reboot normally and see if it works! If it doesn't, or if your Mac didn't even Safe Boot like mine, proceed to step 3.
3. Fsck!
For this step, you're going to be booting your mac into Single User Mode. I'm not going to go into details as to what this step does, but it works for some people. Here are the steps.
Turn off your mac, and reboot it while holding Command and S. The screen should go black, and you'll see some white text run across the screen, wait a few seconds, until you see the command prompt. Now type
fsck -fy
and hit the Enter key. This will run a series of system checks, which could take a few minutes. Be patient on this part. Once it's done, it will show one of two messages:
1. "The volume (your Mac) appears to be OK
or
2. "File System Was Modified"
If you got message 1, type reboot and press Return. Hopefully your computer works after this - if not, proceed to step 4.
If you got message 2, run the same command again until you get message 1. If it doesn't seem to be working, turn off your system and proceed to step 4.
If you couldn't even boot into Single User Mode in the first place (like me), go to step 4 anyways.
Step 4: Reset the NVRAM
The NVRAM is another kind of RAM that stores data like the computer volume you had set before you turned it off, or the screen brightness, resolution etc. This memory is saved, unlike with regular RAM. Resetting it isn't harmful to your system, it will just put your screen brightness, volume, etc. to defaults.
Turn off your Mac, and reboot while holding Command, Option, P, and R, and continue holding them down until you hear the computer restart again.
I can't really explain why to do this step, I just know it works for some people, and seems to be what unbricked my MacBook Pro. If none of these steps, fixed your Mac, well the situation is looking pretty grim. Try setting up a meeting with a Mac Genius at your local Apple store. However, I know that many other people with these symptoms ended up having a logic board failure. Apple can swap out your logic board for a new one, but the price is pretty hefty, somewhere around $300 I believe.
Well I wish you luck, I hope this helped you!

HT1338 i cant get in to os system. the screen just stuck in white screen and apple logo

i can not get in to my os system. the screen just stuck in white screen and apple logo

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
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 3
Boot in safe mode. Note: If FileVault is enabled, 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 damaged and the drive is probably malfunctioning. In that case, go to step 5.
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 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
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 6
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 7
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 backup.
Step 8
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

My 13" macbook just stopped working. When you turn it on you get a white screen and hear a repetitive clicking sound on the left side. Is this the hard drive? Any suggestions on replacement drives?

Put your install DVD into the optical drive (CD/DVD drive) and reboot. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option Key until the Install Disk shows up) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is, then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions. After repairing use Startup Disk from the same menu to choose your hard drive for restarting from your hard drive.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

My mac book pro has a white screen and won't start up

My Mac book pro has been running slow, so I thought I would shut down and reboot. It wouldn't reboot past a white screen and an apple logo. I have rebooted several times and after an hour or so it still won't go any further. Any suggestions?

Howdy Lowana42,
Welcome to Apple Support Communities.
It sounds like your MacBook Pro has a startup issue that is causing it to only display an Apple logo. Try the suggestions in the article below, they will resolve most issues like this one.

Was just opening page on Chrome when computer went to white screen and became unresponsive. Did this several weeks ago too. Disk tools find no issues.

While trying to open a link on FB, my computer went to a white screen and become unresponsive. I had to do a hard close. It did reboot and the Disk Aid finds no problems when I ran Verify Disc. This happened 2 weeks ago as well and I had to do a Safe mode reboot. Things seem a little slow when I use internet-Google Chrome (updated). I have a MacBook Pro with OS X 10.9.4 I'm not sure what else needs to be done? I'm not supertech savvy.

Hello! Since you don't have the startup disk your best shot is using fsck. Tom
when you re-start, hold down the apple key AND the "S" key You'll start up into a command line interface.. it'll look strange but just hang in there. When it's done booting up, you should see something that looks like this: localhost:/ root# at this point, type in 'fsck -f" please note the space before the dash, and of course, ignore the quote marks, then hit return You computer will no go thru some low level checks on your HD. Most likely you'll get a list of a few files that have problems and this procedure will fix them. This should take about 2 or 3 mins, so don't be in a rush. When the line says "VOLUME WAS MODIFIED", this means that changes were made. At this point you should be back at the same localhost:/ root# prompt. run fsck -f again. Wait for it to finish. if you continue to get the "Volume was modified" message, continue to run fsck -f until you'll get a prompt that says The Volume(your HD) appears to be ok, again with the localhost:/ root# prompt. AT this point, type reboot, hit enter and your computer will start up normally. This is not difficult, but you may want to give it a shot when your feel you have a few moments where you can attempt something new and not stress too much.

20" Imac has white screen and freezes at start-up

my 20" imac will not start....help...All I get is a white screen and tone at start-up then it stays white. I tried hooking up a bootable firewire drive and pressing the alt/option key at start up nothing. I also tried the command/option/p/r at start up, it will reboot to the same screen. I also tried running the hardware diagnostics at start-up...no response. Computer was purchased on Nov .4 2007, warrenty just expired.
Help......Please....

I had the exact same problem today. My iMac 20" (iMac 8,1) would't boot any more, staying stuck on a white screen immediately after the normal start-up chime. Nothing worked (no safe mode, no DVD boot, no disk selection icon when starting with alt pressed, no Apple hardware test, no parameter RAM reset, power management chip reset had no effect, no verbose mode, not even open firmware).
I browsed the forums, but what I found didn't help, so I was about to stop trying and have it fixed by Apple. But my son told me he had noticed that after "a long time" (he's 4...), a folder with a flashing ? would appear. I figured that wouldn't happen in case of a severe hardware failure, so I tried one last thing: I hooked up an old PowerBook in target disk mode via Firewire and restarted the iMac. I tried several times (with and without alt pressed), but nothing happened (when pressing alt, a functional mouse pointer would appear, though).
Then I restarted a last time and left the iMac sit there on its white screen for about 20 minutes... and that's when the miracle happened: it finally booted off the target-disk mode PowerBook's system!
I ran Disk Utility, which saw the iMac internal HD as disk2s0 (or something like that), and launched the disk repair process. After about three error-ridden verify-repair cycles, the green ok message finally appeared and the volume mounted as if nothing had happened. I rebooted off the internal disk without a glitch, and I still have to find damaged or lost files.
I guess I was lucky that my HD problem was benign enough to be cured by Disk Utility. But even if that had not been the case, at least I'd have known that the HD failed, and maybe I could have saved some files using recovery software. Whatever the case, if you've got an external bootable drive, it's definitely worth trying before handing your iMac over for (usually horribly expensive) repairs.
Good luck!

My ipod 4g has a frozen white screen and will not turn off, any advice?

My daughter's ipod 4th gen (only 4 months old, bought direct from Apple) suddenly has a frozen white screen and will not turn off. We cannot reboot it by pushing and holding the two buttons, even when held up to one full minute. When we plug it into the computer, the computer does not recognise it nor does iTunes, so we can't even do a full system restore. Help! Any suggestions of how we can reset to factory settings without using iTunes please?

- Let the battery fully drain. After charging for at least an hour try :
iOS: Not responding or does not turn on
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Iphone 4s will not turn on, you can not restore with itunes. What to do? Phone lit white screen and nothing can be done

iphone 4s will not turn on, you can not restore with itunes. What to do? Phone lit white screen and nothing can be done?

Reboot computer. Open iTunes on computer. Connect iPhone to computer with USB cable. Hold both home and power buttons until iTunes recognizes iPhone in Recovery Mode. This usually takes about 20 seconds of holding both buttons. Click the Restore button of iTunes. If still problem, all iPhone 4S have full Warranty. Make Genius reservation and take to Apple for resolution.

Each time i press the power button i just have a blank white screen, and intermittent sounds/tone. No apple logo, or spinning circle.

I used to install the rEFIt to boot with win7. When I deleted win7, I didn't uninstall rEFIt. Nothing wrong with it. One day after I watched movie in full screen,I pressed esc to quit. Then I found the touchpad didn't work. I can't turn off air. I just pressed power button for a little while. It rebooted, then my nightmare just began...
I have tried everything, PRAM, command+R, literally everything. No change.
But when I plug a CD-ROM with USB, I can only here one BONG, just once, then white screen, Like waiting for something...
I took it to a service center in China, they told me the CPU had broken. SInce it's one month out of warranty, they wanted to charge me for like $250....
I really don't think that's CPU's problem. I checked the history, it seems like somebody else also had the problem before.
Can anyone give me some hints??? Thanks!!!!!! Or I have to take it back to America to check....

Impossible, there are zero, as in none, zip, nadda viruses for OS X. If you have viruses on it they are for MS Windows and will not affect OS X. I suspect the hard disk has crashed, if you have backup then it's not a big deal to have it changed, just take it into your local Apple Store or AASP for service. If you have not been backing it up you may be in for a painful lesson on why backup is critical.
