Hi! My macbook before it bacame a blue screen, shows that the start up disk is almost full but i ignored it...and then suddenly it doesn't start up anymore and shows only blue screen with arrow...pls help! I don't know much about computers! :(

Boot up in Safe Mode.
Startup your Mac in Safe Mode
A Safe Mode boot takes much longer than a normal boot so be patient.
Once you are in Safe Mode, you need to delete data in order to free up disk space, ie., photos, video, etc.
When you are in Safe Mode, control click the MacintoshHD icon on the desktop then click Get Info. You'll see Capacity & Available. You need at least 15% available disk space.
Then click Restart from the Apple () menu.

Blue screen appears during start up and freezes

During start up the apple logo appears and locks up. Re booting results in blue screen. After re booting 3 or 4 times finally boots fine.

If you are still not working properly you might want to try the recovery mode http://support.apple.com/kb/HT1808
It is a useful link to keep in mind.

Satellite P100-347: Blue screen appears on start up - unable to boot volume

Recently I left my 2 younger brothers playing NFS Carbon on my satellite P100-347, preinstalled with media centre 2005 edition, and now it fails to startup.
During the startup process eventually a blue screen is displayed for about a second and then it shutsdown (I manged to make out the words "unable to boot volume" from the blue screen).
I tried booting with an XP media centre DVD but it only gives me an option of reinstalling the OS with a price of losing all my very important data. Normally I would have recovered the system but I don't want to lose my data.
Is there anything i can do other than taking it to a technician?

Hi
Well, mostly the BSOD appears due to a hardware problem or serious software issue.
In your case the software problem is possible
Unfortunately, I think the new OS installation is the best way to get the notebook running correctly.
Now you want to know how to save the data and files well, I think you should remove the HDD from notebook and should try to connect the 2.5 HDD via external USB controller to another computer. Then you could save the files on the other HDD
I think, now you know that the regular backups are important and necessary!!!!

Blue Screen Error during starting Windows Server 2008 R2 (VM on Hyper-v WinSvr2012) Using a Physical to Virtual (P2V) VHDX.

Hi There,
I'm trying to migrate one of my physical Windows Server 2008 R2 to Virtual Environment (Hyper-V on WinSvr2012).
(The original physical machine had multiple partitions on the windows HDD and 2 other boot able OSs where installed on 2 of those partitions ...) So anyhow, After heaps of trouble shooting and fixing the boot records, it finally started booting the
Windows but when it got to loading C:\windows\System32\Drivers\Classpnp.sys
and it crashed, a blue screen poped up saying "A Problem has been detected and windows has shut down to prevent damage to your computer ... ) and then system got rebooted automatically.
I have tried chkdsk, also tried copying a new classpnp.sys to replace the old one but no hope. I don't think is not a damage file issue. Not sure, but it is probably related to changing the HDD devices or SCSI/IDE controllers?
Any idea?

1. You have placed your problem in wrong forum. Address your problem to Server forum instead.
2. I do not think it is liable configuration. I have not heard about migration of multiboot HDD. Try to split it. Pay attention to better preparation. I would expect separate target VM.

After upgrading to Lion blue screen appears at start up have to reboot to log in

I have been having issues when I first downloaded and installed Lion it installed then when it rebooted a blue screen would appear and nothing would happen. I rebooted the system and it came up. Now I installed the latest software update and the same thing happend did the same steps. Yesterday I had to boot my computer up twice for it to get to the lion login screen. I have called apple and their resolution is to wipe out and restore from time machine. Has anyone else seen this issue?

Sounds like directory damage of some sort. A few options.
1) Buy Diskwarrior. Probably the premier tool for directory repair. There's a download version but it needs to be run from a booted drive which it seems you don't have. You can wait for delivery of the disc which will allow you to boot from the disc and run the application.
2) Buy an external firewire hard drive. Get one big enough for future backup use. Meanwhile, install a new version of the operating system on that drive, boot from the drive and see if you can even see the files on the main rive. If directory damage isn't too bad you may be able to copy critical ones, though the problem with directory damage is you don't know if you're copying a damaged file. That's when just getting Diskwarrior first may just make more sense.
OSX doesn't let you make a bootable disc just by copying files onto a CD the way OS9 used to. There's a utility called CloneX that does this, but I haven't tried it. Usually what you can do is clone hte internal drive to an external drive as part of backup. The cloning places a bootable copy of the OS onto the external. Simply dragging OS files across no longer works.
By the way, the external drive has to be Firewire in order for it to be boootable. USB is okay for backup but you can't use it to boot an older computer in an emergency (new Macs are okay).

There is always a blue screen appears after the Apple logo during the booting process. And then everything is back to normal. What is this thing? Is there something wrong with my screen or something?

HT3910 a blue screen appears at the start up

When I start my macbookpro a blue screen appears and stays. Nothing further happens ; can anyone help please?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
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. Ask for further instructions.
Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually login 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.
Test while in safe mode. Same problem?
After testing, reboot as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Blue screen appears on startup and at shutdown

A few months ago, I bought a macbook pro and it was doing fine. But recently, every time it starts, a blue screen appears for a split second then it goes to log- in. Then, every time I shutdown, it will also show up for a split second then shutdown. It doesn't affect the computer but I'm just wondering how to stop it.

I couldn't rember what time it started so, I shut down my computer and the blue screen appereed at 8:39:28. But went I turned it on, the blue screen did not show. So, I turnned it of and on again and no blue screen. I did it several times and now the blue screen isn't showing. But I will post the test that showed in the concel during 8:39, when it powered of blue, to the time I powed it on, when the blue screen did not show. If you need more, I will try to give it to you. I'll post again if it shows up again. Also I should edit out ethernet address too right?
Here's what its says:

Left speaker no sound, no wi-fi, hang up after first or second booting then blue screen appears

hi there! my laptop always hangs up everytime I open it. Sometimes it open up after minutes of waiting then gradually hangs up before blue screen appears. I had to long press the start button again and again before I could use it.
By the way, there are times I had to switch into safe mode and found out that the audio is not working anymore. During normal mode, only the left speaker is operational. Lastly, wi-fi signal will constantly disappear after rebooting.
please help

Hi,
Have not seen any reports of negative experiences (unlike recent Microsoft updates) from the last batch of Windows Updates.
I would guess you have a coincidental hardware problem.
A failed HDD would yield an error at boot. You would still be able to boot to the BIOS if you desired.
Normally failed devices (memory, GPU, CPU) will give audible and visual error codes. Exceptions will always happen.
Could be the battery, power supply, or maybe the motherboard has bit the dust. You will probably receive no visual or audible error messages when the motherboard fails.
Try booting with one monitor.

Sometimes Blue screen appears on Satellite M70

Hi there
I must express my overwhelming frustration with my satellite M70 laptop as I have it for more than a year now(warranty expired) and almost from the get go it had a problem in wich a blue screen appeared and the pc reboots...from the error report it is a problem with the graphics card and/or display driver.
I did take it to my local retailer for repair but the problem still remains(gone there 3 TIMES! each time waiting for more than a month for repair!and they did send it to toshiba service...)... as the problem doesnt happen *all the time* it seems they just didnt notice or something :(.
I did update all the drivers but it had no effect on the problem...
So now what?? Do I send it to repair and they finally replace the graphics card...but I pay??!!
This is all very upsetting for me as you might imagine...
And know its worse...it seems to be happening more and more...and many times the computer wont reboot after the bluescreen...it just stays black.
Now almost every time i turn it on it wont boot...the fan will just work for a few seconds and thats it.
Im almost certain the graphics card is defective...can I replace it at home? Argh this just feels wrong, the computer had this problem almost from the start and I sent it for repair...they just did not fix it...I shouldnt have to pay to fix it as I sent it for repair 3 times while it still had the warranty...
Please reply I'm desesperate and have no idea what to do

Hi Andrej and thanks for the reply
But the thing is I have already done that countless times...and the problem is still there...same old same old :(
I have tried seemingly everything...thats why I say its gotta be hardware :S
Having this in mind Id like to know if there is anything I can do(concerning hardware) without resorting to Toshiba service
Keep in mind that Im pretty sure it is the graphics card that is faulty(I dont know if its onboard or not)
Also sometimes when I turn it on the graphics on my pc go weird like an abstract painting or something lol...thats another reason to think its the graphics card.
So anyone can help me?
Thanks in advance for your replies :D

If nothing else works, you might try this one. It has worked for many others ...
Use iTunes to do a reset to factory default condition. Always be sure to do your backups before fiddling with your iPad. You might do both the iCloud and the iTunes backup, just to be sure!

keithfrommariettaOct 12, 2014 3:25 PM Re: IPAD2 very slow after IOS 8 upgrade
Re: IPAD2 very slow after IOS 8 upgradein response to pacoKAS
SOLVED: IOS 8 Issues on iPad 2:
I just returned home from a visit to the Genius Bar. Like you and many others, when I upgraded my iPad 2 to IOS 8, it became practically unusable. It was VERY slow, lagged whenever trying to to do anything. Lots of screen freezes and apps spontaneously crashing. I was convinced that the processor on the iPad 2 just couldn't handle the new IOS and I went in to see about restoring to IOS 7.
Thankfully, I was hooked up with a very sharp guy at the bar. The problem is not with the OS, it is with it being an *upgraded* OS. He used the analogy of when you had an older Windows computer and how over time (and over upgrades), they just tended to get slower and slower because of all of the garbage that was carried forward in the upgrades. At those times (and if you've ever had a Windows computer, you get this), the only thing that would speed it up would be to wipe the machine and do a fresh install of the current OS and then reload your apps, and the viola, everything would be fast again. Well, it turns out that IOS can suffer the same problems.
THE FIX: FIRST, be sure you have a current iCloud backup of your device. Connect your iPad to a computer that has a clean fresh copy of IOS 8 on iTunes (this is best done with a computer other than the one that you sync your device to because you DO NOT want to restore it from a back up just yet). Ideally, if you do this at an Apple store you'll be assured of the right version there and someone to answer any questions you might have along the way. You then hold the power and home button down to hard-reset the device and continue to hold them down until it reboots into recovery mode. You then follow the instructions on the computer to reinstall the OS on the device (which wipes everything from it and then reinstalls a clean copy of it). Once this is done (which only takes about 15 minutes), your device will reboot and ask you to set it up. Answer the questions about language, location, etc. and continue until it asks you to log into your iTunes account. Once you do that, it will ask if you want to either 1) Set it up as a new device, 2) Restore from iCloud, or 3) Restore from iTunes. Choose (2), restore from iCloud. This will ensure that it brings down "clean" copies of all of your apps and preferences rather than the potentially corrupted ones that might reside in your iTunes backup. That's it! It will take a few hours depending on how much data and apps you have, but I am happy to report that my iPad 2 is now running IOS 8 and it's running as fast as it ever did when it was brand new!
To sum it up, this process 1) Wipes your device and the garbage causing your problems, 2) Loads a clean and bug-free version of IOS 8 to your device, and 3) restores your apps and data so that it looks just like it did before the wipe, with the exception that it works now! :-)
Note also that by following this process you don't have to go through the painful and laborious process of reloading all of your apps, data and/or settings. iCloud takes care of all of that for you.

When I quit Firefox 7 a blue screen appears

When I quit Firefox 7 a blue screen appears. I go to quit Firefox 7 and then the screen turns blue and I have to press the power button to reset my computer. I'm running OS X 10.6 with the most recent updates. This seem to have started to happen when I updated to Firefox 7. I'm still checking to see if it happens on other applications.

I've got the same problem on my 2011 MacBook Pro (2.3ghz Core i7, 4gb Stock Ram, Intel 320 SSD 120gb).
I noticed it was happening a lot on a previous installation of OS X 10.6.8 using the combo update. I kept getting blue screens pretty much on command when quitting firefox, though I first noticed it happen trying to install Microsoft Office 2011.
I reinstalled OS X 10.6.6, updated to 10.6.8 using 'Software Update' via internet and the last couple months have been fine.
TODAY, however, quitting Firefox after closing down a bunch of tabs caused the system to freeze up and give me a blue screen. I remember I was able to replicate this problem by quitting firefox after closing 5+ tabs. Can't seem to do it on command now, but I'm hoping this problem doesnt reoccur anymore.
I bought an apple product based on its claims for being reliable. I need to get work done without headaches.

Re: Satellite A300-29n - blue screen appears on setup of XP?

Hello
I'm working on windows vista and facing no problems
when i wanted to set up XP on the machine ,after loading the files of the windows

every thing was going well
a blue screen appeared (a problem has been detected and windows has been shutdown to prevent damage to computer ...........................)

Maybe you should continue to use Vista and you will not have any problems. ;)
Which WXP do you use? Which SP?
Is HDD recognized properly? I mean can WXP installation be started or not?
The whole story is strange. I have A300 too and use WXP and Win7 as dual boot. No problems at all.

Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk. You could have some directory corruption. Let us know what errors Disk Repair reports and if DU was able to repair them. This could just be a start in repairs and you may need a better utility to finish the job.
Then Repair Permissions.
No need to report any Permissions errors........we all get them.
