Won't respond. Have a blue screen that keeps flickering.

My MacBook pro is not responding. It has a blue screen that keeps flickering. Power button does not even work.

Safe Boot by restarting your computer while holding down the "shift" key. Safe booting disables all nonessential processes, often times allowing you to start up when you would otherwise crash.
As of OS X 10.5.6 Safe Boot deletes the dynamic loader shared cache location in the /var/db/dyld directory. A corrupt cache here can cause the blue screen crash. Once you restart normally, the cache will be recreated. This should take care of the issue.

Computer won't get past the blue screen...

During class today I decide to install new updates to my computer, but class ended before everything had downloaded so I just closed the screen thinking nothing of it. Now my computer won't get past the blue screen and it just keeps reloading and reloading. Help?

You must have damaged your OS installation by putting the machine to sleep at the wrong moment. To fix that, you need to reinstall, but first you need to back up your data, if you haven't already done so. Have you?

IMac makes a loud beep on start up, won't load past the blue screen and the black ticking dial appears every few seconds in centre of screen.

Urgent help!
Out of the blue my mac lost the mouse cursor even though it had connection so I rebooted only for the mac to make a loud beep on start up then get stuck at the blue loading screen. It won't load past the blue screen. I've tried to reboot holding down the shift key but no change. I've also shut down, unplugged the main for 15 seconds, re plug and wait 5 seconds before starting up again but no change. Does anyone have any suggestions?
PS: I'm not too sure which systems I am running without being able to check in about this mac. I bought my imac in January or February 2011 if that helps.

The power on self-test resides in the ROM of the computer. This test runs whenever the computer is turned on after being fully shut down (the power-on self-test does not run if the computer is only restarted).
If a fault is detected during the test, you will not hear a normal startup chime. Instead, the system will beep as explained below. If you experience one of these beeps, you may call your Apple Authorized Service Provider for additional troubleshooting assistance.
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable

Reset PMU and Powerbook won't boot past the blue screen with "Mac OSX" box

Hi-
Problem: I tried to reset my PMU, and now when my computer restarts it won't go past the blue screen with the "Mac OSX" logo in the box (and progress bar, that never fills up). I then also tried to reset PRAM, but it still won't boot properly.
Backstory--
I've had my 12-inch Powerbook G4 for about 3.5 years already, so things are starting to get a bit out of whack. I replaced my battery about 3 months ago, which has been great, but recently my power-cord has been wonky (having to unplug it and replug it in to make sure it actually charges the computer, the light flickers on and off, etc). Today it actually started producing SPARKS at the place where the thin white wire meets the white plastic power brick, so I decided it was time to get a new one. Brought it home, plugged it in, and since it seemed like the battery indication icon on the menu bar was all out of sync with the powercord colored-light, I tried restarting it a few times, but still the same. Then, I decided to reset the PMU, which may have been a huge mistake. And now it won't boot past the blue screen... Any advice? I'm going to try restarting it in "safe" mode, but I'd be so grateful for any recommendations. Hope I haven't done something irreversibly stupid with the PMU reset.
Thanks,
Samantha

Hello all,
Thanks for all of your great suggestions and info-- here are a few responses.
1) The disk I just borrowed from my friend appears to be the full retail version-- it looks just like the links that Ali B sent, and is in a large box saying "Mac OSX Tiger, version 10.4"... will this be the proper disk to do an Erase and Install? The only other disks I have came with my Powerbook when it was originally purchased, when it came Panther (I think, 10.3?). Would I use both sets of these disks to do erase and install? Or only the Tiger OSX disks?
2) I get the sense that Disk Warrior or Tech Tool might be necessary, but does it make sense to TRY to do erase-install before buying them? Also, are there any downloadable (for pay) versions of this, or would I need to track down the actual physical disks in Hong Kong or wait for them to be shipped?
3) I haven't yet tried the S.M.A.R.T. test, should I do that first? What is the procedure? Are there any results or ways to know if the drive is too far gone (so that I might instead replace the internal hard-drive) instead of pay 100 USD first to do the disk repair?
4) Cornelius said: "An alternative would be to completely reformat and erase the entire HDD, then re-install and restore your data from backup. If your backup is in the form of a bootable clone of the entire HDD, you can just clone it back." I use Super-Duper to back-up and the most recent one copied the whole thing-- what would be the later procedure of "cloning it back"?
5) As I'm able to use my computer pretty normally right now, but does it still mean that it might crash/die at any moment? Is there any way to tell?
Thanks so much!

HP Pavilion Entertainment won't start just shows blue screen

HP Pavilion Entertainment won't start just shows blue screen. Sometimes says missing operating system after changing boot order. I have seen error message 303. This happened after I couldn't stop coolncheap popups so I saved everything to another computer and did a complete restore. When I was in the process of getting it back to working order I allowed updates recommended and optional and then everything started.

Also pressing F11 won't take me to recovery

My Macbook has a blue screen that wipes to gray with little squares??

When waking up my MacBook it'll have a totally blue screen that wipes to the gray log in screen with my curser. It wipes in little squares. Once I wipe clear enough to see my log in box and put in my password, it clears up and logs on.
What does this mean? Is my LCD going bad?

If it's gotten past the hardware tests (assuming you mean the ones on your Install disks) then assume for now that the problem lies in the OS rather than the hardware. That means, for one thing, that you're actually in the wrong forum and should be moving over to the Mac OS X v10.4 Tiger section, probably the Installation & Setup forum you'll find there.
On the way, take a look at the contents of the following KB article. It will get you started on the troubleshooting of this problem, and reporting what you've done from here (and what the results were) will speed the process in the other forum.

I have dead blue screen after downloading the ios 7.1.1

I have dead blue screen after downloading the ios 7.1.1.
What should I do to fix it?

Hello hagarar,
If your iPhone started displaying a blue screen after running a software update, I suggest the steps in the following article.
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIs and corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Thanks for reaching out,
-Joe

I have a blue screen on my ipod 4g and it will not do anything? What do i do?

I have a blue screen on my ipod 4g and it will not do anything? What do i do?

Try resetting:
Hold the home and power buttons at the same time until the Apple boot logo appears. No data will be lost.
If that doesn't work, just let the battery drain. Once you charge it back up it should work as normal.

I updated my first generation iPad to version 5.1.1 and won't go past the setup screen that asks if I want to use the iPad locator. I can go back but can't get any further.

I updated my first generation iPad to version 5.1.1 and won't go past the setup screen that asks if I want to use the iPad locator. I can go back but can't get any further

I just updated my original iPad 32 GB WiFi to iOS 5.1 about fifteen minutes ago. But I did it with the system restore feature in iTunes. So it wiped out everything on my iPad. But it did work. Then I restored an earlier backup and all went fine. Maybe you could try backing up your iPad and then using Restore to get it back to factory settings to see what happens.

I have a white screen that pops up every time my 3gs Sleeps, I have reset it, restored it, etc.. Any suggestions on how to fix this? when it isn't showing a white screen it seems to be fine, so frustrating

I have tried almost everything and I still have a white screen that pops up

Reset to factory settings if that doesn't work, take it in to the Apple store.

Have a Blue Screen issue, read this from Apple...

Just posting a link for people who may have the blue screen issue, I snagged this from another thread in hopes of bringing it out front more: http://docs.info.apple.com/article.html?artnum=306857

Hello rita240,
The steps below can help resolve issues with your iPhone's display.
This can include bright or dark pixels, lines in video, or sections of video missing.
Try turning iPhone off and then on again.
Verify the issue is not content related, by viewing different content.
If the image is too dark, adjust the brightness. In General Settings choose Brightness and Wallpaperand slide the slider.
My issue is still not resolved. What do I do next?

Hi, I have a specific website that keeps blocking me from going to website I want to view. It is called vnebo.pro or mobi. I also have a pc computer with Kaspersky and it blocks it. How do I remove it or block it from my computer.

Hi,
I have a specific website that keeps blocking me from going to website I want to view. It is called vnebo.pro or mobi. I also have a pc computer with Kaspersky and it blocks it. How do I remove it or block it from my computer? It only appears at my home, when I use my mac at other places I don't have a problem.
Thanks for any help!

Thank you for the reply. I wanted to wait awhile in order to ensure that this corrected the issue. For a brief while, it did! However, it did not take long before the screen began once again hijacking my home button presses. This occurs even with Firefox removed from default applications ( triple-checked ).
This never happened before version 35.

Won't respond. Have a blue screen that keeps flickering.
