A system disc can be used for these repair options also, in your case if the DVD drive is not working you can use an external dvd drive if you have one.

Starup problem with black screen
Dear All,
for last few weeks my 4 year old macbook 10 showing black screen at start up while I can hear fan sound and sleep light on. It would only boot after some 20 minutes after several attempts. I have done smc, pram, restarted with safe boot but no help. also hard ware test showing no problem with hardware. I have also done repair disk. after start up system behaves normally but when I shut down and again press power button to start the same problem as mentioned above - black screen, fan sound, light on but no boot sound.
is this software problem? will taking backup and reinstalling software help?? Please help.
Thanks & Regards,light on but no boot sound.
No "chord" on startup means the Mac didn't pass it's startup diagnostics tests.
Try here > Resolve startup issues and perform disk maintenance with Disk Utility and fsck
It would only boot after some 20 minutes after several attempts.
If you can get it to boot to the desktop, check to see how much free space there is on the startup disk.
Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure there's a minimum of 15% free disk space. -
Videos on my device play back audio only, black screen
Videos I have taken on my device play audio but with a black screen since the 10.3.1 update. Bell, Z30, up to date.
Solved!
Go to Solution.Hi and Welcome to the Community!
A quick review of this site will reveal thousands with similar situations as yours. But, you only cited 3 of the 4 required octets of any OS level, so it's rather impossible to know anything for sure based on your information. BB has released at least 3 more updates in the last few weeks, but the carriers remain in control of release to their customers, and some are slower than others to do so (but BB cannot control them). Further, there have been many reports of issues with the "official" methods of installing these updates.
If you wish to jump ahead, you can use an AutoLoader to cleanly reload your current OS, load the even more current version, or fall back to whatever version you desire. The choice is yours.
Good luck and let us know!

Major Problem With Black Screens, Restarts, and Artifacts.
1. HP m7790y
2. Vista 32-bit
3. No error messages or BSOD.
4. No changes were recently made.
For about a month now, sometimes my computer will display a bunch of artifacts on the screen and the visuals won't change, but I think my mouse and keyboard still work. I can do CTRL + ALT + DELETE and that screen pops up with no artifacts, but as soon as I get out of it, the artifacts come back and the escape sequence doesn't work again. If I have a video going or music, I can still hear it for a bit, but then it gets screwed up. Then my computer does something that is like shutting off, but it isn't. The GPU's fan stops going, the screen goes black, and only the power light on my pc is on. Most of the time I have to push in the power button, and then turn it back on again. Sometimes it restarts on its own, and displays a screen asking me how I want to start up.
I've used the HP Hardware Diagnostic Tools and tested everything, but there were no errors for anything. I can even play video games for long periods of time just fine (Rome: Total War, The Walking Dead, Mass Effect 3, Company of Heroes). If the problem is going to happen, it happens within the first 5-10 minutes of me having the computer on. I've even used Furmark with stress tests and there are no problems.
This question was solved.
View Solution.Hello mpthemaster,
The issue you are experiencing is related to the video card, but we need to figure out if the problem lies within the hardware or the software.
Software is the easiest to rule out so let's start there. Your video card has drivers installed on the computer we need to uninstall the drivers that are there and reinstall new drivers to see if the issue goes away.
1. Navigate to the link below and download the drivers for your video card do not install just yet
http://goo.gl/dBmyj
2. Click on start and then type "Device Manager" in the start search box (without the quotes)
3. Open Device Manager and expand the display adapters section
4. Right click on your video card driver and say uninstall
5. Press the win key the right arrow twice and the letter R and your computer should reboot
6. After it reboots Windows will load a generic driver for the video card
This may or may not work. If everything on the computer looks fine (things are not blown up out of proportion and you are able to adjust settings) see if the issue comes back.
If the issue comes back or the generic drivers didn't allow you to use the monitor properly then install the link you downloaded earlier and again test to see if the artifacts come back.
The computer you have comes with a choice in video cards. Which video card do you have installed? Does it sound loud?
While you are at you might as well clean out your computer and make sure it's not dirty or dusty. Check all your fans and ensure each are in working condition and there is adequate air flow for the machine. Especially check the fan on the GPU and make sure it's not dirty or getting clogged.

Problem with Black Screen on T420s
Here is what I know:
The screen was black this morning when I turned it on. I can see the cursor but I nothing else shows up.
I tried to rollback to an earlier date but the only thing I had available was this morning so that was useless.
I tried the other Thinkvantage "repair" options and they didn;t do anything for me.
I can boot into safe mode but I'm not sure what to do once I get there. Is this a video card/driver problem?
The only thing I did yesterday was replace itunes11 with an earlier version of the software. Could that have done it? If so, how do I uninstall it at this point to see if that would work?
PS. Machines is 6 months out of warranty coverage.
Any help would be appreciated. Thanks in advance.Before I do that, just want to let you know that the screen in not completely blank the entire time, i.e. I get the Windows dance when I start the computer and the sign on screen to request my password comes up normally with the icon, the dialog box to enter my password,etc. It is only after I enter my password that the screen goes black.
The same thing during safe mode, I see white print on black along the border telling me that I am in safe mode but there is nothing in the middle of the screen. And I get a command line which I can use.
By process of elimination, does this mean there is something wrong with a graphics chip or driver or ?? Is there a way to test for that in safe mode using a command prompt?
Thanks, as always -
Problem with black screen and crashes after installing windows 7 and bootcamp
K, so I partitioned my internal HD using Bootcamp, installed a new copy of Windows 7 Home, put in my Mac OSX disk and installed the additional stuff. I can successfully log in to Windows and open the browsers I have installed: Comodo dragon and Mozilla FF. McAfee auto installed with FF and I have Comodo Antivirus installed.
However, within minutes of use, my screen goes black, the computer does not shut down and reboot, I have to press the power button and wait a few secs for it to shut down then reboot. This has happened from both browsers while in Windows on Facebook in a game; while trying to save an attachment from an email via webmail and also while checking the inbuilt Windows settings for the display.
The latter produced the following report (below) on reboot and when I hit the "look for a solution" button, the actual window vanished after a few secs.
2 additional bits of info which may or may not be related:
a) running windows troubleshooter I discovered I have prob with:
driver for Inter (r) 5 series /3400 series chipset Family USB Universal Host Contoller - 3B3B
- I Googled this and it seems a common prob. Tried the reinstall, didn't work, so disabled it as suggested on some of the forum posts.
b) The OSX side of my computer seems to run fine most of the time, tho I have had the odd back screen, then wait, press reboot to power on and off in past as related in this post last month: https://discussions.apple.com/thread/4844797 (maybe a kernal panic..???)
Would anyone know what is causing these probs or what I can do about them? My computer is no longer under warranty and the couple of times I had probs while it was, I was told the probs were to do with the power supply and given a new one, I'm not sure if they looked at the logic board. The OSX side has also had an ongoing prob to do with sudden shrinkage of the image content, which I mentioned to the geniuses at the Apple store b4, but as it wasn't acting up there they couldn't do anything about it... ( looks as tho sm1 changed the screen resolution and whatever is in the browser window shrinks, tho desktop, is never effected - if that makes sense!.)
All in all tho, does make me wonder if the prob is based in the graphics switching..???

R400 Facing problem with Black screen no display
It all started when i using net half way my screen freeze with lots of altered colors.
I have tried to oning laptop series r400 and it loads till windows screen and then it goes blank screen after that.
I am certain that the latop is still running and everything is fine just that there is no display output.
I have tried to enter the bios setup and changed the output from discrete to integrated output and also disabling the auto selection for display output (third option) and i found that it works so i probably guess problem could be with discrete display output.
However, i am not 100% certain that it is the main problem for this blank screen. Is there anyway i can verify this problem or best find the solution to it. Reply me thank you

I have a 2007 Macbookpro and it started up with gray checkered boxes and across the screen I tried to re load OSX and it work 1 day and started again is this a hard drive problem or Video? Now as it starts to load a screen comes up saying to restart over and over again
I'd suspect this known issue:
http://support.apple.com/kb/TS2377
if you have a late 2007 MBP.
The only testing you can do at home is to attach an external monitor and see if the defects repeat on the external. If so, get to an Apple store. If the computer's video chipset fails a test the Apple Store will perform, you get a free logic board replacement. Turnaround is usually one day to one week--not bad at all.
If the defects do NOT repeat on an external monitor, then the problem is not covered by the above Repair Extension Program
The issue is heat-triggered. Be certain that you control heat once you get it fixed. Don't use the computer in your lap without a lapboard; don't block the vents under the display hinge; don't us in clamshell mode, etc. -
I had a problem with imac screen going black. apple store diagnosed prob with video card which they replaced. Brought it home, turned it on (have done this 4 times) it starts up, wheel turns, there is a long bar at bottom which fills up, then it turns off
Apple guarantees their work, take it back.

I have a problem with black squares,rectangles, etc, in the contact list on facebook, but it is only in Firefox, I no longer know what to do? I'm using Windows 8.
'''Try the Firefox Safe Mode''' to see how it works there. The Safe Mode is a troubleshooting mode, which disables most add-ons.''
''(If you're not using it, switch to the Default theme.)''
* You can open the Firefox 4.0+ Safe Mode by holding the '''Shift''' key when you use the Firefox desktop or Start menu shortcut.
* Or use the Help menu item and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Don't select anything right now, just use "'Start in Safe Mode"''
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shift key) to open it again.''
'''''If it is good in the Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one.
Please follow the [[Troubleshooting extensions and themes]] article for that.

I am looking for anyone in the west Tennessee area using Wild Blue along with Apple IMac who is having a problem with their screen going complelely white every so often. Have had the maching into the Apple store in Memphis. They could not get it to fail. Help
TutorDaddy, if this Mac is still covered by the initial warranty or under AppleCare, take it in and have it looked at. As the old label used to say, there truly are "no user serviceable parts inside." Kernel panics very usually indicate failing hardware.
I have an older iBook G4 that started developing kernel panics and like you, despite reinstalling the OS from a freshly formatted volume, they kept continuing. I looked at the crash log and saw that in each instance of panic, the last bit of code to be accessed had something to do with AirPort. Knowing that the AirPort software was at then current levels, I surmised the problem to be a bad AirPort networking card which, on that particular model of the iBook, was a very small module attached directly to the logic board. Since the computer was out of AppleCare, I broke the machine down myself (I didn't realize that there could be so many barely visible screws in one machine) and removed the offending piece of hardware. My iBook lives but without WiFi, it now sits as a more or less desktop machine needing an ethernet connection to stay connected to a network.
I do not suggest you break into your iMac. First of all, I'm guessing one would need to be able to pull off the glass and have the necessary glue to reattach it, which is not really available to us consumers. If you're feeling adventurous enough to read the crash logs from each panic, you might be able to surmise the hardware component (or badly written application or library; it can happen) that's causing the panic. If it's a software issue, remove the offending software app and see if the panics return. If it's a hardware issue, it's best to let a competent service tech qualified on Apple hardware to handle it.
[edited to add:]
After browsing through related problems in the discussions, I saw this link to a third-party web site being handed out. Perhaps you'll find it useful: http://www.thexlab.com/faqs/kernelpanics.html
