Any known reason why bootcamp would start with black screen ?

I just got bootcamp installed on a brand new mac pro with two Apple displays.
I was able to start up my machine successfully with bootcamp (windows XP) and with mac OS.
I am able to run the bootcamp partition from VMware. However, recently, I have not beel able to boot into windows.
All I get is a black screen once the windows logo disappears.
Any idea why bootcamp suddenly refuses to boot with windows but has no problem doing so with CMware Fusion ?

You probably want to look through VMware Fusion about what is happening.
http://communities.vmware.com/community/vmtn/desktop/fusion
BootCamp is just a way to help format drive partitions. Beyond that, it adds HAL and Apple Services.
With Mac Pro, the ideal is to use Disk Utility and 2nd drive, partitioned as Master Boot Record.
Fusion and a BootCamp partition do make it more complicated. Fusion over writes graphic drivers - or did.
Windows Recovery Environment and Safe Mode would be first step.

IOS app starts with black screen when compiled via ADT (Flex 4.6, AIR3.7)

I was using Flex 4.6 with AIR 3.1 in Flash Builder 4.6 on Windows 7. I used two build methods: 1) "Export Release Build" in Flash Builder during development and 2) the ADT toolchain on my build server.
For the ADT method I would create AIR intermediate files using:
"C:\Program Files (x86)\Adobe\Adobe Flash Builder 4.6\FlashBuilderC.exe" --launcher.suppressErrors -noSplash -application org.eclipse.ant.core.antRunner -data [PATH_TO_SOURCE] -file [PATH_TO_BUILD_XML] [PROJECT_NAME]
Where my build.xml looks like:
<?xml version="1.0"?>
<project default="main">
    <target name="main">
        <fb.exportReleaseBuild project="[PROJECT_NAME]" basefilename="[BASE_FILE_NAME]" verbose="true" destdir="bin-release" />
    </target>
</project>
From these intermediate AIR files I would create my APK and IPA files using ADT like so (shown for iOS):
echo [CERTIFICATE_PASSWORD]|"C:\Program Files (x86)\Adobe\Adobe Flash Builder 4.6\sdks\4.6.0\bin\adt" -package -target ipa-test -provisioning-profile [PATH_TO_MOBILE_PROVISIONING_FILE] -storetype PKCS12 -keystore [PATH_TO_DEV_CERTIFICATE] [OUTPUT_PATH] [PATH_TO_IOS_AIRI]
This procedure produced working iOS and Android apps as well.
I decided to upgrade AIR to version 3.7. I used the overlay proceedure described here (http://helpx.adobe.com/x-productkb/multi/how-overlay-air-sdk-flex-sdk.html). I also updated the namespace in my project to reflect the new AIR version. Using "Export Release Build" in Flash Builder produces working copies of both the iOS and Android apps. Furthermore, the secondary method (used on my build server), produces both APK and IPA files without error. The APK works just fine but the IPA does not. When running the app on an Apple device, it starts up with a black screen and stays this way.
To summarize:
Flex 4.6, AIR 3.1: "Export Release Build" and ADT tool chain produce working APK and IPA files.
Flex 4.6, AIR 3.7 using overlay procedure: "Export Release Build" produces working APK and IPA files, ADT tool chain produces working APK file but IPA file loads black screen on Apple devices.
More notes:
I had made a back up of the "4.6.0" directory that holds the Flex and AIR SDK files. If I replace the overlayed Flex 4.6.0 SDK directory with the original (which contains AIR 3.1) and revert the namespace back to 3.1 in my project, everything goes back to normal and I get working apps via both methods described above.
Edit: I also should note that I've tried many other combinations of Flex and AIR (Flex 4.9.1 from Apache and AIR 3.5/3.6), which all produce the same issue. It seems that the overlay procedure breaks something for ADT with iOS specifically...
Edit 2: I also noticed that the IPA files output by methods 1 and 2 are slightly different. Opening these with 7-Zip I see that most of the files are the same, but some differ slightly in size (this was due to 'ipa-test' vs 'ipa-ad-hoc'). The odd thing is that in the IPA file that does not work (produced via the ADT method), the SWF file is named "swf3465180827438224920.tmp" while the SWF in the IPA that was created using "Export Release Build is named "[PROJECT_NAME].swf". It almost appears as though ADT fails to rename the temporary SWF file. I also realized that the "Export Release Build" method likely used '-target ipa-ad-hoc', so I tried this in the ADT method with the same result.
Any thoughts?

Hello Nimit,
Thank you for your response. I have tried AIR 3.8 Beta and this did not correct the problem. I downloaded the AIR 3.7 SDK from http://airdownload.adobe.com/air/win/download/latest/AdobeAIRSDK.zip . I have also tried with the new compiler as well, with the same result.
To keep things simple, I've created a very lightweight example with which I see the issue. I've also been able to remove the Flash Builder step and reproduce the problem with mxmlc and adt only. Since the files are simple, I will just post them here.

Create the above files in a single directory. Run the following to get a working IPA (method 1):
> mxmlc +configname=airmobile TestApp.mxml
> adt -package -target ipa-test -provisioning-profile [PROVISIONING_FILE] -storetype pkcs12 -keystore [CERTIFICATE] TestApp.ipa TestApp-app.xml TestApp.swf
To reproduce the problem, run the following (method 2):
> mxmlc +configname=airmobile TestApp.mxml
> adt -prepare TestApp.airi TestApp-app.xml TestApp.swf
> adt -package -target ipa-test -provisioning-profile [PROVISIONING_FILE] -storetype pkcs12 -keystore [CERTIFICATE] TestApp.ipa TestApp.airi
If you unpack the working IPA (from method 1) you will see the file "TestApp.ipa\Payload\TestApp.app\TestApp.swf". However, if you likewise inspect the IPA created via the AIR intermediate method (method 2), you will see the file "TestApp.ipa\Payload\TestApp.app\swf1970057761096800694.tmp" and there will be no "TestApp.swf". In both IPA files, if we inspect "TestApp.ipa\Payload\TestApp.app\Info.plist", we see the snippet:
        <key>CTInitialWindowTitle</key>
        <string>TestApp</string>
        <key>CTInitialWindowContent</key>
        <string>TestApp.swf</string>
        <key>CTMaxSWFMajorVersion</key>
        <string>20</string>
        <key>CFBundleSupportedPlatforms</key>
So I suspect "TestApp.ipa\Payload\TestApp.app\swf1970057761096800694.tmp" is incorrectly named, cannot be found at runtime and thus displays a black screen.
This problem is observed when using AIR 3.7. It is not observed when using AIR 3.1.

Qosmio F50-125 starts with black screen after an BIOS update

Hi
after instalation if new bios (v 2.0), computer sometimes starts with the black screen .
Even the first page that show press f2 to enter the bios is not shown.
Do you have somebody old version of the bios?
So I could try if it is the fault of it.

Hi
I think the old BIOS will not help you because the notebook would known that you are trying to update the BIOS to the older version and it would break up the procedure.
Furthermore the older BIOS is no available on the Toshiba European driver page.
I think just only a Toshiba ASP has got an older BIOS version.
Anyway, you said this happens sometimes.
This would mean that this issue doesnt persist always
Hmm. in such case I recommend settings the BIOS to the default settings and to update the display driver.
Check it out!

Adobe AIR apps start with black screen on iOS 8

AIR apps that worked fine on iOS 7 now just show a black screen and are unresponsive after updating to iOS 8.
Is this a known issue? Has anyone found a solution yet?

Found a resolution- the apps were published with the AIR 3.4 SDK. Republished with the newest AIR 15 SDK and they work properly in iOS 8.

What link, website? Firefox should not do that. Did you get FF from '''Mozilla.org?'''
It could be the work of one of your add-ons, or even add / mal-ware.
Look thru your add-ons list and make sure you know what each one is
there for. Also, check the programs that are on your computer
'''Windows > Start > Control Panel > Uninstall Programs.'''
'''(Mac: Open the "Applications" folder)'''
Go thru the list and use a web search to check any that you don't
know what they are.

Any Reason Why Should I go with MSI Twin Frozr II 6870?

Do you guys have any reasons why should I go with MSI Twin Frozr II 6870 than other reference card??

MSi is only one of two mfg w/utils to control voltage on their 6870's the other is ASUS. Price is a tad higher than some but the cooler is reference so its not like its a twin cooler or something like the 5xxx series or the 6850's custom design (not a twin cooler however). If you dont plan on OC and tweaking voltage its probably not an issue then foor spec the 6870. Id check out all, best price and warranty, some offer 3 yrs or lifetime. When a custom cooler becomes avail on 6870's (only 6850's have them now last i checked), then id have more to comment on and suggest.

Is there any particular reason why Firefox is running crappy this weekend?? I also have Google Chrome and that is running great.

Sorry, no further idea what can cause this.
Is the shortcuts file truely saved to disk? You can find in the user path, where the preferences and presets are stored for PS. Or if you go to the dialog again where you change shortcuts, is it reverted there too?

Macbook pro-Freezes with black screen at start up.

Macbook pro-Freezes with black screen at start up. I've tried inserting the Mac OS X install disc to run the hardware test(Restart and hold down D), But it still does nothing. Just the black screen. Now I can't get the disc out. I've tried holding down the track pad key upon start up but that doesn't work neither.
What do I do??? Please help.

Remove the battery to find your serial number in the battery bay. Then you can look your MBP up on EveryMac.com:
http://www.everymac.com/ultimate-mac-lookup/
That will give you all the information on your Mac.
This is assuming that you have the MBP with the removable battery and not the unibody. The unibody has different graphic chips.
Good luck!

Why do I have a black screen with the icon spinning round and won't open?

why do I have a black screen with the icon spinning round and won't open my photos?

Because there is a problem. Want to try fix it?
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

HP Pavilion DV7-1428ca _ CAPS + NUM LOCK Continually Blinks + Will not Start up Black Screen

Would appreciate any suggestions on the issue I am encountering.
I have an HP Pavilion DV7-1428ca that was left powered on, so it went into Safe mode (screen goes blank). Once I came back to my Laptop hitting any key would take out of of the Safe mode however this time it did not. It remained with black screen irregardless of buttons pressed.
Had booted and can hear the fan and hdd go for the 2secs then it stops to a Black Screen with the "CAPS + NUM LOCK" Continually Blinking. Tried to Hard Boot several times but the same thing re-occurs.
It does not seem to be blinking in a series a code, just a steady blink (every sec) for both the CAPS + NUM Lock for as long as I leave it on. HP Site provides a chart from 1-6 series of blink codes which does not seem to apply to me.
Being out of Warranty I am hesitant in bringing it to a local repair shop without trying any alternate trouble shooting first.
Thanks

Hi,
First of all, shutdown the notebook, unplug the AC Adapter unplugged, remove the battery, and then hold down the Power button for a full minute. Plug in the AC Adapter ( leave the battery out ) and see if the notebook will start.
